Answer key for parents & teachers (28 questions)
  1. Two bundles of 10 = how many ones? — 20. 2 tens = 20 ones. Each bundle has 10, so 2 × 10 = 20!
  2. A box holds exactly 10 cookies. You fill 1 box. How many cookies? — 10. 1 box × 10 cookies each = 10 cookies. One box = one ten!
  3. Why do we bundle 10 ones into 1 ten? — To make counting and organizing easier. Bundling makes it EASIER to count and organize large amounts — that is the whole point!
  4. You have 7 ones. How many MORE do you need to make a ten? — 3. 7 + 3 = 10. You need 3 more ones to bundle into a ten!
  5. How is the number 10 written using tens and ones? — 1 ten, 0 ones. 10 = 1 ten and 0 ones. One full bundle, nothing left over!
  6. If you can bundle 10 crayons at a time, how many bundles can you make from 30 crayons? — 3. 30 ÷ 10 = 3. You can make 3 bundles (3 tens) from 30 crayons!
  7. What happens to the value when you go from 9 ones to 10? — You can form a new ten. When you reach 10 ones, you bundle them into a NEW TEN — this is how place value works!
  8. Which picture shows "1 ten and 0 ones"? — A bundle of 10. A bundle (box) of 10 items shows 1 ten and 0 ones = the number 10!
  9. How many ones are in 3 tens? — 30. 3 tens = 30 ones. Each ten contains 10 ones, so 3 × 10 = 30!
  10. A ten-rod (a stick of 10 blocks) represents which number? — 10. A ten-rod (or "long") always represents the number 10 — one group of ten!
  11. The number 11 has how many tens and how many ones? — 1 ten, 1 one. 11 = 1 ten + 1 one. One ten and one extra one!
  12. Which of these is NOT a teen number (11–19)? — 20. 20 is NOT a teen number — it is two full tens with no extra ones!
  13. I am a teen number with 1 ten and 6 ones. What am I? — 16. 1 ten + 6 ones = 16 (sixteen)!
  14. Which number has the MOST ones: 14, 17, 12, 19? — 19. 19 = 1 ten + 9 ones. Nine ones is the most!
  15. Between 11 and 19, all numbers share what feature? — They all have exactly 1 ten. Every number from 11 to 19 has exactly 1 ten — that is what makes them "teen" numbers!
  16. You have 1 box of 10 pencils and 5 loose pencils. What number is that? — 15. 1 box (1 ten) + 5 loose (5 ones) = 15 (fifteen)!
  17. What do the numbers 13 and 17 have in common? — Same tens digit. Both 13 and 17 have the digit "1" in the tens place — they each have 1 ten!
  18. 1 ten + ___ ones = 18. What is the missing number? — 8. 1 ten + 8 ones = 18. The missing number is 8!
  19. Which shows 1 ten and 4 ones using blocks? (📦=ten, ✏️=one) — 📦✏️✏️✏️✏️. 📦✏️✏️✏️✏️ = 1 ten-box + 4 single pencils = 14!
  20. What is the LARGEST teen number? — 19. 19 is the largest teen number. After 19 comes 20 (two tens)!
  21. What number is made by 6 tens and 3 ones? — 63. 6 tens + 3 ones = 60 + 3 = 63.
  22. Break apart 45. Choose the correct answer. — 40 + 5 (4 tens and 5 ones). 45 = 40 + 5 = 4 tens and 5 ones. The LEFT digit is tens, the RIGHT digit is ones.
  23. Which is larger: 5 tens or 5 ones? — 5 tens (50). 5 tens = 50, but 5 ones = 5. Fifty is much larger than five!
  24. What number comes right after 39? — 40. 39 = 3 tens and 9 ones. Adding 1 more one fills the ones up → becomes 4 tens and 0 ones = 40!
  25. A box has 3 groups of 10 crayons and 7 extra crayons. How many crayons total? — 37. 3 groups of 10 = 30. Plus 7 more = 37 crayons total. That is 3 tens and 7 ones!
  26. In the number 58, which digit is in the ONES place? — 8. In 58, the RIGHT digit is 8. The ones place is always the right-most digit in a two-digit number.
  27. What is 40 + 9? — 49. 40 = 4 tens, 9 = 9 ones. Together: 4 tens and 9 ones = 49!
  28. How many ones are in the number 70? — 0. 70 = 7 tens and 0 ones. The ones digit is 0!
