Day 1: Equivalent fractions and visual models | Answers

  1. 1. 8/12
  2. 2. 20/24
  3. 3. 2/3
  4. 4. 3/4
  5. 5. Yes, both equal 2/5
  6. 6. 12
  7. 7. Two quarters shade the same amount as one half
  8. 8. 12/25
  9. 9. Examples: 14/16 and 21/24
  10. 10. The denominator would become zero, which is undefined.

Check reasoning as well as answers. If fewer than 8 of 10 are correct, reteach and assign new parallel examples.

Day 2: Compare and order fractions | Answers

  1. 1. 3/8 < 5/8
  2. 2. 2/3 < 3/4
  3. 3. 7/10 > 2/5
  4. 4. 3/8, 1/2, 5/8
  5. 5. 5/12 < 1/2
  6. 6. Example: 1/2
  7. 7. 7/8
  8. 8. With equal numerators, fifths are larger portions than sevenths
  9. 9. 2/3, 3/4, 5/6
  10. 10. 11/12 > 13/15 because 165 > 156.

Check reasoning as well as answers. If fewer than 8 of 10 are correct, reteach and assign new parallel examples.

Day 3: Add and subtract fractions with like denominators | Answers

  1. 1. 6/9 = 2/3
  2. 2. 4/8 = 1/2
  3. 3. 11/12
  4. 4. 7/15
  5. 5. 8/10 = 4/5
  6. 6. 4/16 = 1/4
  7. 7. 5/6
  8. 8. 6/20 = 3/10
  9. 9. 5/8 m
  10. 10. 6

Check reasoning as well as answers. If fewer than 8 of 10 are correct, reteach and assign new parallel examples.

Day 4: Tenths, hundredths and decimal equivalents | Answers

  1. 1. 0.4
  2. 2. 0.27
  3. 3. 83/100
  4. 4. 50/100
  5. 5. 0.47 < 0.5
  6. 6. 0.09 < 0.1
  7. 7. 0.25, 0.3, 0.32
  8. 8. 0.64
  9. 9. 75/100 m
  10. 10. 70/100 = 7/10; the trailing zero changes no value.

Check reasoning as well as answers. If fewer than 8 of 10 are correct, reteach and assign new parallel examples.

Day 5: Independent unit assessment | Answers

  1. 1. 2/3
  2. 2. 15
  3. 3. 7/8 > 5/6
  4. 4. 3/10, 2/5, 1/2

  8. 8. 7/8 km
  9. 9. 0.65 liter by 0.05 liter
  10. 10. Three of six equal parts cover half of the same whole.

Assessment: 10 items, suggested checkpoint of 8 correct independently with clear explanations for items 8 through 10. Record errors, reteach, and reassess with different numbers.

Pacing and next steps

This is one five-day unit, not full-year mastery proof. Keep a private record of date, independence, score, remediation, and follow-up check. The downloadable fillable PDF, additional spiral review, and cumulative quarter assessment still require production.
