Card Sort: Cross Sections

This Instructional Activity is a part of the Lesson 11, Unit 7, Grade 7. In this activity, students practice visualizing cross sections in a more abstract way by looking at images of a solid object that has been cut by a plane and matching those images to the shapes created by the cuts. The cuts made in this activity vary from the previous activity in that the cuts are not all parallel to the base of the three-dimensional object.
