Developing Intuition About Shapes Using Dynamic Tools

75 Minutes

By the end of grade 5, students should be able to "classify two-dimensional figures into categories based on their properties." However, students are expected to do this based on experiences with pattern blocks and static pictures and have few, if any, opportunities to truly explore the shapes they're expected to classify. We'll use a dynamic tool to notice and wonder about, compare, and match up different triangles, then discuss how such activities can help students develop their "shape intuition."
