3rd – 6th Grade
The Common Core for 4th Grade states that students should be able to “find all factor pairs for a whole number in the range of 1-100” … and “determine whether a given number in the range of 1-100 is prime or composite.”
This Finding Factors Freebie is what I use to teach my 4th graders how to find all the factors of “Today’s Number” which is a routine we do as part of my SMARTBoard Math Calendar. Today’s Number is always whatever day of school it is, and we make an organized factor list, starting with 1 and the number. My students become experts on prime and composite numbers, as well as the difference between factors and multiples, thanks to this daily repetition.
