Ongoing Assessment

Use DPP item II to assess students' abilities to determine the unknown number in a multiplication or division number sentence relating three whole numbers for the 5s and 10s [E13].

See the Letter Home for suggestions for targeted practice.

II. Fact Families: 5s and 10s

Solve each group of related facts.

    1. 3 × 5 =
    2. 15 ÷ 3 =
    3. 5 × = 15
    4. ÷ 5 = 3
    1. 5 × 10 =
    2. 50 ÷ 10 =
    3. 10 × = 50
    4. 50 ÷ 5 =
    1. 6 × 5 =
    2. ÷ 5 = 6
    3. × 6 = 30
    4. 30 ÷ 6 =
    1. × 10 = 80
    2. 80 ÷ 10 =
    3. 10 × 8 =
    4. ÷ 8 = 10
    1. 5 × = 35
    2. 35 ÷ 7 =
    3. 7 × 5 =
    4. ÷ 5 = 7
