TIMS Bit

Use this DPP item to provide practice with the fact families for some of the multiplication and division facts by finding the unknown in a number sentence.

  1. n = 5
    7 × 5 = 35
    35 ÷ 7 = 5
    35 ÷ 5 = 7
  2. n = 6
    12 ÷ 2 = 6
    2 × 6 = 12
    6 × 2 = 12
  3. n = 3
    12 ÷ 4 = 3
    4 × 3 = 12
    3 × 4 = 12
  4. n = 4
    4 × 8 = 32
    32 ÷ 8 = 4
    32 ÷ 4 = 8
  5. n = 7
    7 × 9 = 63
    63 ÷ 7 = 9
    63 ÷ 9 = 7
  6. n = 6
    6 × 6 = 36
  7. n = 8
    40 ÷ 5 = 8
    8 × 5 = 40
    5 × 8 = 40
  8. n = 7
    49 ÷ 7 = 7
  9. n = 5
    30 ÷ 6 = 5
    6 × 5 = 30
    5 × 6 = 30
  10. n = 6
    8 × 6 = 48
    48 ÷ 6 = 8
    48 ÷ 8 = 6

A. Facts Practice

Find the number for n that will make each number sentence true. Then write the other number sentences in that fact family.

  1. n × 7 = 35
  2. 12 ÷ n = 2
  3. 12 ÷ n = 4
  4. 8 × n = 32
  5. 9 × n = 63
  6. 36 ÷ n = 6
  7. 40 ÷ n = 5
  8. 7 × n = 49
  9. 30 ÷ n = 6
  10. n × 8 = 48
