### Probability

I decided to do a search for free apps that cover probability.  I found one that is geared for 6th grade, has both a free and paid version and has a nice review of the basics.  Its 6th Grade Learning Games for Math and Language by Kevin Bradford.  When you download the app, there are only 3 games unlocked.  If you want all 10, you need to pay \$1.99 to unlock all the games.

The second game deals with probability and statistics.  The idea behind the game is that you answer 5 questions to get the rocks you will use to knock down the structure to get points.  Each rock represents a chance to knock down the structure and gain points.
Once you have earned the rocks, you use a catapult to fire the rocks at the structure. The more damage you do to the structure, the more points you earn.  You can repeat to try again to earn additional points.

The questions themselves deal with the probability of a certain color in a spinner, median, mode, and range.  Basics that most students need to learn and know for mathematics.

I will probably use this in my pre-algebra class as a way to cover some of the probability without having to actually take time to teach it.  This is a good way for students to review some of the basics so when I do teach probability, they will be ready.

Tomorrow, I"ll review the number sense game in this app.
