How can something sooooo simple pack such a big punch?
Here is a great warm up to use with your students that hits on multiple common core standards across multiple grade levels. It is a nice way to strengthen and reinforce key skills and concepts that students need in order to be successful.
I use this in my class at least twice a week, in lieu of my daily warm up. I am sometimes very deliberate in the date I choose, depending on what I want the students to practice.
