Percent+of+Change

=Percent of Change=


 * Percent of Change**: Have students determine who the "Biggest Loser" was from a list of contestants on NBC's Biggest Loser. You can take this document and change it to be used with more current contestants. [|**The biggest loser.doc**]

- Powerpoint that uses proportions to calculate the percent of change. Problem comes up first, then proportion, then the answer in context. I change the names for every class to be names of my students. I have students work on dry erase boards and hold up their answers before I share them on the powerpoint.

- Application problems of percent increase/decrease. Some of the information isn't given "in order" (one problem gives 2007 first and 2006 second so students need to read to identify the original).
 * [[file:Around the World Percent Increase Decrease Recording Sheet.doc]]- recording sheet for activity.

- A seek and solve activity is similar to around the world in that problems are hanging up around the room. Students can start at any problem. When they find their solution, they look around the room until they find the paper that has that answer on it. Then they complete the new problem on that. I have the students record their work to the problems on the recording sheet attached below. At the top of the recording sheet I have them right the letters in the order that they complete the problems. I keep a key of the right "order" so that I know if any students answer the questions incorrectly as I walk around the room to check.

 * [[file:Percent of Change.doc]]- the same problems used in seek and solve, but given on one sheet of paper to cut into stations or just use as a source of problems.
