I used this with my Math RIT group. The high kids were very hands on with it and understood the concepts very well.

My students enjoyed the video introduction, which was a great support for my lower-level readers! The slideshow was great for them to work through and was a good way to check for understanding. Thanks for the quick, low prep slideshow to supplement our work on identifying angles.

Great way to review angles. I copied each slide then posted it around the room and partners when around answering them. Kids love this activity plus the students get to move around
