Divisibility Rules!

Hey, it’s Samantha. In Mrs. Walters’ class we have been learning Divisibility. All numbers are divisible by one. All even numbers are divisible by two. To see if numbers are divisible by three you can cast out three’s OR you can add all the numbers and see if the sum is divisible by three. The rule of four is if the last two numbers are divisible by four. The rule of five is if they end in a 5 or a 0. The rule of six is the number has to be divisible by 3 and 2 . Those are the Divisibility RULES!

This is Mrs. Walters’s Divisibility sign.
