I created this graphic for a group of students who did not perform as hoped on this standard. I used it to remediate. My students actually thanked me for creating this and said it really helped them. Things they liked: it forced them to be organized; if the final answer was wrong, it allowed them (and me) to identify exactly where the mistake occurred. If used for a graded assignment, it would allow for partial credit. I can see it as a great tool also for students with disabilities.
