Here is a fun way to let your students practice proportions. There are 15 word problems with answers. Some questions require students to do some basic converting prior to setting up and solving the proportion.
Divide students into 2 teams. One person from each team races to work the problem. The person who solves the proportion correctly can choose to keep the point that was earned for his or her team, or make a deal. If the students chooses to make a deal, they draw out of the envelope in hopes they can get extra points for their team. The team with the most points wins!
"The Deals" are included on the last slide of the presentation. Simply cut those in strips and place them in an envelope. The deals include added points, subtracted points, and other silly things (Zonks!) just like the game show.
