In 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 edges.

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 instructional activity to...

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.

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

Learners explore geometric solids. For 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. Learners define geometric solids...

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