Often in our daily lives we need to use fair shares.  When we share a snack with our friends it is important to make sure each person gets a fair share of the snack.  

   If you and a friend share 12 crackers you need to show 2 fair shares.  The fair share may look like this.  Each person would get 6 crackers.  That would be a fair share.

Let's imagine you are sharing the 12 crackers with 2 friends.  Now you will need to show 3 fair shares.  This time the fair share would look like this.  Now the fair share would be 4 crackers for each of the 3 people sharing the crackers.

If you are having trouble with fair shares try using  "one for me and one for you".
