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 are my May selections. Just click on the resource description to download it.

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
