Here is a great set of Year 3 Maths teaching resources. These could be used to help revise for the KS1 or KS2 SATs tests, as a resource for a supply teacher or simply as something to do at home.
Years ago I wrote a wide range of different Year 3 Maths PowerPoint lessons which followed the Governmental guidelines of the time.

Originally, I was asked to send them to some friends, and so I thought I would share them with all the world via TES. Since then they have been viewed over 40,000 times! This is my most downloaded set of presentations I have ever made on TES.
