Crazy 8s: Glow-in-the-dark Geometry & Pattern

We began a new "Crazy 8s" Math Club this week with twelve 3rd, 4th and 5th graders from the Project Promise After School Program at New Hampton Community School. This eight week program will reinforce math skills in a fun and experiential way!

This week we built geometric shapes out of glowsticks. First, we made different kinds of triangles, like equilateral and isosceles, then we made four-sided shapes like trapezoids, parallelograms, rhombuses, rectangles, and squares. 
Then, working together, we made repeating patterns on the floor. Certain regular polygons worked perfectly, like triangles, squares, and hexagons. We had to work closely with each other to be sure our shapes were accurately made so the pattern could continue. We also figured the area and perimeter of some of our biggest shapes!
How many triangles do you see in the shape below? 
Count carefully!
