Instructional Ideas

  • Allow students to check their work using this app
  • Create your own "Deep Blue” challenge. Play a game with more advanced algebra students, have half the class use the app, have the other half factor by hand.  See who wins: mind or machine.
  • Use the competition to springboard a discussion about the historical match between IBM’s Deep Blue chess-playing computer and world chess champion Garry Kasparov.



Classroom Considerations

There is a free version of this app that only supports quadratics that are factorable with integers. The user inputs the coefficients to the quadratic expression, then if the expression is factorable with integers, the app displays the answer as the product of two binomials.

 

Pros

  • Simple
Cons

  • Limited functionality
