Students participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

Tenth graders define the formula for cylinders and use it to solve real world problems. In this geometry instructional activity, pupils differentiate between area, perimeters, 2D shapes, 3D shapes, and volume of prisms, cylinders and...

Learners investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Students investigate the creation of three dimensional drawings. In this geometry lesson, students analyze and complete orthographic drawings. They Cabri software to manipulate and move the drawings around.

Students investigate orthographic drawings. In this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.

High schoolers define and identify shapes by name. In this geometry lesson, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.

Students create a bridge using engineering and geometric concepts. In this geometry lesson, students identify the missing measures of polygons sides and angles. They work together to solve real life situation using problem solving...

Students estimate and measure exact. For this geometry lesson, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their shapes.

Students calculate the surface area and volume of a sphere. In this geometry instructional activity, students define nets, surface areas and volume of prisms, pyramids, cylinders and cones. They use the computer to create nets and...

Students predict the shape of a geometric figure in 3D. For 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.

Tenth graders predict the shape of a geometric figure in 3D. In this geometry instructional activity, 10th graders construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online...
