Measurements
Seventh graders solve word problems involving real world situation. For this geometry lesson, 7th graders solve problems related to volume. They apply the formulas taught in geometry.
Curated OER
Cones, Cylinders, Spheres
Students classify polygons by name and shape. In this geometry instructional activity, students identify the lateral surface of each conic. They differentiate between cones, cylinders and spheres.
Curated OER
Box Folding: Predict, Analyze and Measure
Young scholars predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive lesson.
Curated OER
Pyramids- Slant Height and Altitude
Students calculate the height and altitude of a pyramid. In this geometry instructional activity, students define the parts that make up a pyramid. They use the Pythagorean Theorem to find the missing parts of a pyramid.

The Circle's Measure
Students explore circumference and diameter. For this math lesson, students apply their knowledge of circumference and diameter to solve mathematical riddles. Students apply this knowledge to find circumference and diameter of various...
Curated OER
Similar Triangles
Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.
Curated OER
Getting Familiar with Fractals
Young scholars use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.
Curated OER
Angles Lesson Plan
Young scholars stud angles, and then play the "What's Your Angle?" game. They complete at least 10 computer generated problems from the Angles Applet.
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.
