Here's an easy activity for breaking down the steps of the order of operations. Each of the two pages has 5 problems to solve using the order of operations. Above each operation is a bubble. The students should write numbers in each balloon to indicate how to solve the problem. It's the teacher's discretion whether to then have the students solve the problems using their outline.
My co-teacher and I have found this really useful for some students because it makes them worry more about the steps rather than solving the problem. If you can get them to slow down and reflect on the process, then getting the right answer becomes less important.
We copied the activity onto cardstock (for durability), front and back, and slipped the papers into page protectors so the students could use dry-erase markers.
