We just finished this activity with 3 of my classes, roughly 65 students. As much as I enjoy this activity, I do not enjoy the little scraps of paper all over the floor, the students who still cut paper as skillfully as a Kindergartener, and the s l o w n e s s of the students' pace with just creating the posters. Not to mention the grading. I don't mind the grading, it's just that I'm not willing to drag them all home to grade, I try to get them done at school. Oh and I almost forgot to complain about buying the supplies.
Then I received an email from our tech coach about making virtual posters with Google Drawing. If only she had sent this one week sooner. Better yet: why didn't I think of this?
4(x + 2) + 3x + 5 = 34
4x + 8 + 3x + 5 = 34
7x + 13 = 34
7x = 21
x = 3
