Grouping Shapes by Parallel and Perpendicular Sides

Objective

Students will spot the number of parallel and perpendicular lines in shapes and then form groups of shapes.

Steps

1. First, students will identify the number of sets of parallel and perpendicular sides in various shapes.
2. Next, they create three or four groups based on their findings in step one.
3. Finally, students venture to the third dimension and look for parallel and perpendicular lines in a cube. For the final question: there are 18 sets of parallel lines in a cube and 24 sets of perpendicular lines. Although technically, we'd call them "edges" instead of lines.
