- Winter congruent and symmetrical shapes
- Students learn about congruency and symmetry. They complete a symmetrical tree that is complete with congruent ornaments.
- Format: lesson plan (grade 3 Mathematics)
- By Julie Little.
- Tangrams
- While reading Grandfather Tang's Story by Ann Tompert, students will be using tangrams to create the animals that the fox fairies are turning themselves into in this story.
- Format: lesson plan (grade 3 Mathematics)
- By Dawn Coleman.
- 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.
- Format: lesson plan (grade 3 Mathematics)
- By Rendy King.
- 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.
- Format: lesson plan (grade 3 Mathematics)
- By Lisa Fletcher.
- 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.
- Format: lesson plan (grade 3 Mathematics)
- By Julie Little.
- 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. - Format: lesson plan (grade 3 Computer/Technology Skills and Mathematics)
- By Barbara Waters.
- 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.
- Format: lesson plan (grade 3 Mathematics)
- By Robin Ward.
- 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.
- Format: lesson plan (grade 3–5 Mathematics)
- By Cherl Hollada, Libby Morrison, Michelle Kaczynski, and Susan Pope.
- 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.
- Format: lesson plan (grade 3 Mathematics)
- By Mary Allen.
- 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.
- Format: lesson plan (grade 3 Computer/Technology Skills, Information Skills, and Mathematics)
- By Mary Rizzo.
- Exploring geometric shapes
- These hands-on activities make learning about geometric shapes more appealing to students.
- Format: lesson plan (grade 3 Mathematics)
- By Debbie Fox.
- Congruent figures
- This is a fun, hands-on activity to help students identify congruent figures.
- Format: lesson plan (grade 3 Mathematics)
- By Jennifer Robinson.
- 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.
- Format: lesson plan (grade 3 Mathematics)
- By Renee Allen.
