Have you heard of the Global Math Task Twitter Challenge? If not, you need to check it out! Students create word problems and share them using the grade level hashtag. Since I teach 5th, I use #gmttc5. Then other students around the world solve their problem and respond to the tweet. Want to get on board? It isn't too late! Check out the link for the blog to get more information and sign up for a week. You don't have to sign up to participate.
