Adding by breaking down to 10

Today we will start using our number sense and knowledge of 10 to add numbers to 20. This week the focus will be on breaking down to 10 and then adding the ones. I have made a short video to help you at home know what we are doing in class. Keep checking back for more videos as we learn more strategies. This may seem like a lot of steps for an easy math problem, but we are learning strategies now with easy numbers so that studnets can start applying them to bigger numbers.
