Goal 3

Geometry - The learner will recognize and use basic geometric properties of two- and three-dimensional figures.

Objective 3.01

Use appropriate vocabulary to compare, describe, and classify two- and three-dimensional figures.

Resources aligned to this objective

Talking geometry through quilts
This lesson plan is designed to use quilts as a visual prompt to review mathematics vocabulary associated with geometry in the third grade curriculum. A hands-on activity serves as a practice and review at the conclusion of this lesson.

Solid graphing
The students will review solid figures using a baggie of assorted snack mix (cones, cubes, cylinders, and spheres) and will begin a vertical bar graph showing the number of each solid figure in a bag of assorted snack mix.

Polyhedra: Faces, edges, and verticies (3-D marshmallow models)
Students will review the names of 3 dimensional shapes, create the shapes using marshmallows and toothpicks, and find relationships among the faces, verticies, and edges of different 3-D polyhedra.

Paint tools & geometric figures
This lesson is meant to teach or review for third grade students the use of Paint tools. These tools are generic to many multimedia tools such as HyperStudio and Kid Pix. For the student who is unfamiliar with "Paint," it provides another tool of expression and illustration.
This lesson is also designed to reinforce geometry math skills. This ability to illustrate a three dimensional object on a flat one dimensional surface is important to enable the student to visualize geometry math problems.

Our geometric world
The students will use newspaper and magazine pictures to recognize geometric figures within the real world. They will make a collage of pictures showing various geometric shapes. They will write a summary of the shapes that are represented in their collage.

Origami geometry
Students apply their knowledge of geometric terms to follow directions while folding an origami sculpture. Students then solve math problems which relate to the project with follow-up discussions about the project relating to geometric terms such as symmetry, faces, edges, square, triangle, plane, etc.

Monster symmetry
Students will make a "monster" through symmetry using white paper, pencils, and scissors. This activity will help students visualize how to identify objects that can be divided symmetrically.

A geometric field trip
Students conduct a field trip around the school (inside and out) looking for examples of geometric shapes. They record their findings using a digital camera and present their findings in a multimedia presentation.

The Greedy Triangle
Students review geometric terms by making predictions about what the Greedy Triangle will become as the teacher reads the book, The Greedy Triangle. Students will create geometric creatures after the review.
