Divisibility Rule for 2
Imagine you are at the store looking at cookies. You know you want to buy a pack of 6 cookies and share them equally with your friend, but how do you know if you each of you will get an equal number of cookies? Knowing the divisibility rule for 2 will help you solve this dilemma without having to guess or whip out your calculator.
The divisibility rule for 2 is a short cut for figuring out if a number is divisible by 2 without having to actually solve the division problem. The rule says that any number that ends in a 0, 2, 4, 6, or 8 can be divided by 2 to produce a whole number. So, all even numbers (numbers that always end in 0, 2, 4, 6 or 8) are divisible by 2.

Applying the Divisibility Rule for 2
Now let's take this rule and solve your cookie dilemma. You have 6 cookies, which we know is an even number. With this simple piece of information, we can determine that 6 is divisible by 2. Your answer, then, is that you can share 6 cookies equally with a friend.
We can check our answer using math: 6/2 = 3 with nothing left over, so 6 is divisible by 2.
