Solving Systems using Substitution

- powerpoint takes class through a step by step set of directions of how to solve a system using substitution...adds a situation at the end although no solution is given to that situation...

- basic examples on a worksheet (similar to powerpoint problems)...not worked out or explained

- eight practice problems...I usually glue these to file folders and have groups pass the folders around and check answers inside the folders. As an alternative I have groups put their work/solution in the folders and the last group checks all of the papers with an answer key.

- Four application problems that are "best" solved with substitution.
