A look at the slip slide method of factoring polynomials
Cynthia started by showing us Kahoot, a free and easy way to run a quiz game in class with students buzzing in through cell phones. Kahoot allows you to create surveys and surveys. Students load Kahoot.it through their cell phone and are asked for a PIN. Once a student enters a PIN, they join the game.

What does it mean for a decision to be democratic? What role can math play? We explore 7 different voting methods to find out (and name our math teacher circle).
So before our last meeting (Feb. 2015), we sent out an electronic survey to choose a name for our group. Teachers were asked to put the 12 choices in their order of preference from most preferred to least preferred.
Mark presented the results from the electronic survey to name our group. Here are the Results from Online Survey he created. Rather than announce a winner, Mark asked everyone to take a few minutes to look over the report. Continue reading “The Mathematics of How CAMI Got Its Name”
