This DPP item provides practice with some of the fact families for the multiplication facts for the 2s, 3s, and 9s.

  1. 2 × 7 = 14, 14 ÷ 2 = 7,
    14 ÷ 7 = 2, 7 × 2 = 14
  2. 3 × 9 = 27, 27 ÷ 9 = 3,
    27 ÷ 3 = 9, 9 × 3 = 27
  3. 9 × 6 = 54, 54 ÷ 9 = 6,
    54 ÷ 6 = 9, 6 × 9 = 54
  4. 2 × 4 = 8, 4 × 2 = 8,
    8 ÷ 4 = 2, 8 ÷ 2 = 4
  5. 2 × 9 = 18, 18 ÷ 9 = 2,
    9 × 2 = 18, 18 ÷ 2 = 9
  6. 8 × 3 = 24, 24 ÷ 8 = 3,
    24 ÷ 3 = 8, 3 × 8 = 24
  7. 2 × 8 = 16, 16 ÷ 8 = 2,
    8 × 2 = 16, 16 ÷ 2 = 8
  8. 2 × 3 = 6, 6 ÷ 2 = 3,
    6 ÷ 3 = 2, 3 × 2 = 6
  9. 3 × 6 = 18, 18 ÷ 3 = 6,
    18 ÷ 6 = 3, 6 × 3 = 18
  10. 7 × 9 = 63, 63 ÷ 7 = 9,
    9 × 7 = 63, 63 ÷ 9 = 7
