See the Letter Home for suggestions of targeted practice.

P. Fact Families: Groups 1–4

Solve each set of related facts.

    1. 12 − = 3
    2. 9 + = 12
    3. − 3 = 9
    4. 3 + 9 =
    1. 13 − 4 =
    2. + 4 = 13
    3. − 9 = 4
    4. 4 + = 13
    1. 14 − 9 =
    2. 9 + 5 =
    3. − 5 = 9
    4. 5 + = 14
    1. 11 − 8 =
    2. 8 + = 11
    3. 11 − = 8
    4. 3 + 8 =
    1. 11 − 4 =
    2. 7 + = 11
    3. 11 − = 4
    4. 4 + = 11
    1. 15 − 6 =
    2. + 6 = 15
    3. − 9 = 6
    4. 9 + 6 =
    1. 10 − 3 =
    2. 3 + = 10
    3. 10 − = 3
    4. 7 + 3 =
    1. 9 − 6 =
    2. 6 + 3 =
    3. − 3 = 6
    4. 3 + = 9
