In this resource, students are expected to list the attributes of each quadrilateral. Based on the attributes, they check off if that quadrilateral is a subgroup of a different quadrilateral. For example, they would check that a square also belongs to the rectangle group because it has those attributes.
I've used this as a warm-up, review, homework, quick assessments, exit slips (cut into individual pieces), and a small group activity. Once students have completed it correctly, it also doubles as a personal anchor chart!
