This is a cooperative learning structure that allows each student to be held accountable for their own individual work, while working together with their classmates.
In this structure, one student solves problem A, another solves problem B. If done correctly, the answers will match. The self checking gives the teacher freedom from the "Is this right?" questions, allowing you to really focus on helping struggling students. This is one of my favorite ways to practice problems in class.
This activity contains 7 problems for each student:
-3 binomial x binonmial
-2 binomial x trinomial
