1)Write some fractions on the board and show the kids a big pack of chocolate chip cookies, boy does that get their attention and stir up some excitement!
2)Let the kids vote for which fraction of a cookie they want. Now at this point I have not explained what a fraction is so they have no idea what the numbers mean. I just tell them these are fractions, they're my favorite part of math ever, and we're going to be learning about them. I also tell them that nobody will get a whole cookie to themselves they will only get a piece so this helps them realize that a fraction is just a piece.
3)Cut up the cookies (using a doc. camera so they can all see) and this is when we really talk about what a fraction is and what the numbers mean. We compare the size of one half, one fourth, and one eighth. Being the nice teacher that I am, I give them a chance to change their mind and vote again and wouldn't you know, they all want one half!
