This math activity is a great way for students to practice telling whether a number is prime or composite. Students select a card and write the number in the prime or composite number column of his/er board. The winner is the first player to fill in one whole row on their board (either 5 composite numbers or 5 prime numbers). This download comes with 3 different colorful game boards for students to write their numbers on, 36 number cards (18 prime, 18 composite numbers), and directions. Answers included on the cards so partners can self check each other.
