Today's work is going to be on factors and multiples. We will look at what factors and multiples are and how they can be worked out.
Unsurprisingly, to be able to work on factors and multiples, it is important to know your TIMES TABLES!
The following BBC clips give an introduction to factors and multiples. At the bottom of the clips are little quiz for you to take to see if you understand.
A factor is a number that is in the times tables of a bigger number. For example, if we take the number 10, what times tables is the number 10 in? It is in the 1 times table (all numbers are!), the 2 times table, the 5 times table and the 10 times table, so the factors of 10 are 1, 2, 5 and 10. Watch the following video to see this explained: https://www.youtube.com/watch?v=0NvLtTwnUHs. Please stop the video and re-watch any parts that you don't understand or need clarifying. If more help is needed on this, please contact me.
A multiple is any number in a times table. For example, a multiple of 5 would be anything in the 5 times table, so 10, 15, 20, etc. It doesn't stop at 60 though, so any number that ends in a 5 or a 0, like 675, would be a multiple of 5 as well.
In Resources you will find a variety of challenges. Be confident and try the one you think will push you however if you find it too difficult, do not worry and try the one before. Please try at least 1 of the multiple sheets and 1 of the factor sheets.
