Lily's kindergarten teacher sent home a homework assignment over the break that I loved! Storybird is a site where you and your kids can go and write your own stories (and it's all free!).
They have picture kits to choose from, you write the story and print them off into fabulous little books. The girls have loved making up their own stories and showing off their books. I love that they are using creativity and learning all while having fun. It's definitely worth checking out.
