Each day I select one of my favourite free maths resources that have been uploaded and shared by the generous and incredibly talented users of the **TES Maths website** and tweet it out via **@TESmaths**. I call this feature Resource of the Day (ROTD).

Here is a summary of the previous fortnight.

And of course, all the resources selected are completely free. You just need to register on the TES website to download them. And as ever, a huge thank you to all the teachers who share resources. You make TES what it is
