Knowing the rules divisibility can be extremely helpful for students. It can help them with division, factors, prime factorization, simplifying fractions, and finding the lowest common denominator. This divisibility reference sheet will be a helpful guide for your students all year long! Post the sheet in the classroom, upload into a Flipchart/Powerpoint/Smartboard, or print for students to keep in their math notebooks or binders.
The sheet provides a definition of divisibility, uses a sentence frame to explain divisibility, and lists the divisibility rules for the numbers 2, 3, 4, 5, 6, 9, and 10. There is also an example given for each rule. Examples are given using 3-digit numbers.
This set includes two types of reference sheets. One sheet has examples provided, while the other sheet has a blank area titled “My Examples.” In this section, students can write their own example of the divisibility rule for each number. There is a full sheet and a half sheet version of each sheet.
Students are often asked to explain their thinking in math. This can be difficult for students, and often they need to be taught explicitly how to do so, especially our English learners. This reference sheet not only explains the divisibility rules, but the examples provide a strong model for providing an explanation . The sentence frame can also be used to aid students in giving explanations.
