Foldable reviews horizontal, vertical and oblique (diagonal) cross sections for the following 3-D figures:
Foldable is editable and can be modified to swap out different 3-D figures.
This is a great overview of cross sections. I have students draw the 2-D shape that results from each cross section and write the name of the 2-D shape. On the second day, I do a lab with play-doh and floss to demonstrate this skill. I then apply perimeter and area formulas.
