__Wednesday__

Yesterday we worked on factors and multiples. Today we are going to move on from factors to factor pairs. As you know, a pair is 2 so a factor pair shows the 2 numbers that multiply together to make the bigger number.

For example, if we use the example from yesterday of the number 10, we know that the factors are 1, 2, 5 and 10. Because 2 x 5 = 10, this is a factor pair, so 2 and 5 is a factor pair of 10.

This video will recap what we did yesterday and also explain the arc, which is similar to one of the methods we will see below: https://www.youtube.com/watch?v=yJ-T8z2-Zg4.

These can be displayed and worked out in several ways however using a factor rainbow or a factor bug are 2 of the most fun ways to use. Watch the following 2 videos, to see which one you prefer.

Once you have looked at the methods, choose one of them (or even use both!) to try to find the factor pairs of the following numbers:

**Challenge 1: 8, 15, 22, 30 and 32**

**Challenge 2: 9, 14, 24, 36 and 42**

**Challenge 3: 19, 27, 40, 48 and 60**
