Free Printable Divisibility Rules Charts
I don’t remember ever learning any rules about divisibility when I was in school. I’m still not sure whether I simply missed them, or whether they were never actually taught.
Now, more than twenty years after graduating from high school, I have been learning some basic divisibility rules along with my kids. Major timesavers!

My children are learning these rules also, makes division much easier. I think I slightly remember these rules in my 8th grade year when I was beginning Pre Algebra. I said think. That was a l-o-n-g time ago.
I remember my dad (chem major with math minor) trying to teach some of these rules to me when I was in upper elementary (30+ years ago!). For me, figuring out the rules seemed to take as long as just trial and error division, so I just forgot them – except the 2, 5, and 10 rules. I have a rule-loving fourth grader who may appreciate these rules. Worth a try to introduce to him! Thanks for the freebie!!
