Students explore models of three-dimensional shapes. In this geometric shapes lesson, students use hands-on manipulatives to explore three-dimensional shapes. Students predict whether each shape will roll or slide.

Learners build nets of three-dimensional prisms based on the dimensions they are given for hexagonal prism, triangular prism, rectangular prism. Working in groups, they use their prisms and calculate the Surface Area and Lateral Area.

Tenth graders investigate the history of geometry and its different shapes. In this geometry instructional activity, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the...

Young scholars create sculptures of a human head with Sculptamold. They discover the differences between two and three dimensional art. They combine art history, aestetics and personal expression to create a sculpture.

Students compute surface area and volume of prisms. In this surface area lesson plan, students find the surface area and volume of rectangular and triangular prisms. Independently, students use their computers to determine the volume,...

Students define vocabulary related to geometry and calculate the volume. In this geometry lesson, students calculate flow rates, and volume as it relates to a water plant facility. They calculate the volume of three dimensional shapes...

Learners identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

Students use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.

Double the dimensions, quadruple the surface area. Pairs build similar prisms and compare the ratios of their surface areas and volumes to the ratio of the heights. Given two similar cones, partners determine the ratios of the lateral...

What type of corners does this shape have? Young geometers examine 12 shapes, circling the square corners in each if they have any. There are two examples demonstrating this concept, but be sure scholars understand the difference between...

Young scientists learn about plate tectonics and the three different types of faults (normal, reverse, and strike-slip) using foam models. The activity also covers common types of locations where these faults are found.

Four is the perfect number—if you're talking about parallelograms. Scholars determine a possible fourth vertex of a parallelogram in the coordinate plane given the coordinates of three vertices. They read a conversation...
