      4.OA.4 "Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite." This activity could be used for gifted students by providing a bigger number chart. It could also be used for ELL students by providing a smaller number chart (ex: a 50 chart). This activity could be used for younger ages by having the students identify different types of numbers. For example, the students could be searching for even numbers or odd numbers, rather than prime or composite numbers.

    Students work in pairs for this game. Each pair has a printed 100 chart. The students designate one color marker for the prime numbers, and another color marker for the composite numbers. Students take turns crossing out a composite number (1 point), circling a prime number (3 points), or passing. The player with the most points when all of the numbers are found, wins!
