You can also use this to review on concept with different task cards or worksheets. I just happened to be reviewing an entire standard when we did the activity.
Here is how it worked... Students had both a colored pen and a pencil. They went to each sheet and completed a problem in pencil, careful to show their work. They wrote their initials next to their work. Another student then came and checked their work using a colored pen. If they agreed with their work and their answer, they put a big check mark and their initials. If they disagreed, they showed their work and their answer in the same box, then added their initials.
|Here is a page that has been mostly completed and is waiting to be checked by other students.|
|I put the sheets out in the hallway so that we had a lot of room to work. Two kids could work on one page at the same time.|
|Here is an example of a completed sheet.|
