Prime Balls
factors and multiples · identifying factors and prime factors
To identify prime factors.
Prime Balls is a Grade 6 factors game where students break a number into factors and then identify which of those factors are prime. Players draw a number tile, create factor “balls,” and capture any ball that contains a prime factor. The two-stage process keeps factor finding and prime-number identification connected rather than treating them as separate topics.
Use it for partner work when students are learning prime factorization ideas and distinguishing prime from composite factors. Ask students to explain why a factor is prime before claiming it.
