  1. Possible response: All the numbers in the circle are in a fact family for multiplication and division: 7 × 4 = 28; 4 × 7 = 28; 28 ÷ 4 = 7; 28 ÷ 7 = 4 and 4 × 8 = 32; 8 × 4 = 32; 32 ÷ 4 = 8; 32 ÷ 8 = 4.
  2. The circled number is the product in the multiplication sentence.
    1. 7
    2. 7
    3. 8
  4. Possible response: I thought about division, 56 ÷ 8 = 7, so the missing number is 7.

Ongoing Assessment

Use DPP item S to assess students' abilities to determine the unknown number in a multiplication or division number sentence relating three whole numbers for the last six facts [E13].

See the Letter Home for suggestions for targeted practice.
