Grade 4 Mathematics Unit 2 | Teacher Guide
Parent and teacher reference. Keep answers separate from student work. Use fraction strips, equal-size drawings and number lines to explain concepts. Grade independent work before coaching.
Day 1: Equivalent fractions and visual models | Answers
- 1. 8/12
- 2. 20/24
- 3. 2/3
- 4. 3/4
- 5. Yes, both equal 2/5
- 6. 12
- 7. Two quarters shade the same amount as one half
- 8. 12/25
- 9. Examples: 14/16 and 21/24
- 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. 3/8 < 5/8
- 2. 2/3 < 3/4
- 3. 7/10 > 2/5
- 4. 3/8, 1/2, 5/8
- 5. 5/12 < 1/2
- 6. Example: 1/2
- 7. 7/8
- 8. With equal numerators, fifths are larger portions than sevenths
- 9. 2/3, 3/4, 5/6
- 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. 6/9 = 2/3
- 2. 4/8 = 1/2
- 3. 11/12
- 4. 7/15
- 5. 8/10 = 4/5
- 6. 4/16 = 1/4
- 7. 5/6
- 8. 6/20 = 3/10
- 9. 5/8 m
- 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. 0.4
- 2. 0.27
- 3. 83/100
- 4. 50/100
- 5. 0.47 < 0.5
- 6. 0.09 < 0.1
- 7. 0.25, 0.3, 0.32
- 8. 0.64
- 9. 75/100 m
- 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. 2/3
- 2. 15
- 3. 7/8 > 5/6
- 4. 3/10, 2/5, 1/2
- 5. 7/9
- 6. 6/12 = 1/2
- 7. 48/100
- 8. 7/8 km
- 9. 0.65 liter by 0.05 liter
- 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.
