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 shapes and creating composite shapes (1.G.A.1 & 1.G.A.2). 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 by using 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 distinguish between defining (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size). In addition they will create a t-chart and sort/draw objects by attribute.
- Segment 3: students will distinguish between defining and non-defining attributes (e.g., color, orientation, overall size) of two-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
