The tetrahedral shape or molecular geometry around carbon atoms in organic compounds is not a familiar structure to most students. Many students have difficulty visualizing structures of molecules in three dimensions. Building a paper model of a tetrahedron and placing a molecular (ball-and-stick) model of methane into the tetrahedron can help students to understand the relationship between chemical bonding and molecular geometry.
