2) Count out loud.
3) Practice a few times to understand the method.
Participation is key to learning how to subtract. Print out the worksheet and follow along with the video, or try and do the worksheet using the method after you watch the video. The more you use your fingers and count out loud, the better. The more you practice with the video, the more the method will make sense. Have fun! You can even wear gloves while you count!
