Take young scholars on a trip through history with this unit on the mathematics and architecture of the Mayan civilization. Starting with a introduction to their base twenty number system and the symbols they used, this eight-lesson unit...

Students find real-world examples of a variety of geometric shapes. They conduct research, record observations, and write descriptions. They create a classroom cityscape and highlight the information they gathered. They present an oral...

Students explore geometry by completing a color puzzle. In this shape identification lesson, students utilize deductive reasoning to complete a Google SketchUp puzzle with trapezoid, triangles and rectangular shapes. Students...

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Students observe geometric shapes in their everyday lives.  In this middle school/high school mathematics lesson, students use their cell phone to record and publish their observations about the geometric shapes they...

Young scholars explore the mathematical properties of traditional American Indian lodges. They examine the effect of increasing sides of a polygon, calculate the surface area of prisms and cylinders, and construct a classroom size...

Learners choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.

Third graders become more familiar with various geometric shapes by completing the games and activities in this lesson. They keep track of the number of each shape they use in each of the three ways.

Studnents examine the degree of biodiversity that exists in one's everyday environment, in order to develop an understanding of how scientists classify organisms and to explain why biodiversity is important for living things.

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Sixth graders examine the causes of the stock market crash of 1929.  In this integrated math/history unit on the stock market, 6th graders study, research, and read stocks, visit a local bank, and create a PowerPoint to show the...
