Do the activities on this page in order. The easier activities are at the top, and they get more difficult as you go down the page. Spend as much time on each activity as you want to. If you find an activity to be difficult, you should repeat it several times until it gets easier. Keep a pen and pencil nearby so you can write down any new things that you learn.
