This week we have been practising multiplication.

To use the grid method with a multiplication you have to firstly partition the numbers.

To do this you have to understand **place value**. So, 116 becomes 100 and 10 and 6. This is done with both numbers. These separate numbers are placed along the top and sides of a grid and then each calculation is worked out individually.

The products (results) of each calculation are then added together to reach the final answer. It’s a simple and elegant way of solving multiplication problems.

A member of 5MC demonstrated how to work through this method.

In this picture we can see that £5.75 has been converted into pence first.

Congratulations on your great blog.

Looks like you will be able to teach me a new trick as I’m only familiar with the old school method of multiplication.

Its great to be up on the blog and hearing what you are all doing. My only concern is how much work will I actually get done during the day in-between checking the various school blogs!
