WebNov 12, 2009 · This is a tasty way to provide some hands on geometry practice for 5th grade. Playing with food is always fun, and this consumable project will be a sweet success for your students, as they use gumdrops and toothpicks to construct edible models of … WebIn geometry, a polyhedron is a three-dimensional object with flat polygonal faces, sharp corners and straight edges. Each side is a flat surface and is without any curved surfaces. The word comes from the Greek 'poly' (stem of many) + 'hedron' (face). So, a polyhedron basically means 'many faced geometric shape.'. solving 5x5 lights out
