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.
Students learn to list factor pairs through the use of a dynamic website that uses grid lines and a listing strategy. They will discover how to find the missing factor of those factor pairs ( basic facts) that they don't know through using arrays.
Using an interactive website, students use the Sieve of Eratosthenes to help them discover prime numbers, understand divisibility and inverse relationships between multiplication and division.
