# Multiplying methods

This week we have looked at different ways to multiply a 1-digit number by a 2-digit number. Let’s look at 2 of the methods we used.

### The grid method:

The grid method is a written method used to teach children multiplication. It involves partitioning numbers into tens and units before they are multiplied.

37 x 5 : Work this out  by partitioning numbers and putting them in a grid, then multiplying each one in turn: The answers of each multiplication calculation (150 and 35) then need to be added, to find the answer, which is 185.

### The  expanded method of multiplication.

T       O

1         4

x          5

__________

2        0          (5×4)

5         0        (5×10)

__________

7        0

Your turn.  Can you find the product of these operations using your chosen method?

12 x 8 =                          25 x 5 =                              36 x 3 =               44 x 4 =               63 x 2 =
