Math Riddles for Kids

These math riddles with answers turn numbers into a game. The cards run from counting warm-ups to number hunts that punish a fast guess, and the sneakier ones come with hints so nobody gets stuck for long. Guess out loud first, then tap to check.

Kids math riddles turn on an everyday fact, a misread sentence or a number read as a word

Read the first clue and decide what it is made of. A clue can name a quantity you already carry around, such as the legs on a dog, the value of a nickel or the twelve inside a dozen. Say that value out loud before writing anything down, because the card turns into ordinary arithmetic the moment the word becomes a number.

The move that pays is deciding what a card is really asking before reaching for a number. A quantity can be handed over and then dropped: eight turns into the word ate, an eight cut across the middle falls into two rings, and forty is the number whose spelling climbs in alphabetical order. Elsewhere two conditions are stacked so that one number survives both, and the habit worth building is testing the tighter condition first.

Our math brain teasers page wants real working, with rates and averages and squares sorted into three grades. The arithmetic here is lighter, and the difficulty sits somewhere else: in how carefully you read the sentence, which is why seven crows on a fence and ten birds in a tree look like the same card and want opposite answers.

  1. Riddle 3: most people say One apple. One is what the bowl has left, and the bowl is not who the question asks about. The word you tells you whose hands to count, and the two you carried off are sitting in them.
  2. Riddle 47: most people say First place. The card names the runner in second, not the one in front. Overtake somebody and you inherit their position, so the leader keeps the top spot and never even learns you were there.
  3. Riddle 57: most people say Eight sheep. Seventeen take nine is the sum the wording seems to invite, but all but nine names the ones that stayed. The number given is the answer already, and no subtraction belongs anywhere in the card.
  4. Riddle 65: most people say Two and six. Two times six does make twelve, which is why that pair comes out first. Their total is one too many, and the only other way to reach twelve with single digits brings the sum down to the number asked for.

Decide whether a card wants a sum, a remembered fact or a second look at the spelling, and name that choice before you answer.

  1. 1. I'm a number that looks exactly the same when you turn me upside down. What am I? Easy

    Need a hint?

    Try writing some numbers and spinning the paper.

    Show answer

    8. Flip it over and it's still an 8. Zero works too!

    Turn the paper, not the value. This digit is drawn as two stacked loops, so its top and bottom swap places and the shape on the page reads the same either way.

  2. 2. There are two ducks in front of a duck, two ducks behind a duck, and one duck in the middle. What's the smallest number of ducks this could be? Medium

    Most people first say: Five ducks

    Need a hint?

    Line them up single file.

    Show answer

    Three ducks walking in a line. The first has two behind it, the last has two in front, and the middle one is in the middle.

    Nothing here promises five separate birds. The wording lets one bird hold two jobs at once, so a single file row of three fills every position the sentence names.

  3. 3. There are 3 apples in a bowl and you take away 2. How many apples do you have? Medium

    Most people first say: One apple

    Need a hint?

    The question asks what YOU have, not what's left in the bowl.

    Show answer

    2. You took them, so you have them!

    The last four words decide this card. They ask about your hands, and the pair you walked off with is already there while the bowl keeps a separate count.

  4. 4. I'm greater than 5 but less than 7. What number am I? Easy

    Most people first say: Seven itself

    Show answer

    6.

    Both limits squeeze in from either direction, and the reader supplies the unstated rule that the answer is a whole number. Less than means stopping short of the edge, never landing on it, which is what rules out the larger boundary.

  5. 5. How many sides does a circle have? Medium

    Most people first say: No sides at all

    Need a hint?

    It's a silly answer, not a geometry answer.

    Show answer

    Two: the inside and the outside.

    Side carries two senses, and the punchline picks the one that means a region of space. One curved boundary still splits the world into what lies within it and everything beyond.

  6. 6. I have 4 sides that are all exactly the same length. What shape am I? Easy

    Show answer

    A square.

    Equal edges fix distance only, never corners. A tilted rhombus with no right angle meets this clue as well, so the pivot is the right angle that nobody stated: readers supply it without noticing.

  7. 7. Add me to myself and you get 10. What number am I? Easy

    Most people first say: The number twenty

    Show answer

    5, because 5 + 5 = 10.

    Myself is the clue that ties the two parts together, so split ten into twin shares and each share is the hidden number.

  8. 8. Count the legs: two dogs and one bird go for a walk. How many legs in total? Easy

    Need a hint?

    Dogs have 4 legs, birds have 2.

    Show answer

    10 legs. Each dog has 4, so that's 8, plus 2 for the bird.

    Each animal has to become a number before any adding starts. Group the two equal counts first, four and four, then set the bird's two on top of that eight.

  9. 9. What did one math book say to the other math book? Medium

    Show answer

    I've got so many problems.

    Problems is the pivot word, and a textbook is packed with the exercise kind. Said aloud by a book, the same word borrows the meaning a worried friend would use.

  10. 10. Mary's dad has five daughters: Nana, Nene, Nini, and Nono. What's the fifth daughter's name? Medium

    Most people first say: The name Nunu

    Need a hint?

    Don't guess Nunu. Read the question again.

    Show answer

    Mary! The riddle told you her name in the very first word.

    The list of almost matching names sets up a pattern, and the pattern is bait. The girl this family belongs to was introduced in the opening word, and she counts among the five like her sisters.

  11. 11. How many fingers are there on ten hands? Easy

    Need a hint?

    Count one hand first, then multiply.

    Show answer

    50, because 10 hands times 5 fingers is 50.

    Hands are the unit being multiplied, and a hand carries five when the thumb counts too. Work out one palm, then stretch that figure across ten of them.

  12. 12. What number comes right after 9,999? Easy

    Show answer

    10,000.

    Adding one in the ones column finds nowhere to put it, since every column already sits at its ceiling of nine. Each nine rolls to zero and a fresh digit opens on the left.

  13. 13. Seven crows sit on a fence. A loud dog scares one away. How many crows are left on the fence? Medium

    Most people first say: Six crows

    Need a hint?

    Crows don't wait around to be counted.

    Show answer

    None. When one flew off, the noise scared all the others away too.

    Birds are not counters you can subtract from. A dog loud enough to scare one off scares the whole line beside it, so the fence empties instead of dropping by one.

  14. 14. I'm a shape with exactly 3 sides and 3 corners. What am I? Easy

    Show answer

    A triangle.

    Counting corners adds nothing here: once three straight edges close up, each pair of them meets at one corner, so the second clue repeats the first. Spotting a free clue saves you from hunting for a fourth property.

  15. 15. If two is company and three is a crowd, what are four and five? Easy

    Most people first say: A party

    Need a hint?

    Stop thinking about people and just add.

    Show answer

    Nine, because 4 + 5 = 9.

    The opening line is a familiar saying, and it tempts you to reply with another crowd word. Once the sentence reaches its last clause, nothing in it mentions people, and plain addition takes over.

  16. 16. What time is it when an elephant sits on your alarm clock? Medium

    Show answer

    Time to get a new clock.

    The question wants a clock reading and receives a set phrase instead. Time to get something new is what people say when a thing is broken, and it names no hour at all.

  17. 17. How many seconds are there in one year? Hard

    Most people first say: Way too many to count

    Need a hint?

    Think about dates, not clocks.

    Show answer

    Twelve! January 2nd, February 2nd, March 2nd, and so on.

    Seconds has a calendar sense as well as a clock sense: the second day in every month. Counting those dated slots gives a dozen, while stopwatch arithmetic chases a unit the puzzle never meant.

  18. 18. I have a face but no eyes and hands but no arms, and numbers live all around my edge. What am I? Medium

    Show answer

    A clock.

    Body words arrive with their function stripped away: a face that cannot see, pointers called hands that cannot grip. One household object borrows both and keeps its numbers in a ring.

  19. 19. Which number sounds like it already had dinner? Easy

    Show answer

    Eight. It sounds just like 'ate'.

    Say the number out loud and you have spoken a past tense verb about eating, which is all the dinner talk in the question was there to push you toward.

  20. 20. Cut me in half and I become nothing at all. What number am I? Medium

    Need a hint?

    Cut sideways, not up and down.

    Show answer

    8. Slice it across the middle and you get two zeros.

    Slice the drawn figure across its waist and the ink parts into two closed rings. A ring standing alone is the mark we use for nothing, which is what the card promises.

  21. 21. Ten birds are sitting in a tree and half of them fly away. How many are left? Easy

    Most people first say: None, they all fly off

    Show answer

    5, because half of 10 is 5.

    A trick is what solvers hunt for here, and this card is not hiding one. Half of an even flock divides clean, so the ones that stay match the ones that go.

  22. 22. Which number has exactly the same number of letters as its value? Medium

    Need a hint?

    Spell some small numbers and count the letters.

    Show answer

    Four. F-O-U-R is 4 letters long.

    Write each small number as a word and count its letters, then hold that letter count against the amount the word names. One word lands on the same figure twice.

  23. 23. What did the zero say to the eight? Medium

    Need a hint?

    Look at the middle of the 8.

    Show answer

    Nice belt!

    The round digit has an empty middle while the other carries a pinch across it, sitting exactly where a belt would go.

  24. 24. How many apples grow on an apple tree? Medium

    Most people first say: Depends on the tree

    Need a hint?

    It's a trick. Where else would they grow?

    Show answer

    All of them. Every apple grows on a tree!

    A how many opening promises a countable figure, but the sentence quietly restricts itself to one kind of fruit and one kind of plant. Every piece of that fruit starts on such a plant, so the share is total.

  25. 25. What's a math teacher's favorite season of the year? Medium

    Show answer

    SUM-mer.

    One season name carries a short addition word inside its spelling, and the pun works because a teacher of arithmetic would claim that word. Nothing about weather or holidays matters.

  26. 26. I'm a coin, and two of me together make ten cents. What am I? Easy

    Most people first say: A dime

    Need a hint?

    Half of ten cents.

    Show answer

    A nickel. Each one is worth 5 cents.

    A dime reaches ten cents on its own, which is why it comes up first and why it fails. The card asks for two identical coins, so each one has to carry half the total.

  27. 27. You bake 6 cookies, eat 2, and give 2 to a friend. How many cookies are left? Easy

    Show answer

    2

    Two separate departures, not one. Many solvers subtract the eaten pair, land on four, and forget the pair handed over. Both batches leave the plate, so the subtraction happens twice.

  28. 28. What is double of half of 10? Easy

    Show answer

    10

    Halving and doubling undo each other, so the round trip hands back whatever number it started from.

  29. 29. Sam is 8 and his sister is half his age. When Sam turns 10, how old will his sister be? Medium

    Show answer

    6

    She's 4 now, which is 4 years younger. She'll always be 4 years behind, so she'll be 6.

  30. 30. You have ten fingers. If you don't count the thumbs, how many fingers are left? Easy

    Show answer

    8

    The card counts all ten as fingers and then sets the thumbs aside, and a thumb sits on each hand, so two leave the count and eight stay. Dropping a single thumb is where nine comes from.

  31. 31. If yesterday was Monday, what day is tomorrow? Medium

    Show answer

    Wednesday

    Two steps forward from the day named, not one: yesterday fixes today first, and only then does tomorrow land further along the week.

  32. 32. What is seven plus seven divided by seven? Careful: do the division first! Medium

    Most people first say: Just two

    Show answer

    8

    Two sevens sitting next to each other beg to be added, yet division outranks addition. Handle the sevens on the right first, watch them shrink to one, and add that to the leading seven.

  33. 33. Take the number of days in a week and add the number of legs on a cat. What do you get? Easy

    Show answer

    11

    Each half of this card arrives as a description, so turn both into digits before adding: a full week counts seven days, and a cat stands on four paws.

  34. 34. Count by fives: 5, 10, 15... what comes next? Easy

    Show answer

    20

    The gap between each pair of listed numbers stays fixed, so find that step once and add it to the last one shown. Skip counting is really repeated addition with the middle ground left out.

  35. 35. How many corners does a cube have? Picture a dice in your hand. Medium

    Most people first say: Six corners

    Show answer

    8

    Corners is the word to hold on to, since a dice offers panels to count as well. Every meeting point where three flat panels run together counts as one, and the panel total never enters it.

  36. 36. A square is also a rectangle. Medium

    Show answer

    True.

    A rectangle needs four right angles, and a square has them. It's just a rectangle whose sides all match.

  37. 37. How many months of the year have 28 days in them? Medium

    Most people first say: Only February

    Show answer

    All twelve of them. Every month has at least 28 days.

    At least that many is all the phrasing claims, though solvers hear exactly. Every calendar block reaches the twenty eighth before it ends, so the shortest one sets the floor and the rest clear it easily.

  38. 38. I'm an odd number. Take away one letter and I turn even. What number am I? Medium

    Show answer

    Seven. Take away the s and you get 'even'.

    Even is the word doing the trick, since seven really is an odd number. Strike the opening letter off its written name and the four letters left spell the other group.

  39. 39. I have 6 straight sides and 6 corners. What shape am I? Easy

    Show answer

    A hexagon.

    Nothing here needs a ruler or a drawing. The count in the clue is already the name: hex stands for six, so six sides and six corners hand you the word.

  40. 40. A pizza is cut into 4 equal slices and you eat just 1. How much of the pizza is left? Easy

    Show answer

    Three quarters.

    The card asks how much of the pizza is left, which is a request for a fraction. Four equal pieces make each one a quarter, so eating one leaves the other three sitting there.

  41. 41. You cut a cookie in half, then cut one of those halves in half again. What is that smallest piece called? Easy

    Show answer

    A quarter.

    Two cuts in a row shrink the piece twice over, and the card wants what that piece is called. Half of a half is one of four equal parts, which is the word it is after.

  42. 42. Count by tens: 70, 80, 90... what number comes next? Easy

    Show answer

    100.

    Each printed value climbs by the same ten, and the next climb crosses into a new column. Watch for that crossing: ninety plus ten empties the tens place and opens a hundreds one.

  43. 43. The big hand on a clock goes only halfway around. How many minutes is that? Medium

    Show answer

    30 minutes.

    Knowing which pointer is the long one settles it: the long one sweeps a whole circle in an hour, and an hour holds sixty of the units being asked for. Halfway is therefore half of sixty.

  44. 44. One side of a domino shows 4 dots and the other side shows 3 dots. How many dots in all? Easy

    Show answer

    7 dots.

    The card hands you both counts already, and in all asks for them joined rather than compared. Hold four in your head and count on three, or reach for the number fact that pairs them at seven.

  45. 45. You carry a carton of 12 eggs, drop it, and exactly 3 crack. How many eggs are still whole? Easy

    Show answer

    9 eggs.

    Whole is the word the question grades you on, and a cracked egg is still an egg in the box. Take the broken ones off the dozen and count what keeps its shell.

  46. 46. A spider has 8 legs. How many legs do two spiders have altogether? Easy

    Show answer

    16 legs.

    Two identical creatures make this a doubling card. Eight and eight is one of the number facts a kid keeps ready, and it answers the question in a single move.

  47. 47. You're running a race and you zoom past the runner in second place. What place are you in now? Medium

    Most people first say: First place

    Show answer

    Second place. You took their spot, not first.

    The leader never appears in this sentence at all. Overtaking swaps you with the person you pass, and the person passed here is the runner sitting behind the front.

  48. 48. Add me to 10 and the 10 doesn't change one bit. What number am I? Easy

    Most people first say: Just one

    Show answer

    Zero. Adding zero changes nothing.

    Addition moves a total every time except once. The amount that has nothing to hand over is the one that leaves ten standing, while the do nothing number of the times tables adds a whole unit here.

  49. 49. There are 3 bicycles parked in a row. How many wheels are there in total? Easy

    Show answer

    6 wheels. Each bike has 2.

    Ticking off wheels one by one is the slow road, and it is easy to lose your place. Two per frame is the fact to hold, so three hops of two land on the total.

  50. 50. The baker hands you a dozen muffins. How many muffins is that? Easy

    Show answer

    12 muffins.

    Dozen is a trade word standing in for a number, the way a pair stands in for two. The card hands you the word and asks for the figure behind it, so this is a vocabulary question.

  51. 51. I'm the very biggest number you can write using just one single digit. What number am I? Easy

    Most people first say: Ten itself

    Show answer

    9.

    Ten feels like the winner until you look at how it is written, because it takes two marks to put down. One digit means one mark, and the marks stop at the top of the count.

  52. 52. I'm thinking of a number. Double it and you land right on a dozen. What number am I? Medium

    Show answer

    6, because 6 doubled is 12, and a dozen is 12.

    The instruction runs backwards here: you are told what doubling produces and asked for the starting value. Twelve is the total once the count word is read, so halve it and stop.

  53. 53. Multiply me by myself and I turn into 9. What number am I? Medium

    Most people first say: Four and a half

    Show answer

    3, because 3 times 3 is 9.

    Myself ties both factors to the same value, so the search runs through the times tables looking for a row that lands on nine. Halving belongs to addition cards and misses here.

  54. 54. A shape has 5 straight sides and 5 corners. What do we call it? Medium

    Most people first say: A hexagon

    Show answer

    A pentagon.

    A hexagon is the neighbour to rule out here, since it carries one more edge than the clue allows. A closed figure with straight sides has as many corners as edges, so five of each names a single family.

  55. 55. Why is the number 6 always so scared of the number 7? Hard

    Need a hint?

    Count upward from seven out loud.

    Show answer

    Because 7 8 9, which sounds like seven ate nine.

    Read the three digits aloud in a row: the middle one stops being a quantity and becomes the word for having swallowed something, which leaves the last digit as the meal.

  56. 56. You hold two coins that add up to 30 cents, and one of them is not a nickel. What are the two coins? Hard

    Most people first say: No such pair exists

    Need a hint?

    Only one of the two is ruled out.

    Show answer

    A quarter and a nickel. The quarter is the one that isn't a nickel.

    Only one coin is placed under the restriction, yet solvers apply it to both and declare the total impossible. Read it as a statement about a single coin and the pair assembles itself at once.

  57. 57. A farmer has 17 sheep, and all but 9 wander off. How many sheep are left? Hard

    Most people first say: Eight sheep

    Need a hint?

    But here means except, not minus.

    Show answer

    9 sheep.

    All but nine is a phrase naming the survivors, not an amount to remove. Treat it as everything except those nine and the subtraction you reached for never happens.

  58. 58. What do you call a number that just can't sit still and keeps roaming around? Hard

    Need a hint?

    Say roaming quickly and hear another word.

    Show answer

    A Roman numeral.

    Drop the g from the wandering word and what is left sounds like the name of an ancient numbering system. You have to hear it, since the two spellings never match on the page.

  59. 59. When you spell it out, this number has all its letters in alphabetical order. Which number is it? Hard

    Need a hint?

    Check the spelling of each multiple of ten.

    Show answer

    40, spelled forty. F, O, R, T, Y climb in order.

    Alphabetical order is a test on the written word, not on the size of the number, so write each candidate out and walk its letters from first to last. Only one climbs without a step backwards.

  60. 60. Follow the doubling: 1, 2, 4, 8, 16... what number comes next? Hard

    Most people first say: Twenty four

    Need a hint?

    Ask what you did to get sixteen.

    Show answer

    32.

    The gaps here grow, which rules out a run built on a constant step. Every step after the first doubles what came before, so the rule is a multiplier and the next term keeps it going.

  61. 61. Here's a sneaky pattern: 1, 1, 2, 3, 5, 8... what number comes next? Hard

    Most people first say: Eleven next

    Need a hint?

    Add the last two numbers you see.

    Show answer

    13.

    Line up the gaps and they run 0, 1, 1, 2, 3, so no single step holds across the row. From the third entry on, each one is the two before it added together, and that pairing carries the run forward.

  62. 62. If a rooster sits on the very top of a barn roof and lays an egg, which way does the egg roll? Hard

    Most people first say: Down the sloping side

    Need a hint?

    Which bird in the yard lays eggs?

    Show answer

    Neither way. Roosters don't lay eggs, only hens do.

    Check the bird before the geometry. A rooster is the male bird, and an egg would have to come from a hen, so the roof slope never gets to matter.

  63. 63. I'm a two-digit number. My tens digit is double my ones digit, and my two digits add up to 6. What am I? Hard

    Most people first say: Twenty four

    Need a hint?

    List pairs adding to six, then check doubling.

    Show answer

    42.

    Reversing the digits keeps the total at six, so the swapped version passes one test and fails the other: doubling runs one way only, putting the bigger digit in the tens place.

  64. 64. Find me: I'm an even number between 10 and 20, and my two digits add up to 5. What number am I? Hard

    Most people first say: The number fifteen

    Need a hint?

    Start with the numbers in the teens.

    Show answer

    14.

    The five in the clue is a total for the two digits, not a digit to hunt for, which is how an odd teen sneaks in. Keeping only the even numbers between ten and twenty leaves four, and the digit sum picks one.

  65. 65. Two single-digit numbers multiply to make 12 and add up to make 7. Which two numbers are they? Hard

    Most people first say: Two and six

    Need a hint?

    Write the pairs that multiply to twelve.

    Show answer

    3 and 4.

    Only two pairs of single digits multiply to twelve, so start from the product and test each pair against the required total. The search is short when you pick the tighter condition first.

  66. 66. In the classroom I measure your lines, and I'm also a word that means king. What am I? Hard

    Need a hint?

    One object, one kind of leader, same word.

    Show answer

    A ruler.

    Watch the phrase a word that means king: the card asks for a label, not a second object, so both halves have to land on the same name. That signal is what keeps a crown out of the running.

  67. 67. Add up every number from 1 to 5. What total do you reach? Hard

    Need a hint?

    Match the smallest with the largest first.

    Show answer

    15.

    This is a chain sum with a shortcut hiding in it. The outside two make six, the next two make six as well, and the middle value rides along on its own.

  68. 68. I'm a sneaky number. Multiply me by any number at all, big or small, and the answer is always me. What number am I? Hard

    Most people first say: One every time

    Need a hint?

    Which number makes any group vanish?

    Show answer

    0.

    One is the number kids name when a card promises nothing will change, and it fails here because it hands the group straight back. Multiplying counts copies, so asking for none leaves an empty pile.

  69. 69. A palindrome number reads the same forwards and backwards. What's the first one you reach after 99? Hard

    Most people first say: One hundred eleven

    Need a hint?

    Count up from 99 and test each.

    Show answer

    101.

    Matching front to back is the test, and the hunt starts at the first value above the one given. Climb one step at a time and the earliest match arrives long before the tidy looking triple.

  70. 70. How many times can you subtract 2 from the number 10? Hard

    Most people first say: Five times

    Need a hint?

    Notice what you subtract from the second time.

    Once, because after that you're subtracting from 8, not from 10.

    Keep subtracting and you are soon taking two from eight, then from six, which is not what the card named. The question pins the starting pile, and after one step that pile is a different size.

  71. 71. There are 5 fish swimming in a bowl and 2 of them drown. How many fish are left? Hard

    Most people first say: Three fish

    Need a hint?

    Ask whether a fish can drown at all.

    Show answer

    5 fish. Fish breathe underwater, so they can't drown.

    Gills pull oxygen straight out of the water, so a mouthful of it is ordinary for a fish. The card offers a subtraction that cannot take place, and the bowl keeps everything it started with.

  72. 72. In Roman numerals, the letter X stands for which number? Hard

    Need a hint?

    On a clock face marked with letters, look at ten.

    Show answer

    10.

    The value here is remembered, not worked out: in Roman numerals each mark carries its own amount, with no columns of tens and ones to read off. A clock face with letter hours gives an everyday place to check one.

  73. 73. Add any two odd numbers together. Is the answer going to be odd or even? Hard

    Most people first say: Always odd

    Need a hint?

    Two leftovers can pair up with each other.

    Show answer

    Even.

    An odd amount is a run of pairs with one spare left over, and that spare is the whole story. Bring two of them together and the spares find each other, so the heap lines up in twos.

  74. 74. Today is Friday the 13th. What was the date on the Friday exactly one week before? Hard

    Need a hint?

    How many dates does one week cover?

    Show answer

    The 6th.

    Counting back one date at a time gets there, though a slip is easy. Weekday names repeat on a seven day cycle, so the same weekday sits exactly seven dates earlier.

  75. 75. You split 100 stickers evenly among 4 friends. How many does each friend get? Hard

    Need a hint?

    Think of quarters of a dollar.

    Show answer

    25 stickers.

    Sharing evenly is division dressed as a story, and a hundred splits into four friendly heaps. Quarter the hundred the way you would quarter a dollar, since both come apart into equal chunks of the same size.

  76. 76. Which is worth more money: 100 pennies or 10 dimes? Hard

    Most people first say: The hundred pennies

    Need a hint?

    Turn both piles into cents and compare.

    Show answer

    Neither. Both add up to exactly one dollar.

    Which is worth more invites a winner, yet nothing promises one exists. Convert both piles into the same unit and they land on an identical value, so the comparison closes with a tie.

  77. 77. I'm a two-digit number made of two round digits, and I look the same when you flip me upside down. What am I? Hard

    Need a hint?

    Which digits look unchanged after a flip?

    Show answer

    88.

    Six and nine trade places when the page turns, so a round digit only comes back if its partner catches it. Eight is the mark that returns as itself, which is why a pair of eights reads the same either way round.

  78. 78. If one dozen is 12, how many is double a dozen? Hard

    Need a hint?

    Twelve, then twelve again.

    Show answer

    24.

    Double means a second copy of the same amount, so lay twelve beside twelve and read off the total. The count word is only a label for that value.

  79. 79. One triangle has 3 corners. How many corners do 3 triangles have altogether? Hard

    Need a hint?

    Three of the same number, added up.

    Show answer

    9 corners.

    Going corner by corner across three drawings is where kids lose track. Equal groups turn the job into a multiplication, and the shape only fixes how many points each group holds.
