20 Question Numbers Sense warm ups to get brains thinking at the start of class. Covering common core standards for 6th graders. Idea adapted from Kristi Cornwell who has a product for younger learners. This resource has 5 days worth of warm up with the answer keys for each day. I used this format for a few weeks with my own classes and then switched to a half page layout that they could see from the back of the class when projected on the wall. Let me know which format you like better and I will post more of that size.
