This post may contain affiliate links.
Turn geometry into a hands-on STEM experience with this Marshmallow & Toothpick Geometry set! Students construct both 2D and 3D shapes using marshmallows (or gumdrops) and toothpicks, then count edges, faces, and vertices—reinforcing essential math vocabulary and spatial reasoning.
What’s Included
-
22 shape cards featuring 10 two-dimensional and 12 three-dimensional shapes
-
Each card shows the exact number of marshmallows & toothpicks needed, plus a preview graphic
Ideal For:
-
Grades PreK–6 — flexible enough for early learners and advanced students
-
Math centers, STEM stations, homeschool enrichment
-
Reinforcing geometry terms, Euler’s Formula, and spatial awareness
-
Hands-on exploration and critical thinking in small groups
How to Use:
-
Print shape cards and student recording sheets.
-
Provide marshmallows (or alternatives) and toothpicks.
-
Use as a center, cooperative STEM challenge, or whole-class demonstration.
-
Extension idea: Apply Euler’s Formula (Vertices – Edges + Faces = 2) to 3D shapes.
Benefits:
-
Multisensory learning strengthens retention
-
Enhances critical thinking and problem-solving
-
Supports STEM skills like measurement, collaboration, and observation
-
Great for flexible grouping and recreated across grade levels
