How Do You Measure Up?
Students measure their body. For this measurement lesson, students use a string to measure their height and the circumference of their head. They record this information on the worksheet provided and answer questions as a group.
Curated OER
A Rectangular Prism and Its Net
Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

Principles of Flight: Flying Paper Airplanes
Students investigate ways to enhance an object's flying ability. In this model construction lesson plan, students construct two paper airplanes, one of which is twice as big as the first. Students compare and contrast the two...
Curated OER
Area of Polygons
Students engage in a lesson that is about the concept of polygons and focuses upon finding the area. They use formulas provided in the lesson in order to solve problems given by the teacher for independent practice. Geometric figures are...
