In math workshop, our new unit of study is on geometry. Yesterday's lesson explored polygons. We began by exploring what a polygon actually is. By studying examples and non-examples, we found out that polygons have straight sides, at least three vertices, one interior, and is a closed shape. We then set out to build as many different polygons as we could. After each team was given straws and twist-ties, they quickly began building. After 10 minutes of creating shapes, we decided to classify our polygons by their number of sides. We built everything from triangles to decagons! Here are a few pictures of our students building their shapes.
