Sketching Pyramids
Students sketch and identify properties of pyramids. In this geometry lesson, students create nets to identify three dimensional shapes. They sketch cones, prisms and pyramids.
Curated OER
A Christmas Project
Seventh graders publish a letter and spreadsheet using the computer. They build a three-dimesnsional object with construction paper and develop a Christmas object using coordinates on a graph. Students compose a response in their journals.
Curated OER
Sketching Spheres
Students investigate spheres through sketches. In this geometry lesson, students sketch two and three dimensional shapes creating nets. They find and differentiate between the nets for prisms, pyramids, cones, cylinders and spheres.
Curated OER
Exploring Properties of Rectangular Prisms
Students explore the properties of rectangular prisms. For this geometry lesson, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.
Curated OER
Surface Area of Cones
High schoolers find the surface area of cones. In this geometry lesson plan, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the...

Exploring Volume of Cylinders
Tenth graders investigate the volume of a cylinder. In this geometry instructional activity, 10th graders create three-dimensional cylinders and use a ruler to determine the dimensions. The instructional activity progresses...
Curated OER
Mass
Students determine how mass is a property of an object that can be measured, and examine how size affects mass. They work with balances and determine what units of measurement are associated with mass. Finally, they determine the...

Linear Perspective: Painting Distance with Size
Young scholars examine a simple set up to measure the change in the apparent size of an object as it moves away from them.
Curated OER
Circle Art
Students investigate two and three dimensional shapes. In this geometry lesson, students write equations of circles and graph them correctly. They create pictures using circles.
Curated OER
Squares
Students identify shapes that are squares. In this square lesson, students identify the square items and then sing songs about squares.
Curated OER
3D Computer Imaging Class: Cross-Section Lesson
Students use 3-dimensional materials to create a simple 3-D object. They think about different ways the object could be sliced. Students choose one way to slice the object, and draw the sliced shape on paper or computer. Using a 3-D...
