Geometry: Attributes of Two-Dimensional Shapes & Three-Dimensional Shapes2nd Grade • Half Day Lesson Plan
Subject: Geometry, Math
Type: Half Day Lesson Plan
Skills: Geometry, Two-dimensional Shapes, Three-dimensional Shapes, Defining Attributes, Non-defining Attributes, Composite Shapes
File Type: PDF Document
Materials Needed: Required: copy of Mouse Shapes by Ellen Stol Walsh (picture book), white construction paper, blank paper (2 per student), pencils, crayons, document camera/whiteboard/ chart paper
Printable Resources: Required: printable "3D Shapes" handout (1 per student), Optional: printable "2D Shapes" handout (1 per student), Optional: printable "Exit Slips" as an assessment component (1 copy per student)
Lesson Plan Description
This half day of lesson plans is broken down into 3 separate segments (30-60 minutes each) addressing Geometry: attributes of two-dimensional and three-dimensional shapes. Students will learn key geometry vocabulary, complete interactive math notes, participate in both guided and independent practice, enjoy a read aloud, and create a picture created from only shapes (composite shapes).
- Segment 1: students will identify attributes of two-dimensional shapes (e.g., triangles are closed and three-sided).
- Segment 2: students will identify defining attributes of three-dimensional solid shapes (e.g.; cubes are three-dimensional solids, with six faces, twelve edges, and eight vertices).
- Segment 3: students will distinguish between defining and non-defining attributes (e.g.; color, orientation, overall size) of both two-dimensional and three-dimensional shapes. They will also build and draw shapes with defining attributes to create composite shapes.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
