Product Description
By the time kids get to high school they either already have the order of operations mastered or no amount of remediation can help.

This two day lesson takes a different approach by setting up clever problems for the students where they change what's written by adding parentheses to group things, changing the order of calculation to arrive at a pre-determined answer.

What happens is misconceptions are exposed, which then, in turn, allows students to replace their misunderstandings with correct understanding.

The first day's lesson gives students things like 3 x 2 + 5 = 21 and they have to place the parentheses appropriately to make it equal 21. It is a powerful learning experience for the students, but you must facilitate a lot of group work and discussion.

The second day's lesson is closely modeled by this video: https://youtu.be/-P884DAepn0 It really should address how all of the operations can be related back to addition, which is basically just counting. It's a powerful realization for students to experience.

There is homework for both days that really will make the students think about numbers.
