Really Big Math

(or)

What you can do with 1,054 envelopes and a whole bunch of tape.

(Thanks to George Thornton, who taught this at NWMI)

Tetrahedra made from standard letter-size envelopes.

Put four together to form a larger tetrahedron.

Put four more together to form an even larger tetrahedron.

Take a moment to be really goofy.

Put four of the last set together to form an even larger tetrahedron.

…do it again.

…and again (with a LOT of teamwork).

And we finally finished!

Tada! (By the way, this culminated a unit on sequences and series.)
