Students work
collaboratively on solving a mathematics problem. Working in a team
allows for communication of mathematical ideas and solution strategies
and the connections among different representations. . How to use it: Students will use Polya's 4 steps to problem solving. 1) Understand the problem. 2) Choose a strategy ( more than one
among your group) 3) Solve and compare strategies. 4) Look back and be ready to share.
