Marshmallow Figures

Students make observations and classify geometric solids by characteristics. In this examining geometric solids lesson, students classify three-dimensional geometric solids. Students examine why classification of geometric solids is...

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.

Fourth graders classify geometric shapes and figures. In this geometry lesson, 4th graders use cut-outs of shapes and identify the faces and sides of each shape. Students use marshmallows and toothpicks to construct various shapes.

Students explore perimeter, area and volume. Using geoboards, toothpicks, and marshmallows, students create specific shapes. They are directed to use formulas to find the volume, area, and perimeter of the created shapes. In groups,...

Students compare and contrast the characteristics of prisms and pyramids. In groups, they are given different colored construction paper to make rectanglar prisms. They identify the shapes of the faces and record the number of faces,...

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

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...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Scholars show what they know about types of triangles with a hands-on activity that challenges them to build models using toothpicks. Following a whole-class discussion and brief presentation, small groups gather to form shapes and...

Fifth graders use their arm, toothpicks, and marshmallows to create lines, segments, and rays. In this lines, segments, and rays lesson plan, 5th graders learn how these appear on a plane.
