Challenge and encourage your students to take a more active role in their mathematics class by utilizing these puzzles, logic problems, and problem-solving exercises. These counterintuitive math problems will allow you to actively breach the wall of negativity surrounding mathematics. Teaching that incorporates students' intuitive solutions can increase learning, especially when combined with opportunities for student interaction, discussion, and interdisciplinary learning. The dissonance that these problems create is part of the fun inherent in these problems and activities. Adolescents tend to be passionate about defending that which they see as right-even students who are usually reticent to participate will find themselves being drawn out by these challenges.
