Question 2

Jenna knows that 9 × 4 = 36 and 9 × 3 = 27. Which statement correctly uses these facts to find 9 × 7 and also explains why the method works?

Accepted Answer

Since 7 = 4 + 3, add the two products: 36 + 27 = 63, so 9 × 7 = 63.

Answer

Add the two products and then add one more 9: 36 + 27 + 9 = 72, so 9 × 7 = 72.

Answer

Subtract the smaller product from the larger: 36 – 27 = 9, so 9 × 7 = 9.

Answer

Multiply the two products together: 36 × 27 = 972, so 9 × 7 = 972.

Question 3

Maya knows that 6 × 4 = 24 and 6 × 3 = 18. Which statement shows the correct way to use these facts to find 6 × 7, and also describes the general rule she is using?

Accepted Answer

6 × 7 = 6 × 4 + 6 × 3 = 24 + 18 = 42

Answer

6 × 7 = 6 × 4 + 7 = 24 + 7 = 31

Answer

6 × 7 = (6 × 4) × (6 × 3) = 24 × 18 = 432

Answer

6 × 7 = 6 × 4 – 6 × 3 = 24 – 18 = 6
