With the change of Geometry to the CPM curriculum – I have links to helpful videos below:

These videos include the Math Notes from the text to help students review content and gain understanding and mastery!

(Some videos have been reused from my previous curriculum (I will say a different section number in the video), but it will still provide the same information about the material!)
