Common Core emphasizes the need to develop mental math strategies with students. Understanding the divisibility rules will allow students to begin the process of making math connections and help to strengthen mental math skills.
My 5th grade students had never been introduced to most of these divisibility rules, so I chose to teach them one at a time. Slowly, over the course of a semester, I introduced each one, giving them time to practice and master each before moving on to the next.
Some are obviously easier than others, so I chose to start with those (divisibility rules 2, 5, 10) first. I did not teach the rules in numerical order, but rather by order of difficulty.
This pack includes 10 single-flap, Individual Divisibility Rules Foldables. Rules include, divisibility rule for 2, 3, 4, 5, 6, 7, 9, 10, 11, and 12. The inside of all of these foldables could be enlarged and used as a poster for your classroom. To learn how to make a poster be sure to visit my Making Posters post.
