There are hundreds of apps and websites to work on your skills at home, for example:
Your computer may need two pieces of software to run these games, one is called "Java" and the other is called "Flash Player".
These are already on most Windows computers, but are free to download if your computer doesn't have them already. Please ask your parents and the computer's owner for permission before downloading this software on to the computer.
