3 x 4 = ?

Explain in your own words how multiplication and division are related.

What two inverse operations does this array represent?

• 16 ÷ 4 = 4

  4 × 4 = 16

• 12 ÷ 3 = 4

  4 × 3 = 12

• 4 + 4 + 4 + 4 = 20

  20 - 4 = 4

• I don't know

• multiplicaion

Division problems can be solved using repeated _____ .

• subtraction

• division

• addition

• multiplicaion

Which shows the correct way to solve this division equation using repeated subtraction.

20 ÷ 4 = ?

• 20 - 4 = 16

  16 - 4 = 12

  12 - 4 = 8

  8 - 4 = 4

  Therefore 20 ÷ 4 = 4

• 20 - 4 = 16

  16 - 4 = 12

  12 - 4 = 8

  8 - 4 - 4

  4 - 4 = 0

  Therefore 20 ÷ 4 = 5

• 20 - 4 = 5

• 4 + 4 + 4 + 4 + 4 = 20
