I use this self-checking puzzle activity as a station/center activity before Thanksgiving. Students practice solving one-step addition and subtraction equations with integers. This resource is low-prep - simply print puzzle piece page, cut out the 9 pieces, and copy recording sheets, and you are good to go!

This activity is made for 7th grade students, but would also work well as a review activity or intervention tool for 8th grade students.
