3Sort Shapes Two Different Ways

Show Two Different Ways — Here are five shapes: triangle, square, pentagon, rectangle, hexagon.

Way 1 — Sort them into "3 or 4 sides" and "5 or more sides":

3 or 4 sides:

5 or more sides:

Way 2 — Think of your OWN sorting rule and sort them again:

My rule:

Group 1: Group 2:

4Word Problems

Read carefully. Think about what is happening. Draw if it helps!

A stop sign has 8 sides. A yield sign is a triangle. How many MORE sides does a stop sign have than a yield sign?

My thinking:

more sides

Nora traced 2 pentagons and 1 hexagon. How many vertices did she trace in all?

My thinking:

vertices
