Geometry (9th/10th grade) Unit Test clone code.
Awesome. For 5, 6, and 7, I recommend putting the original 3-D shape in the background for the students and have them highlight where the cross section is located on the shape. They can also draw the cross section shape next to the 3-D figure. That way you can assess if it’s a vocabulary issue (horizontal vs vertical, etc) or a visual issue.
