Practice your times tables for 10-15 mins on this site before going on Maths Whizz.

AA-Solving mathematical problems by using the best strategy.

First practise part-whole strategies to solve these problems. (Jumping through tens)

e.g. 49 + 8 = (49 + 1) + (8 - 1) = 50 + 7 = 57

or 49 + 28 = (49 + 1) + (28 - 1) = 50 + 27 = 77

or 53 - 7 = 53 - 3 - 4 = 50 - 4 = 46

or 53 - 27 = 53 - 3 - 24 = 50 - 24 = 26 or 53 - 27 = 53 - 20 = 33 - 7 = 33 - 3 - 4 = 30 - 4 = 26
