Stage 5 Solving multiplication problems by using multiplication facts and repeated addition.
4 x 6 = (6 + 6) + (6 + 6) = 12 + 12 = 24
Stage 5 Solving division problems by using multiplication facts and repeated addition.
20 divided 4 = 5 because 5 + 5 10 and 10 + 10 = 20
|
Stage 6 Solving multiplication and division problems by using different strategies and known facts.
4 x 8 = 2 x 16 = 32 (doubling and halving)
9 x 6 = (10 x 6) - 6 = 54 (rounding compensating)
63 divided 7 = 9 because 9 x 7 = 63 (reversals)
|
Stage 7 Solving multiplication and division problems by using different strategies and estimating
24 x 6 = (20 x 6) + (4 x 6) (place value and partitioning)
24 x 6 = 25 x 6 - 6 (rounding and compensating)
63 divided 7 = 9 because 9 x 7 = 63 (reversals)
81 divided by 9 = 9 so 81 divided by 3 = 3 x 9 = 27
