## Lesson Plans

In this lesson, students categorize shapes identifying the attributes of quadrilaterals.

Type: Lesson Plan

This lesson helps students to realize that shapes have identifying attributes that define them. Students should also discover that a shape can have multiple names based on the definitions of that shape.

Type: Lesson Plan

Snowflake Geometry: No Two Alike!:

In this lesson students will make snowflakes, promoting creativity and self-expression, and use them to identify geometric terms. It also gives them an opportunity to follow a sequenced set of instructions for a given outcome.

Type: Lesson Plan

Angles All Around Us:

This is a lesson that introduces right, acute, obtuse, reflex, straight angles in a fun and challenging way.

Type: Lesson Plan

Points, Lines, and Angles, Oh My!:

In this lesson, students work to identify points, lines, line segments, rays, angles and perpendicular and parallel lines. Students create webs of yarn and analyze the web for geometric properties listed above. A teacher can select which vocabulary terms are appropriate for the class.

Type: Lesson Plan

Building Blocks of Geometry:

Students will be introduced to point, line, and plane, the building blocks of geometry, and use them to develop an understanding of new terms, including line segment,  intersecting lines, parallel lines and perpendicular lines. Students will participate in a Building Block Scavenger Hunt, using paper and pencil to draw examples of specified terms that they find outside of the math classroom. The students will compose a poster to display their images of the required terms.

Type: Lesson Plan

Geometry, USA:

Students will draw a town based on a set of given directions using the geometry terms (parallel, perpendicular, and intersecting lines). This activity is designed to be taught after the students having learned the meanings of the geometry terms and the ability to identify examples of each.
