WALT solve multiplication using rounding and compensating.
48 x 5 =240
50 x 5 =250
2 x 5 =10
250 - 10 =240
----------------------------------------------------------------------------------------------------------------------------------
WALT use doubling and halving to solve multiplication problems.
48 x 5 =
24 x 10 = 240
----------------------------------------------------------------------------------------------------------------------------------
WALT use family of facts to solve division problems.
6 x 7 = 42
7 x 6 = 42
42 / 6 = 7
42 / 7 = 6
I can also use reversing - by turning a division problem into a multiplication problem.
27 / 9 =
I can change it to 9 x __ = 27
9 x 3 = 27
