divisibility+rules

Oct./6/10 Yesterday on the 5 of October in mastery extension we learned about divisibility rules I think divisibility rules are:


 * 1) A reliable way to find out if a number is divisible by another number
 * 2) Easy to learn nothing complicated
 * 3) Fun and a good homework tool
 * 4) Works every time you just have to do it correctly
 * 5) If you forget it is a challenge to figure it out again but a good thinking problem

Since Mrs. White forget the fours we had to figure it out witch was hard but fun.
