Elf Fact Families

Hi friends!  This will be a quick post because I am currently in Columbus for the Ohio Literacy Conference!  I am learning so many new & exciting things that I can't wait to implement into my classroom. 

Here is a quick & easy math tub for practicing fact families that my mice are playing while the cat's away.  Sorry I don't have any pictures of it in use -- I'm not there to take any!  :)  Enjoy!
