I created this for my students to practice the divisibility rules. Included is a slideshow stating the rules as well as providing guided practice. Also a set of cards to use for a carousel activity. I posted these numbers down the hall and had my students complete the organizer for each of the numbers. You could post them around your room if you didn't want to take them to the hall. My students really enjoyed it and it helped them internalize the rules by actively moving around. There are many ways you could use these. We used this activity to help prepare the students for finding GCF and LCM, and using them to complete more complex long division problems.
