In the Playing with Parity Circle, students learn about parity through playing games and learning magic tricks. The Circle is an opportunity for students to play with and explore parity – to deepen their understanding of what it means for a number to be even or to be odd, and to draw connections between the games and the games’ various uses of parity as a mathematical tool and concept.
