Percent Increase and Decrease

Here’s a sample lesson on Percent Increase and Decrease designed for a 52-minute Pre-Algebra class.

1.  Start by watching the video on ‘Percent Increase’.  Make sure that students have the handout so that they don’t have to write down the application problem.
2.  Have students work on the two ‘Group Work’ problems on percent increase.
3.  Follow the same process for ‘Percent Decrease’.
4.  Have the students do the Percent Increase and Decrease ‘Matching Activity’.  You need to have the tiles cut apart for them already.  If there is not enough time to complete this in class (There usually isn’t), suggest that the students take the activity home.  If you wish, have the students bring the completed matches back to the next class for credit.

A few months ago I had students in my Basic College Math class create a game about fractions.  One student created “Fraction Bingo”.  I decided to search the web to see if there were printable bingo sheets available.  Well, there were, along with some other activities that I found on the same website from Holt, Rinehart, and Winston.  And below is a list of a few of my favorite ones, appropriate for college-level basic math classes (organized by topic):
