Worksheet for Pi
Who needs a pie-eating contest when you have a pi-ology game! Celebrate March 14th with a fun board game about pi and other geometric concepts. As learners answer questions about geometry, they move around the board to collect tokens.
Mascil Project
Teaching Geometry Through Play
Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...
Curated OER
Geometry in A Box
Students identify 3-dimensional geometric shapes and list the characteristics of each. Using modeling clay, they create their own models of specified geometric shapes. Students create and design a box to store their geometric models.
