This lesson is a themed application for use before, after, or during the lesson on solving literal equations in one variable. You could also extend this lesson by deleting the information in the tables and allowing students to research them on the internet (which is what I did). I try to create "lab" cooperative activities to last no more than 45 minutes, or I break them into parts.
I try to personalize my lessons using local towns, etc. If you would like to edit this, please choose the word version.
