All questions

Question 1

At the park, there are no ducks in the pond when Jake arrives. Later, 6 ducks swim into the pond, but then 6 ducks fly away. What numeral shows how many ducks are in the pond now?

  1. 6
  2. 12
  3. 1
  4. 0 (correct answer)
Explanation: Starting with 0 ducks, adding 6 ducks gives 6 total. When all 6 ducks fly away, there are 6 - 6 = 0 ducks left. The numeral 0 represents no objects. Choice A (6) forgets about the ducks flying away. Choice B (12) adds instead of subtracting. Choice C (1) makes a calculation error.

Question 2

Emma counted 7 red blocks and 5 blue blocks. She wants to write the total number of blocks she counted. Which numeral should Emma write?

  1. 11
  2. 12 (correct answer)
  3. 13
  4. 10
Explanation: Emma has 7 red blocks + 5 blue blocks = 12 total blocks. She should write the numeral 12. Choice A (11) is incorrect due to a counting error. Choice C (13) adds one too many. Choice D (10) subtracts instead of adds or miscounts.

Question 3

Which of the following shows the number thirteen?

  1. 31
  2. 13 (correct answer)
  3. 30
  4. 12
Explanation: When you write numbers in the "teens," you're combining a group of ten with some extra ones. The number thirteen means one ten plus three ones, which we write as 13 — the "1" stands for one group of ten, and the "3" tells you how many extra ones there are. That's why 13 is the correct way to show thirteen. Now look at why the others don't work. 31 uses the same two digits but in the wrong order — it shows three tens and one one, which is thirty-one, a much bigger number. Watch out for this flip! The digits look familiar, but their order changes everything. 30 shows three tens and zero ones, which is thirty, not thirteen. 12 shows one ten and two ones, which is twelve — just one less than thirteen, so it's a close neighbor but still not the right number. A helpful tip: when you hear a teen number, say it slowly. "Thir-teen" tells you it lives in the teens, so it always starts with a 1 (for the one ten) and ends with the digit that matches the first part — "thir" reminds you of 3. So thirteen becomes 1 ten+3 ones=13.1\text{ ten} + 3\text{ ones} = 13. Whenever two answers use the same digits, like 13 and 31, check the order carefully — the number on the left tells you how many tens you have!

Question 4

Which of the following shows the number six?

  1. 16
  2. 6 (correct answer)
  3. 9
  4. 7
Explanation: The number six is written with one digit: 6. When you count 1, 2, 3, 4, 5, 6, the sixth number you say looks like 6. That is why 6 is the right choice. Now look at the others. The choice 16 is "sixteen." It has two digits, a 1 and then a 6, so it is a much bigger number than six. The choice 9 is "nine," a single digit like six, but it is not the number you say when you count to six. The choice 7 is "seven," which comes right after six when you count, so it is one too many. A helpful idea: small counting numbers like six are written with just one digit. Say the number out loud and picture its symbol. That way you can spot 6 quickly and easily.

Question 5

Which of the following shows the number zero?

  1. 10
  2. 0 (correct answer)
  3. 20
  4. 12
Explanation: The number zero means none — nothing at all, like an empty hand or a plate with no cookies. The symbol that shows zero is 0, one single round shape standing all by itself. Let's see why the other choices are not zero. The choice with a 1 and then a 0 is ten. Even though it uses the 0 symbol, the 1 in front makes a whole new, bigger number — ten things, which is a lot! The choice with a 2 and then a 0 is twenty, an even bigger number that is far from nothing. The choice with a 1 and then a 2 is twelve, another big amount of things. Remember: zero stands all alone as just 0. The moment another number joins it, the amount changes into something bigger. Try holding out an empty hand for zero, then add one item at a time to feel what each number means!

Question 6

Which of the following shows the number eight?

  1. 8 (correct answer)
  2. 80
  3. 9
  4. 18
Explanation: When you're learning to recognize numbers, the key is to match the number word you hear with the correct symbol (called a numeral). Here, you're looking for the number eight. The numeral 88 is exactly how we write eight. If you count objects—like eight blocks or eight fingers—and write down how many there are, you'd write 88. That's why 8 is the number eight. Now let's look at the others. 80 is a bigger number: it has a 88 and a 00 next to it, which makes "eighty." That extra 00 changes everything—it's ten times as much as eight! 9 is the number nine, which comes right after eight when you count "…seven, eight, nine." It's close, but it's one more than eight. 18 is "eighteen," which has a 11 and an 88. The 11 in front means it's a much larger number, past ten. A helpful trick: when you're matching a number word to a numeral, count it out on your fingers or with objects first. Eight fingers matches the single symbol 88. Also watch out for the sneaky 00—numbers like 8080 can look similar but are much bigger. And remember that numbers with two digits (like 1818) are always past ten, so they can't be a small number like eight.

Question 7

Which of the following shows the number sixteen?

  1. 61
  2. 60
  3. 17
  4. 16 (correct answer)
Explanation: When you write numbers, the position of each digit matters. In a two-digit number, the digit on the left tells you how many tens you have, and the digit on the right tells you how many ones. The word "sixteen" means one group of ten plus six more, which we write as 1616 — a 11 in the tens place and a 66 in the ones place. That's why 16 correctly shows sixteen: it says "1 ten and 6 ones," and 10+6=1610 + 6 = 16. Now look at 61. This has the digits flipped, so it means "6 tens and 1 one," which is sixty-one — a much bigger number. Flipping digits changes the value, so be careful about which digit comes first! The choice 60 means "6 tens and 0 ones," which is sixty. That's not sixteen at all; it just happens to start with a 66, but sixteen needs a 66 in the ones spot, not the tens spot. The choice 17 means "1 ten and 7 ones," which is seventeen. It's close to sixteen, but one too many — remember, sixteen comes right before seventeen when you count. A helpful tip: when you hear a "-teen" number like sixteen, it always starts with a 11 (for one ten), and the second digit matches the number word — "six-teen" ends in 66. Say the number slowly and listen for the ones digit to match!

Question 8

Which of the following shows the number eleven?

  1. 1
  2. 10
  3. 11 (correct answer)
  4. 12
Explanation: When you read a number word like "eleven," your job is to match it with the correct written number, called a numeral. Reading numbers between ten and twenty can be tricky because they all use two digits, so let's slow down and count. Eleven comes right after ten. If you start at ten and count one more, you get eleven, which is written as 1111. Notice it has two ones side by side — that's a helpful picture to remember, since "eleven" has a pair of matching digits. Now let's check the choices that don't fit. The number 11 is just "one" — a single digit standing all by itself, which is far smaller than eleven. The number 1010 is "ten," which comes before eleven when you count, so it's one too few. The number 1212 is "twelve," which comes after eleven — it's one too many. Only 1111 lands exactly on eleven. A great way to build this skill is to count out loud and point to each numeral: "ten, eleven, twelve" while looking at 10,11,1210, 11, 12. When a question asks you to find a "teen" number word, remember that these numbers almost always have two digits, and saying the counting sequence in order helps you land on the right one every time.

Question 9

Which of the following shows the number twenty?

  1. 20 (correct answer)
  2. 12
  3. 21
  4. 2
Explanation: When you read a number word like "twenty," your job is to match it to the correct written number. This means paying close attention to the digits and their order, because two numbers can use the same digits but mean very different things. The word "twenty" means two groups of ten, which we write as 20. The digit 22 is in the tens place and the digit 00 is in the ones place, so 20=2 tens+0 ones20 = 2 \text{ tens} + 0 \text{ ones}. That matches "twenty" exactly. Now look at why the others don't fit. The number 12 is "twelve," which is one ten and two ones — it uses a 11 and a 22, not a 22 and a 00. The number 21 is "twenty-one," which is one more than twenty; it has an extra one in the ones place, so it's close but too big. The single digit 2 is just "two" — only two ones, with no tens at all, so it's much smaller than twenty. A helpful trick: numbers in the twenties always start with a 2, and "twenty" all by itself ends in 0 because there are no extra ones. So whenever you hear a "-ty" word like twenty, thirty, or forty, look for the number that ends in 00. Practice saying the number aloud and counting the tens and ones — that will help you spot the right match every time.

Question 10

Which of the following shows the number twelve?

  1. 21
  2. 20
  3. 13
  4. 12 (correct answer)
Explanation: The number twelve comes right after eleven when you count: ten, eleven, twelve. To write twelve, you use a 1 and then a 2, which makes 12. The 1 means one group of ten, and the 2 means two more ones—ten plus two is twelve! Let's check the ones that don't work. 13 is thirteen, the number that comes just after twelve, so it is one too many. 21 uses the same two digits but in the wrong order—that is twenty-one, which is much bigger. 20 is twenty, two full groups of ten with none left over. A tip: teen numbers start with a 1 because there is one group of ten. The second digit tells how many extra ones you have. For twelve, that second digit is 2.

Question 11

Lisa has 13 stickers. She gives 7 stickers to her brother and 4 stickers to her sister. What numeral represents how many stickers Lisa has left?

  1. 3
  2. 2 (correct answer)
  3. 4
  4. 6
Explanation: Lisa gives away 7 + 4 = 11 stickers total. Starting with 13 stickers, she has 13 - 11 = 2 stickers left. Choice A (3) subtracts only 10 instead of 11. Choice C (4) only subtracts the stickers given to her brother. Choice D (6) only subtracts 7 instead of the total 11.

Question 12

Which of the following shows the number nineteen?

  1. 91
  2. 90
  3. 20
  4. 19 (correct answer)
Explanation: Nineteen means 1 ten and 9 ones, so you write a 1 first and a 9 next. That gives you 19, the correct answer. The choice 91 uses the same two digits, but they are flipped, so it says ninety-one instead. The choice 90 is ninety, which has a 9 and a 0, not a 9 in the ones place. The choice 20 is twenty, the number that comes right after nineteen when you count, but it is not nineteen. Remember that every teen number, like seventeen, eighteen, and nineteen, starts with a 1 in front!

Question 13

Which of the following shows the number seventeen?

  1. 71
  2. 27
  3. 17 (correct answer)
  4. 18
Explanation: The number seventeen means 1 ten and 7 ones. You write the 1 first and the 7 after it, which gives you 17. Teen numbers from 13 to 19 all start with a 1 because they each have one group of ten, so listen for that hidden "ten" and put the 1 in front. Now look at the others. The choice 71 has the same digits flipped around. That puts the 7 first and the 1 after, which makes seventy-one, a much bigger number. The choice 27 starts with a 2, so it shows 2 tens and 7 ones, which reads as twenty-seven, not a teen number at all. The choice 18 is eighteen, which is one more than seventeen, so it is close but not the number you want. Only 17 shows seventeen. Try lining up a group of ten counters plus seven extras to see why the 1 comes first!

Question 14

Which of the following shows the number fourteen?

  1. 41
  2. 40
  3. 14 (correct answer)
  4. 15
Explanation: When you write a two-digit number, the order of the digits matters! Each digit has a special spot: the digit on the left tells you how many tens, and the digit on the right tells you how many ones. The number fourteen means 1 ten and 4 ones, so you write the 11 first and the 44 second, giving you 1414. Look closely at 1414: the 11 stands for one group of ten, and the 44 stands for four extra ones. Together that's 10+4=1410 + 4 = 14. That's exactly the number fourteen! Now let's check the others. The number 4141 has the digits flipped — the 44 is in the tens spot and the 11 is in the ones spot, so it reads as forty-one (40+140 + 1), not fourteen. This is the classic "flipped digits" trap, so read carefully! The number 4040 means 4 tens and 0 ones, which is forty — a much bigger number than fourteen. And 1515 means 1 ten and 5 ones, which is fifteen — that's one more than fourteen, not fourteen itself. A helpful tip: when you hear "four-teen," remember the "-teen" numbers all start with a 11 in front (like 1313, 1414, 1515). Say the number out loud and match the sound to the digits. Watch out for tricky pairs like 1414 and 4141 that use the same digits in a different order!

Question 15

Which of these shows one ten and five ones?

  1. 51
  2. 15 (correct answer)
  3. 50
  4. 14
Explanation: One ten and five ones means you take a group of ten and add five more: 10 + 5 = 15. The 1 sits in the tens place on the left, and the 5 sits in the ones place on the right. That is why 15 is correct. Now look at the other choices. In 51, the digits are flipped, so it shows five tens and one one, which is fifty-one, a much bigger number. In 50, there are five tens and zero ones, which is fifty, so it has no extra ones at all. In 14, there is one ten but only four ones, so it is one less than the number you want. A helpful tip: the tens digit always comes first, on the left, and the ones digit comes last, on the right. Check both places before you choose!
