A free website offering free, high quality math videos, the Khan Academy, has been getting a lot of press lately. Salman Kahn, the creator of the Khan Academy, has created over 2,000 YouTube videos that are helping students of all ages. Check it out!
This video on multiplying expressions has been viewed over 34,000 times on YouTube. The Khan Academy features videos from the simplest math concepts to the most advanced.
MathsMaster.Org has great videos found on iTunes.
Their basic operations videos are well developed and they are working on adding more algebra, geometry and data videos.
Here is a video from Maths Master. You can see how this site "keeps it simple" for math students too. If you are a math teacher or you have students who need additional support, these free video websites should be a part of your instructional and support repertoire.
I hope you find these websites helpful as you work to differentiate instruction, engage your students, and support learning options. Enjoy!
