Videos and lessons to help Grade 4 students learn to 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.

Common Core: 4.OA.4

Suggested Learning Targets

• I can define factors and multiples and list the factor pairs of any number between 1 and 100.
• I can define prime and composition numbers and determine if a number is prime or composite.
• I can determine if a number is a multiple of 2, 3, 4, 5, 6, 7 or 10 by using divisibility rules.
