Let’s look at the 3 times table.
2 times 6 is 12
Here is 6 again
So to find 3 times 6
we double 6 and add another 6.
3 times 6 is 18
![Page 77: Year 6 SATs Booster Maths 2 Multiplication and Division Part 1](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e4c5503460f94b41b88/html5/thumbnails/77.jpg)
2 times 7 is 14
Here is 7
To get three times we must add another 7 to give 21
To find 3 times 7
we double 7 and add a 7.
So 3 times 7 is 21

5 times
We know 10 times 6 is 60
5 times 6 is half as much.It is 30.

To multiply by 5 we multiply by 10 and then halve.
5 x 6
10 x 6 = 60
Then we halve 60 to get 30.

6 times
To multiply by 6 we multiply by 3 and then double.
Here is 3 x 6 = 18
Double and we get 6 x 6 = 36
![Page 86: Year 6 SATs Booster Maths 2 Multiplication and Division Part 1](https://reader030.vdocument.in/reader030/viewer/2022032707/56649e4c5503460f94b41b88/html5/thumbnails/86.jpg)
Remember
6 x 1 = 6 that’s easy6 x 2 = 2 x 6 so we double 66 x 3 = 3 x 6 we can do that6 x 4 = 4 x 6 we can do that6 x 5 = 5 x 6 we can do thatSo we only really need to use 3 times and double
for6 x 6, 6 x 7, 6 x 8, and 6 x 9
