3. Multiplication and division

Lesson

Being able to recall our multiplication facts will help us in this lesson. Let's try a practice problem now.

What is 4 \times 8?

Worked Solution

Idea summary

There are different ways to solve multiplication, including repeated addition and using arrays. We can also multiply our numbers in a different order, so 3\times4 has the same answer as 4\times3.

This video will show us how to find all the factors for a number.

If we multiply 4 by 14, we get 56, so 4 and 14 make a factor pair of 56.

Which of the following options is also a factor pair of 56?

A

14 and 2

B

4 and 7

C

8 and 7

D

2 and 2

Worked Solution

Idea summary

All numbers have at least one factor pair, 1 and itself.

To check if a pair of numbers is a factor pair of a given number, multiply the pair of numbers together.
