This unit focused on inductive and deductive reasoning.  Students
were answering delving in to logical arguments and how to form them. 
This unit was a great introduction to writing formal proofs by starting
with logic puzzles and games.  Students completed a benchmark project
to complete this unit.  Their projects included writing 3 types of
puzzles, a color-square puzzle, a crossword puzzle and a puzzle of
their choice.  Then the students exchanged puzzles and solved their
partner's puzzles.  The student who was solving the puzzles had to use
syllogisms and conditional statements to prove the solution.  Their
written proofs were submitted with their puzzles in a portfolio format.
