Divisibility Rules
factors and multiples · divisibility · divisibility rules and factors
Use divisibility rules to determine if a number is divisible by 2, 3, 4, 5, 6, 9, or 10 [7.N(C)].
Divisibility Rules is a card game for Grades 6–8 that gives students repeated practice deciding which numbers divide evenly into a two-digit target. Players test card values against the same target number, so each turn becomes a quick application of divisibility rules rather than a long division exercise. The format keeps factors and divisibility connected while encouraging students to catch and explain errors as play continues.
Use it for small-group review when students need more fluency recognizing divisibility by common factors. Because players can challenge incorrect choices, the game naturally creates opportunities to justify why a divisor works or does not.
