A good way to start is by watching the videos from the tabs at the top of this site. Watch the videos and do some math on your own using the concepts and strategies presented. Check in here for suggestions about math explorations, resources, and to see what others are posting and asking about. When you are ready, delve into some more math after you do a number talks at home. Have fun!
