Answer key for parents & teachers (32 questions)
  1. Which unit fraction is the LARGEST? โ€” 1/2. Larger denominator = smaller piece. 1/2 has the smallest denominator โ†’ it is the largest unit fraction!
  2. Which unit fraction is the SMALLEST? โ€” 1/8. 1/8 has the largest denominator โ†’ smallest piece โ†’ smallest fraction!
  3. Why does a larger denominator mean a smaller piece? โ€” More equal cuts means each cut is smaller. When you cut a whole into MORE equal pieces, each piece is SMALLER!
  4. Is 1/4 > 1/6? โ€” Yes, 1/4 has fewer cuts so each piece is bigger. Yes! Smaller denominator = fewer cuts = bigger pieces. 1/4 > 1/6!
  5. True or False: 1/6 is greater than 1/3. โ€” False โ€” 1/6 < 1/3. False! 1/3 > 1/6 because thirds are bigger slices than sixths!
  6. Which shows the correct comparison of unit fractions? โ€” 1/2 > 1/3. 1/2 > 1/3 because halves are bigger than thirds!
  7. How many 1/6 pieces make a whole? โ€” 6. 6 pieces of 1/6 = 6/6 = 1 whole!
  8. On a number line divided into 8 parts, what fraction is 3 jumps from 0? โ€” 3/8. 3 jumps of 1/8 each = 3/8!
  9. On a number line, which fraction is CLOSER to 1: 5/6 or 3/6? โ€” 5/6. 5/6 needs just 1/6 more to reach 1. 3/6 needs 3/6 more. 5/6 is closer to 1!
  10. On a number line from 0 to 1 in fourths, what is between 2/4 and 4/4? โ€” 3/4. 2/4, 3/4, 4/4. The fraction between 2/4 and 4/4 is 3/4!
  11. On a number line in thirds from 0 to 1, what is 2/3 + 1/3? โ€” 3/3 = 1. 2/3 + 1/3 = 3/3 = 1. Two jumps plus one more lands at 1 on the number line!
  12. A number line is divided into 6 equal spaces from 0 to 1. Which mark is 2/6? โ€” Second mark after 0. 2/6 is at the SECOND mark โ€” two jumps of 1/6 from 0!
  13. On a number line in fourths, which fraction is between 1/4 and 3/4? โ€” 2/4. 1/4, 2/4, 3/4 โ€” the fraction between is 2/4!
  14. Which statement about 0/3 is correct? โ€” It equals 0. 0/3 = 0. Zero pieces of a whole = zero โ€” the starting point on the number line!
  15. Amy walks 3/4 of the way to school. She still has ___ to walk. โ€” 1/4. 4/4 โˆ’ 3/4 = 1/4. She has 1/4 of the way left!
  16. Is 1/4 equivalent to 2/8? โ€” Yes. 1/4 ร— 2/2 = 2/8. Cross-check: 1ร—8 = 8 and 4ร—2 = 8. YES, equivalent!
  17. Which fraction is equivalent to 2/6? โ€” 1/3. 2/6 รท 2/2 = 1/3. Both equal one-third!
  18. Are 3/6 and 4/8 equivalent? โ€” Yes โ€” both equal 1/2. 3/6 = 1/2 and 4/8 = 1/2. Both simplify to 1/2 โ€” equivalent!
  19. Cross-multiply to check: are 2/3 and 4/6 equivalent? โ€” Yes, 2ร—6 = 12 = 3ร—4. 2ร—6 = 12 and 3ร—4 = 12. Equal cross-products mean they ARE equivalent!
  20. Which fraction is NOT equivalent to 1/2? โ€” 3/8. 3/8: cross-multiply: 1ร—8=8, 2ร—3=6. 8 โ‰  6, so 3/8 is NOT equivalent to 1/2!
  21. Fill in: 1/3 = __/9 โ€” 3. 1/3 ร— 3/3 = 3/9. The missing number is 3!
  22. Fill in: 2/5 = 4/__ โ€” 10. Multiply numerator by 2: 2ร—2=4. Multiply denominator by 2: 5ร—2=10. Missing number is 10!
  23. True or False: You can create equivalent fractions by multiplying the numerator and denominator by different numbers. โ€” False โ€” you must use the SAME number. False! You MUST multiply (or divide) by the SAME non-zero number to create equivalent fractions!
  24. Is 3/8 greater than or less than 1/2? โ€” Less than โ€” 3/8 < 4/8 = 1/2. 1/2 = 4/8. Since 3 < 4, we have 3/8 < 4/8 = 1/2!
  25. Is 5/6 greater than or less than 1/2? โ€” Greater โ€” 5 > 3 (which is half of 6). Half of 6 is 3. Since 5 > 3, we have 5/6 > 1/2!
  26. Compare 3/8 and 5/6 using 1/2 as benchmark. What is the result? โ€” 3/8 < 5/6. 3/8 < 1/2 (since 3 < 4). 5/6 > 1/2 (since 5 > 3). Therefore 3/8 < 1/2 < 5/6!
  27. Compare 2/5 and 2/8. โ€” 2/5 > 2/8. Same numerator (2): smaller denominator = bigger fraction. 2/5 > 2/8!
  28. Order from least to greatest: 1/4, 3/4, 1/2. โ€” 1/4, 1/2, 3/4. 1/4 = 2/8; 1/2 = 4/8; 3/4 = 6/8. Order: 1/4 < 1/2 < 3/4!
  29. Is 2/3 greater than 1/2? โ€” Yes โ€” 2 > half of 3 (which is 1.5, and 2 > 1.5). Half of 3 is 1.5. Since 2 > 1.5, we have 2/3 > 1/2!
  30. Tom ate 3/5 of his sandwich. Jerry ate 4/5. Who ate more? โ€” Jerry (4/5). Same denominator (5): 4 > 3 so 4/5 > 3/5. Jerry ate more!
  31. Which fraction is exactly equal to 1/2? (Same value, different look) โ€” 3/6. 3/6 = 1/2. Cross-check: 1ร—6 = 6 and 2ร—3 = 6. Equal!
  32. Which fraction falls BETWEEN 1/2 and 1 on the number line? โ€” 3/4. 3/4 = 0.75, which is between 0.5 (1/2) and 1. So 3/4 is between 1/2 and 1!
