This morning found me sitting in the back of Elizabeth Brown’s 8th Grade Summer Academy class. Opening activity: Dot talks. I always enjoy Dot Talks because I love hearing student thinking and the variety of ways that people perceive things. Most students were quiet in their participation and Elizabeth worked to draw them into conversation.… Continue reading Moments from our 8th Grade Summer Math Academy (part 2)

I wish I could give credit to exactly who produced the video but at the end it simply states from “The Office of Accountability.” Wow…Not just something hilarious from data folks but from an “Office of Accountability”…That’s amazing! Enjoy!
