Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3 dimensional...

Students explore geometric solids. In this geometry activity, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric solids...

Students measure the perimeter and area of their polygons. In this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

Third graders identify two and three dimensional shapes used in architectural designs by viewing images on the Internet.  In this geometry activity, 3rd graders create their own building designs and identify the geometric shapes...
