Freebie: Geometry Math resource for elementary teachers to show the relationship between triangles and rectangles

Triangles Composer

I thought it would be a good idea on this busy “Hour of Code” week to treat students and teachers to this free resource made with Adobe Flash all the way back in 2010. While teachers and parents can use the tool to show the relationships between basic geometric shapes, students can let their imaginations run wild and think about all they can build using only triangles and rectangles.
