Connect multiplication with geometry, with a new twist - polygons!
The picture of each polygon allows students to put a slash through each side as they count them. Hopefully, in conjunction with your other multiplication activities, they will begin to see the pattern, and at the same time reinforce their knowledge of polygons!
Your GATE students can label the polygons with acute angles or obtuse angles and find the equilateral polygons.
This is great as a center, independent work in a math workshop or homework.
