Learning the rules for divisibility is so helpful for developing good number sense, mental math skills, and math terminology! In this packet, you’ll find color and b&w versions of a poster with the rules, worksheets where students determine divisibility, H.O.T. (higher order thinking) problems, and real-life applications in word problems. There are 2 versions of each page – one for advanced students with rules for 2, 3, 4, 5, 6, 8, 9, and 10, and a simplified version with rules for 2, 5, and 10. And there are answer keys, too! - I love making students THINK!
