Building Shapes and Figures

Miss White has been teaching the students all about the 2D shapes (circles, squares, triangles) and 3D figures (cones, spheres, cubes) that surround the children each day.  This week, she gave the students the opportunity to try and build their own shapes and solids.  The building materials were a big hit: marshmallows and toothpicks!


While not all of the designs or attempts worked out, the students demonstrated their knowledge and had an amazing time exploring, testing and experimenting.

 

Some Ontario Curriculum Expectations fulfilled by this activity include:

Geometry and Spatial Sense

*  build three-dimensional structures using concrete materials, and describe the two-dimensional shapes the

 structures contain

*  identify and describe common two-dimensional shapes (e.g. circles, triangles)

*  identify and describe common three-dimensional figures (e.g. cubes, cones)
