Third graders explore the attributes of 3-dimensional shapes. For this shapes lesson, 3rd graders examine faces, edges, and vertices of 3-dimensional shapes as they construct shapes using marshmallows and toothpicks.

So many shapes in our vast oceans. Young explorers can discover new shapes in a variety of ways in this lesson. One way is having free exploration with a pattern shape kit handed out by the teacher. Another is by viewing a...

Students explore geometry by participating in a shape identification activity. In this figure dimensions lesson, students identify the difference between 2 and 3 dimensional shapes by their vertices and faces. Students examine blocks in...

Students explore two-dimensional and solid shapes. In this shapes and patterns geometry lesson, students work with a partner to create identifiable objects using tangrams. Students describe the attributes of their shape and their partner...

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

Students define trapezoids and their shapes. In this geometry lesson, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

This is a nice hands-on activity where young geometers create trapezoids and calculate their area by looking at areas of quadrilaterals and triangles. 

Students explore volume and surface area. In this math lesson, students fill boxes with cubes to identify the volume of the boxes. Students discuss area.

Learners investigate symmetry in the real world. In this geometry instructional activity, students inter-relate math and technology. They create and name a variety of polygons.
