10. Protto: Problem Lotto
Played individually, or with partners, this competitive game involves creative thinking and teaches students that problems often have more than one solution, and that sometimes one solution can be used for more multiple problems.
Students divide one sheet of paper into four quadrants by drawing one vertical and horizontal line. Each quadrant represents a problem that the students have selected from a designated list of problems. The teacher may randomly draw cards or have students draw blindly from a set of cards that have solutions printed on them. If a solution fits a problem listed in one of the students’ quadrants, they may write the solution in that quadrant. If the solution fits for more than one problem quadrant, the student may write it in each quadrant where it applies. The first student to fill out all four quadrants and shout ‘Protto!’ is the winner. The teacher serves as the games judge. And now, let’s see what else we have in our list of problem solving activities for high school students.
