As mathematical patterns become more complex, students' conditional reasoning skills need to be nurtured so that students continue to critique, construct, and persevere in making sense of these complexities. This article describes a mathematical task designed around the online version of the game Mastermind to safely foster conditional reasoning.

Footnotes

Use this game to nurture students' skills so they continue to critique, construct, and persevere in making sense of increasingly complex mathematical patterns.
