This is the full lesson, with two worksheets (one can be for homework), a teacher instruction page for the game activity, and the game activity page. It's introducing the concept of expanded notation using bubbles to help the students see where the place value is. The popping the bubble game has been a huge hit in my classroom and the kids love it every time they get to play! You will need small bubble containers for each partner pair (I buy the little bottles from the dollar store, they work the best and control the bubbles!) The second goes up to the ten thousands place.
Thanks so much!
