(2 pts)
Answer: 251, 308, 349
6.
Mia says 451 rounds to 400 when you round to the nearest 100, because the ones digit is 1. Is Mia right? Explain. You may draw a number line.
(3 pts)
Answer: 500. Mia is not right. Look for: 451 is between 400 and 500; the halfway point is 450; 451 is past halfway (or the tens digit is 5), so it rounds up to 500. You look at the tens digit, not the ones digit.

Scoring: Items 1–4: 1 point for each part. For item 2, give 1 point for the right symbol and 1 point for the right place. Item 5: 2 points for exactly 251, 308 and 349; 1 point if one is missing or one extra number is circled. Item 6: 3 points for "not right," 500 and a reason that uses the tens digit or the halfway point (450); 2 points for 500 with a weak reason; 1 point for "not right" only.

Reteach if needed: Week 1, Week 5. Week 1 Days 1–3 (value of each digit, three forms, comparing) and Week 1 Days 4–5 (rounding to the nearest 10 and 100 on a number line), plus Week 5 Day 2 (rounding review).

Item 6: 1 point for each correct step and 1 point for the final answer 553. Item 7: 2 points for each part; for part (b), give 2 points if your child correctly adds their own part (a) answer to 527.

Reteach if needed: Week 2, Week 3, Week 5. Week 2 Days 2–4 (adding with regrouping in the ones and tens), Week 3 Days 3–4 (subtracting with regrouping and across zeros), Week 2 Day 5 and Week 3 Day 5 (word problems, including compare problems) and Week 5 Day 1 (fixing regrouping mistakes).

18.

Show 18 as two different arrays. Write a multiplication sentence for each one.
(3 pts)
Answer: Answers vary. Look for: two correct arrays and sentences from 1 × 18, 18 × 1, 2 × 9, 9 × 2, 3 × 6, 6 × 3 (each makes 18).

Scoring: Items 1, 3, 4 and 5: 1 point for each part, or 1 point for the sentence and 1 point for the total. Item 2: 2 points for the right choice. Item 6: 3 points for two different correct arrays with sentences; 2 points for two arrays with one sentence missing; 1 point for one correct array and sentence. 2 × 9 and 9 × 2 count as two different arrays.

Reteach if needed: Week 4, Week 5. Week 4 Days 1–2 (equal groups and repeated addition), Week 4 Days 3–4 (arrays, factors and product) and Week 5 Day 4 (garden arrays).

Part 4: Facts: ×2, ×5, ×10

11 points

Write the product. Then solve the problems.

20.

You know 10 × 6 = 60. Explain how that fact helps you find 5 × 6. What is 5 × 6?
(3 pts)
Answer: 30. Look for: 5 groups is half of 10 groups, so 5 × 6 is half of 60, which is 30.

Scoring: Items 1–3: 1 point for each fact. Item 4: 2 points for 80 (1 point for a correct sentence with a slip in the product). Item 5: 3 points for 30 with a clear "half of 10 groups" reason; 2 points for 30 with a skip-counting reason only; 1 point for 30 only.

Reteach if needed: Week 6. Week 6 Days 1–3 (×2 doubles, ×10 with tens, ×5 patterns) and Week 6 Day 4 (×5 as half of ×10).
