Summer SAVY 2015 (Week 1, Day 1) – Shaping up in Geometry (Rising 2nd/3rd)

Posted by on Monday, June 8, 2015 in SAVY blog.

Welcome to Shaping Up in Geometry. These mathematicians came ready to explore all the geometry in our world. Points, lines, segments, rays and angles are the building blocks of geometry. Today we began collaborating as we identified attributes and characteristics of various polygons, and non-examples, too. We explored relationships among quadrilaterals. It’s a joy to see these mathematicians take risks to share their ideas, and develop the confidence and communication skills to defend their conjectures.  In SAVY, we are able to take geometry beyond the identification stage, through designing, drawing, building, modeling, classifying, etc. Today we investigated plane 2D geometry. We are “thinking outside the box” as we visualize extensions of the more obvious geometric figures. We are making geometry connections in art this week as well. Today we began making a Mondrian drawing. We read The Greedy Triangle.

These SAVY mathematicians were intrigued by our Hoberman sphere [basically a collapsible geodesic dome]. They are making observations about the shapes involved [how many triangles, pentagons, stars…] and will try to create one with K-Nex. [Hoberman sphere link: ]
Tomorrow we will investigate solid geometry. We will create 3D prisms and pyramids and make connections with cross-sections. We’ll consider attributes of polyhedra [solids with flat faces] as well as non-polyhedra [spheres, cones and cylinders]. Be on the lookout this evening for geometry in your world.
