4th Grade Multiplicative Comparison Test Solutions and Scoring (PDF)

1. 36 is 9 times as many as 4. (Also correct: 36 is 4 times as many as 9.)
2. \(56 = 7 \times 8\)

Scoring: 1 point for each correct part.

1. \(20 – 5 = 15\). Sofia has 15 more stickers than Mei.
2. \(20 = 4 \times 5\). Sofia has 4 times as many stickers as Mei.

Scoring: 1 point for each sentence with the correct number.

\(p = 3 \times 8 = 24\)

24 pencils

Scoring: 1 point for the equation. 1 point for 24.

\(21 = 7 \times s\). Divide: \(s = 21 \div 7 = 3\).

Check: \(7 \times 3 = 21\).

3 feet

Scoring: 1 point for the equation. 1 point for 3 feet.

\(72 = n \times 9\). Divide: \(n = 72 \div 9 = 8\).

Check: \(8 \times 9 = 72\).

8 times as much

Scoring: 1 point for the equation. 1 point for 8.

1. \(4 \times 15 = 60\). \(\$60.00\)
2. \(60 – 15 = 45\). \(\$45.00\) more

Scoring: 1 point for each part.

1. \(5 \times 6 = 30\). 30 marbles
2. \(3 \times 30 = 90\). 90 marbles
3. \(6 + 30 + 90 = 126\). 126 marbles

Scoring: 1 point for each part.

1. \(4 \times 6 = 24\). 24 stickers
2. “4 times as many” means multiply, but Ethan added 4. A multiplicative comparison needs multiplication.
3. \(24 – 6 = 18\). 18 more stickers

Scoring: 1 point for each part.

\(48 = n \times 6\). Divide: \(n = 48 \div 6 = 8\).

Check: \(8 \times 6 = 48\).

8 times as many

Scoring: 1 point for the equation. 1 point for 8.
