Lesson Plan: Classifying Shapes and Figures - Grade Four - Grade 04
Grade:04
Summary:In this lesson, students sort two-dimensional shapes and identify and describe attributes of the shapes. Attributes for sides (congruent, parallel, perpendicular) and angles (congruent, acute, obtuse, right) are investigated. Then, students compare two-dimensional shapes with three-dimensional figures. They identify attributes of three-dimensional shapes such as cones, cylinders, prisms, pyramids and spheres. Students describe and compare the attributes and build models with physical materials.
