Maths videos
Here is a link to the DoingMaths channel on YouTube. This contains videos I have made using PowerPoint. I find videos to be a great change from the normal lesson and very useful to stick on a projector/electronic whiteboard while you stand at the back of the classroom and keep an eye on everybody.
Remember to subscribe to the DoingMaths channel to keep up to date with all the new releases.
