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 = x 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.
X-Factor Gift Shop Members of the audience have been spending lots of money in the X-Factor gift shop. Use repeated addition to solve these multiplication problems.
X-Factor Gift Shop 8 people buy 4 t-shirts each. How many t-shirts do they buy altogether? What multiplication sum are you going to do? What repeated addition sum will you do?
X-Factor Gift Shop 9 people buy 6 mugs each. How many mugs do they buy altogether? What multiplication sum are you going to do? What repeated addition sum will you do?
X-Factor Gift Shop 7 people buy 4 CDs each. How many CDs do they buy altogether? What multiplication sum are you going to do? What repeated addition sum will you do?
X-Factor Gift Shop 9 people buy 8 pens each. How many pens do they buy altogether? What multiplication sum are you going to do? What repeated addition sum will you do?
Ex4x6= x8= x6= Multiplying by repeated addition
Now it is your turn!
Multiplication is the process of adding equal sets together = 6 We added 2 three times.
