Brain Teaser--Earn some Smile Savers!

You're a farmer with a boat, on one side of a river.  With you is your fox, your chicken, and a sack of grain.  You can only take one with you on your boat to cross.  If you leave the chicken alone with the grain, you can kiss your grain goodbye.  If the chicken and the fox are left alone together, let's just say you'll have a happy fox.  How do you get all three across?

When you have an answer, write it down and give it to Mrs. Parsons!  Don't share your answer and you can earn some Smile Savers!
