Give a dog a bone!

We learned a new math game online.  We can play it on our smart board.  We are teaching each other strategies for finding the hidden numbers. We are really trying to be brave and share our thinking because it helps others even if we don't get the answer right we are still helping others learn.  You could try the game at home 

You can find it on the web at 

www.oswego.org 

It is called Dogbone.
