Creating apps is a fun way to write code and then share it with your friends. So, that's one of the things we are going to do this week.
First go to App Lab with Code.org.
Click on the Try it out button. You may have to sign in with a Google account, or there are other choices too.
Once you are in, you should see a picture of the Mobile Device, the Toolbox, and the Workspace. Watch the video below, and I will give you a short explanation of each of these.
