Think! What different methods can you use to work out multiplication sums? Sometimes we dont know the answer to a multiplication question…

So 6 x 4 = 4 + 4 + 4 + 4 + 4 + 4 4 x 6 = 6 + 6 + 6 + 6 One way of tackling a multiplication question is by using repeated addition… +4 +6

So 3 x 9 = OR 9 x 3 = What repeated addition sums could you do to work out this multiplication sum? Have a go on your whiteboard using a number line.
