Curated OER
Pythagorean Theorem Investigation
Eighth graders investigate the Pythagorean Theorem and practice applying the theorem to various triangles. Finally, in the next lesson in the sequence, 8th graders create a song or a story to help them remember the Pythagorean Theorem.

Curated OER
Design-a-Lesson-Packaging a Product
Students in a teacher education class address consumer related issues involving packaging. Using volume, surface area and graphs, they create a package for a given volume of a product. They design modifications for this lesson and to...
Curated OER
The Box with the Greatest Volume
Students use measurement tools to measure the nearest 16th of an inch. They connect fractions and their decimal equivalents and compare this with other decimals. Finally, the class uses algebraic concepts and formulas to solve problems.

Science Inquiry Lesson: Mapping Project
Students explore the methods of creating maps. They create a map of Animas River Park using a compass and measuring tape, develop a single map from the team map sections, and devise another map of the Animas River Park using a GPS unit.
Curated OER
Making Shapes
Tenth graders construct geometric figures using compasses and protractors.

Modular Houses
Students, working in pairs, are presented with the problem. They are asked to design modular houses using four cubic modules, all the same size, which touch each other on complete faces. They must draw each of their houses on isometric...
Curated OER
Symmetry
Sixth graders explore symmetry and discuss the difference between a rotation and reflection. Using hands-on activities, such as folding paper shapes, they discover how to find the lines of symmetry and symmetrical characteristics. As a...
