This set of warmups is great for review of the 8th grade Common Core standards each day.** I have these waiting on the students' desks when they come in, and after a set amount of time we go over the answers together, usually with several students taking turns doing the warmup under the doc cam. Depending on the pacing of the day, I may have students complete only two of the problems, or even just one if it is a complex problem.
This set has 10 warmups with accompanying answer keys.
I really strive for mastery of a topic, so my warmups cycle back through previous concepts in the unit to keep my students constantly reviewing. As we move through the units, I will often go back to warmups from earlier units to ensure students are maintaining those earlier concepts as well.
** This particular set is a review of number sense standards for 7th grade. I use these with my 8th graders at the beginning of the year as a review.
