- Investigating surface area
- This is a hands on lesson best used to introduce geometry students to 3-dimensional figures. Students will have the opportunity to draw 3-dimensionally and create collapsible figures which can be used to develop the standard surface area formulas.
- Format: lesson plan (grade 7 Mathematics)
- By Jennifer Bronzini.
- 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.
- Flipping around pentominoes
- The students will use Unifix cubes to create the twelve different pentominoes. The students will join 5 Unifix cubes to make different shapes that will lie flat on a table or level surface. The students will then test for new shapes by flipping, sliding, or turning to create each different pentomino.

- By Dianne Wingate.
- 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.
- Quick Draw
- In Problem centered math, page 4
- An engaging math activity that helps students develop and talk about spatial reasoning.
- By Grayson Wheatley.
- Remembering the Revolution
- An analysis of the painting The Apotheosis of Washington in the U.S. Capitol rotunda, and a discussion of how it reflected the values of Americans on the eve of the Civil War.
- Format: article
- Inside, outside, and all around
- Students will distinguish between perimeter, area, and volume. They will use tangrams and graph paper to create two-dimensional figures that will be measured for area and perimeter. By creating layers of centimeter cubes, the students will explore the concept of volume.
- Format: lesson plan (grade 4–5 Mathematics)
- By Angeli Jarman.
- Dear Tootsie Roll company
- The students will measure the surface area and wrapper area of five pieces of candy. Using appropriate formulas and measuring techniques, they will complete information needed for a spreadsheet and database. Students wrap up the lesson by writing a letter to the company with the most wasted paper to explain how the waste affects them as consumers and a suggestion for correcting the problem.

- By Tonya Thompson.
- Creating a community
- Students will design a community and take into consideration the structures and human resources necessary for a balanced community. They will evaluate their community as they evaluate differences between wants and needs.
- Format: lesson plan (grade 2 Social Studies)
- By Helen Byrd.
- Differences across the curriculum: Part 2
- This set of lessons can be used with "Differences across the curriculum: Part 1" as an integrated approach to exploring diversity with eighth graders. The unit will revolve around the use of the drama version of "The Diary of Anne Frank." Students will learn how diversity creates bias, which leads to conflict, where students confront their bias and practice tolerance. These parts reflect the four core curricula in an interwoven approach to teaching students to confront their biases, learn tolerance, and infer the impact of these on today's society. This activity, Part 2, is meant to augment the pre-reading activities completed in Part 1 in a Social Studies class.
