Monday 28th September
On Monday, Tuesday and Wednesday, we will be learning a new method of division called long division. Watch the video above and look at the Long Division slides to learn how to do it and then have a go at the worksheets.
Before you do any work on factors, you need to check you know what factors are, and how to find factors of a number. Do the factors recap before moving onto finding common factors.
At school, we will set factors out like this:
eg: factors of 12 =
1 x 12
2 x 6
3 x 4 There is also 4 x 3, for example, but each number is only listed ONCE.
So, here, 12 has 6 factors, and they come in 3 factor pairs.
Some numbers have an odd number of factors, because they are square numbers.
Eg: factors of 16 =
1 x 16
2 x 8
4 (It is 4 x 4, but 4 is only listed once, so 16 has 5 factors.)
