Today I cleared away all the seats and we worked from the floor. Students were given an expression and a grid with 20 squares to fill in. Kiddos tested their understanding of simplifying expressions and equivalent expressions today. They would pick a paper wad and then simplify it, and then decide if it was equivalent to what they had or not inorder to put it in the correct spot on their sheets. They were engaged the entire hour.
For those that did not finish, I have a day 2 version of this activity for them to complete.
