Know Your Polygons!
Students identify and categorize different polygons. In this polygons lesson plan, students research and identify properties of polygons, identify different polygon shapes, and categorize different triangles and quadrilaterals.
Curated OER
Sorting and Classifying
Fifth graders are engaged in sorting and classifying geometric shapes of various colors and sizes. They discuss the properties of these shapes and illustrate a range of classifications using Venn diagrams.
Curated OER
Folding to Make Shapes
Second graders identify different polygons and their attributes. In this geometry lesson, 2nd graders get to know polygons by studying the vocabulary and finding polygons in their classroom. They create these shapes and then find their...
