Polyominoes and polytans provide natural follow-ups to the tangrams. Let
me know whether you have interlocking cubes, (or for that matter any sort
of cubes or tiles, or graph paper), and I can suggest some interesting
activities.

The best ways to make polyhedra (in my limited experience) is with tabbed
polygons, connecting them with rubber bands (this is hard to describe
without pictures, but you should be able to find someone who knows how to
do it?) or with flexible straw polygons, attached to each other with tape.
Both forms discourage perfectionism and encourage exploration.

It's OK -- you learned something, and they had fun!
