6-8
In this lesson, students classify polygons according to more than one
property at a time. In the context of a game, students move from a
simple description of shapes to an analysis of how properties are
related. This lesson was adapted from an article which appeared in the
October, 1998 edition of
Mathematics Teaching in the Middle School.
3-5
Explore
geometric solids and their properties.
6-8
In this lesson, students explore regular and semi-regular tessellations. Students use manipulatives to discover which regular polygons will tessellate and which will not. Students will use geometry and measurement to investigate the three regular and eight semi-regular tessellations.
6-8, 9-12
In this lesson, students use polydrons to create nets of rectangular prisms. They discover that there are many configurations for rectangular prisms with the same volume, and determine that certain configurations minimize surface area. The lesson continues in a discovery activity related to building the most cost-efficient and appealing fish tank.
3-5
In this lesson, students build a three‑dimensional model from their two‑dimensional blueprint. In addition, they solve problems related to constructing and decorating their clubhouse.
3-5
In this lesson, students discover the uses of geometry and measurement in the world of architecture as they are introduced to the clubhouse project.
3-5
Students identify which geometric solids can be made from given nets. Students also create nets for common geometric solids.
3-5
Students construct physical models of geometric solids.
3-5
Students discover Euler's Formula, a way of calculating the number of faces, edges, and vertices of geometric solids.
3-5
In this interactive geometry investigation, students explore geometric solids and their properties. Specifically, students count the number of faces, edges, and corners (vertices) in various solids.
