#### Worksheet Overview

This activity is about multiplying by 11.

Multiplying by 11 is easy for most facts.

Let's look at the eleven times table below:

1 × 11 = 11

2 × 11 = 22

3 × 11 = 33

4 × 11 = 44

5 × 11 = 55

6 × 11 = 66

7 × 11 = 77

8 × 11 = 88

9 × 11 = 99

10 × 11 = 110

11 × 11 = 121

12 × 11 = 132

For all the facts up to 9 × 9, we simply double the digit of the number we are multiplying by 11.

For 10 × 11, we can use place value to multiply by 10 moving each digit one place to the right.

For 11 × 11 and 12 × 11, you need to memorise the facts!

Let's try an example question together!

Example

A cookie has 11 chocolate chips.

How many chocolate chips do 9 cookies have?

What is 9 times 11?

Using our pattern, we know that nine lots of eleven is ninety-nine.

9 × 11 = 99

What is 11 times 9?

11 × 9 = 99

9 × 11 = 99

That's it!

So long as we know our eleven times table, this activity will be easy!
