# Day 20: Around the world with integer addition and square roots

It’s Friday and I wanted to get the kids up and moving around. After we reviewed the homework, both standard and pre-algebra students needed some additional practice on the concepts they’ve been studying so I assigned partners for board work.

Standard students working on integer addition.

The pairs took turns completing three problems on the white boards and I was able to check their understanding. When the three problems were completed, one partner stayed and the other joined a new partner in clockwise fashion. They then alternated completing the next three problems, and so on. Everyone talked math, got a chance to work with different people, and had a partner to help them if they needed it.

Pre-algebra students are getting the idea. It looks as if the problem #s have been included in the problem but they’re not. We still need to work on clarity and how to show work.

At first the students were confused on how the rotation worked, but once we did a round they easily got the hang of it. My pre-algebra class has 29 students so not everyone could work at the whiteboards mounted in the front and rear of the room so I broke out some 2’x2′ white boards and set them along the perimeter and on few desks to accommodate them.

It was a great way for me to see their work and help them as needed.
