Product Description
This is a matching puzzle, also known as a Tarsia. Please see my other puzzles, most of which deal with trigonometry and calculus, with some precalculus thrown in, too.

There are two types of expressions, complex numbers in a + bi form, and multiplication or division expressions yet to be reduced to a + bi form. Students match unreduced expressions with the proper reduced expressions in a + bi form. The final shape is a parallelogram.

Instructions (time is approximately 30 - 45 minutes):

1. Print each puzzle (two pages), using single-sided printing.

2. Students cut out all triangles, from each of the two sheets.

3. Students match un-reduced expressions to their equivalent reduced forms, edge to edge, like one would put together a jigsaw puzzle. The puzzle can be put together in only one way, as each expression, reduced or otherwise, occurs only once.

4. The final shape is a parallelogram.
