For this three-dimensional shapes geometry lesson, learners identify geometric solids and name their properties. They define "face," "edge," and "vertex," and construct geometric solids using marshmallows as vertices and toothpicks as...

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...

Fifth graders create designs that have lines of symmetry using pretzel and marshmallows. In this symmetry design lesson, 5th graders work in groups using graph paper, rulers, and toothpicks to plan their own lines of symmetry design....

Students create various geometric shapes with their younger grade "buddy partners." They identify and discuss various geometric shapes, and using gumdrops or marshmallows and toothpicks, construct different flat and three-dimensional...

Students explore a variety of geometric shapes, name them, and list their characteristics. The shapes are transposed into structures and checked for accuracy.

Learners recognize the features of geometric shapes.  In this geometric shapes instructional activity, students listen to Captain Invincible and the Space Shapes. Learners create solid figures with marshmallows and toothpicks. ...

Students explore geometric solids. In this geometry lesson, 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...

First graders explore geometric shapes. In this math lesson, 1st graders sort shapes into groups and discuss the characteristics of the shapes. Students build geometric shapes using toothpicks and marshmallows.
