STEM Activities and Challenges | Toothpick 2D 3D SHAPE Mats


Use the Shape Mats to build a 3D and 3D Shape with toothpicks, playdough, or gumdrops.



Are you looking for some fun STEM ideas to incorporate into building geometry skills with 2D and 3D Shapes? I have you covered with these Build A Shape Mats! Print and laminate. Students build it with toothpicks and molding dough (you can use marshmallows or gumdrops instead), count the toothpicks, sides, vertices, and trace the words!
