Attached are 10 task cards over order of operations. I have 3 copies of the same 10 task cards. They are color coded to keep organized at station work. I usually print them on card stock and laminate them so that I can reuse at centers. Each problem includes a QR code with video tutorial on solving each equation. Once they are laminated, the students can write on them with dry erase markers and then use the code to check their work.
