Geometry - Shape Classification (2D) - Intro

This math unit begins by introducing basic concepts of 2D shapes, focusing first on identifying simple geometric figures by matching shape names and images. As the unit progresses, students delve deeper into geometry by counting vertices and sides, which supports their ability to classify shapes more specifically. The lesson complexity increases as students learn to differentiate shapes based on congruence and similarity, involving analysis of angles and side lengths. Additionally, the unit covers symmetry, challenging students to identify symmetric shapes and count lines of symmetry. Toward the end of the unit, students work on naming shapes based on the number of sides and recognizing polygons, including a detailed examination of specific polygon families like parallelograms. This progression from basic identification to more detailed classification prepares students to understand and analyze a range of geometric properties and relationships.
