I like to use videos in lessons when they are appropriate. They can be great for explaining a key concept, showing students some extension material, or even setting them a problem. There are lots of places to find great videos online for use in the Maths classroom, and in trying to keep track of these, I have started a spreadsheet with links to them.
Below is a viewable copy of the spreadsheet with the links I have added so far. Feel free to use these videos in your own teaching. But to make this even better, why not add some of your own videos to the list using this link.
Hopefully this can become a really useful list that Maths teachers around the world can make use of! Enjoy.
I am a maths teacher looking to share good ideas for use in the classroom, with a current interest in integrating educational research into my practice.
