Volume, Surface Area for Cylinders
Seventh graders explore the concept of volume and surface area of cylinders. In this volume and surface area of cylinders lesson, 7th graders break cylinders into their base shapes of a circle and a rectangle. Students discover that...
Curated OER
Finding Area
Seventh graders explore the concept of area. For this area lesson, 7th graders determine what measurements are necessary to find the area of a rectangle and circle. Students use area formulas to calculate area or rectangles and circles.

Geometric Shapes at the OK Corral
Students explore geometric shapes. In this math lesson plan, students identify geometric and non-geometric shapes using the computer. Students research geometric shapes in art and architecture.
Curated OER
Geometric Shapes at the OK Corral
Students explore regular geometric shapes. In this shapes lesson, students investigate geometric shapes in the world around them. Students differentiate between regular and irregular shapes.
Curated OER
Angle Action
Students measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This lesson...
