Multiplication

This week we have really focused on multiplication.

Children should already be able to count in 2s, 5s and 10s
0, 2, 4, 6, 8, 10....
0, 5, 10, 15, 20, 25....
0, 10, 20, 30, 40, 50, 60...

We started by looking at multiplication as repeated addition (this means turning a times sum into an add sum so that it's easier to understand) For example:

5 x 5 =
5 + 5 + 5 + 5 + 5 = 25

Once children understand that multiplication means how many groups there are of a number...

4 x 5 =

Group 1                         Group 2                          Group 3                        Group 4

*****                              *****                            *****                            *****

There are 4 groups and 5 stars in each group. You could count them altogether but it's much easier to learn how to count in 5s and know that 4 x 5 = 20


CHALLENGE: Children who are confident with a range of different multiplication sums and know the timetables off by heart and now looking into the relationship between  ÷ and x


WELL DONE everyone, you had a fantastic lesson learning about multiplication today. Please come back on Sunday and tell me what you've practised or learnt over the weekend...
