About this exercise
Each round shows an equation like 4 × ? = 28 or ? × 6 = 42. You fill in the missing factor. The exercise practises both multiplication and division as inverse operations.
How to practise
Ask: "How many times do I take this number to reach the product?" Division helps: 28 ÷ 4 = 7, so 4 × 7 = 28.
