Fill and Wrap It Up
Middle schoolers find the surface area and volume of the solid figures by measuring the length and the height of each face and base. They use concrete models to derive formulas for finding perimeter, circumference, area, surface area,...

Principles of Flight: Flying Paper Airplanes
Students investigate ways to enhance an object's flying ability. In this model construction lesson, students construct two paper airplanes, one of which is twice as big as the first. Students compare and contrast the two...

Learning by Logic - Total Surface Area
Geometers calculate the area of plane surfaces using the formulas for the area of a square, rectangle, and triangle. They develop the formula for calculating the total surface area of two geometric solids: the cube and rectangular prism.

Fishing for the Future
Learners research Hawaii's fishing regulations. In this conservation lesson, students explore the reasons behind ocean conservation. Resources are provided.
Curated OER
Smile Metric Style
Students take measurements using a metric ruler, find a sum of multiple metric measurements, and use a histogram to graph their results.
Curated OER
Leaping!
Students properly leap and measure their distance. In this leaping lesson, students practice leaping for accuracy and proper form. Students estimate their leaps and measure with rulers. Students determine distance covered by the entire...
