Learners use cubes to construct and visualize two-and three-dimensional shapes to develop spatial thinking and review basic geometric principles through real-life applications. They are given the opportunity to build and build and take...

In this science and engineering worksheet, students use dimensional analysis to solve each of the problems stated on the sheet. They illustrate their work and how they arrived at their answers by using significant figures for their final...

First graders create two-dimensional shapes. For this shapes lesson, 1st graders learn about different two-dimensional shapes. Students have many hands-on experiences with these shapes including the use of geoboards, shaving cream, yarn,...

Students identify and correctly name three-dimensional solids; cones, spheres, and cubes. In this three-dimensional figures lesson, students  build a cube by matching colored square faces to a correct word. Students then...

Students identify the volume of cones and pyramids. In this geometry lesson, students derive the formula for cones and pyramids. They calculate the volume of cones and other three dimensional shapes.

Sixth graders create three-dimensional black and red figured Greek Vessels out of papier-mache, while researching and discussing Greek history, and myths of powerful gods and goddesses.

Learners 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, and volume...

In this nets of figures instructional activity, students determine which given shapes will make a shown net, then name the shapes uses. A reference web site is given for additional activities.
