Problem Solving Strategies

Definition of a problem:

• To truly be a problem, a mathematical quest must contain some effort of thought on the part of the solver.

As teachers, we must remember that what is a problem for some students may not be for others

Good problems include modifications that may be made for students with varying abilities.
