## Reflection: Checks for Understanding Multiply and Divide Monomials-Jigsaw day 1 of 2 - Section 1: Warm Up

This was a really straight-forward warm up to get things going today.  That said, sometimes a warm up like this is really important.  I used this warm up today to help me assess where students were in their basic skills with combining like terms.  Because the next two class periods were going to be driven mainly by student-centered work I wanted to be confident that students were up to the task.  I was pleasantly surprised to see how well students worked with the algebra in this warm up.  Their understanding of how to combine like terms in a variety of situations gave me the signal that we were good to move ahead with the day's lesson.  Had I seen some students really struggling with this activity, I would have pulled them into a small group and more closely facilitated their presentations during the jigsaw activity.
