Tips for using this site
The activities on this site may take about 20 to 30 minutes to work through. You may wish to split this over a number of online sessions.
If you're new to this site
If you'd like to save what you do in a session, simply click on the 'Save' icon at the top right-hand corner of the screen. You'll be asked for a username and password.
As you work through the activities, your progress will be saved whenever you click 'Next' at the bottom of the screen.
When you wish to finish a session, click on the 'Logout' icon at the top right-hand corner of the page. This is important if you're on a shared computer.
If you're returning to this site
If you've already set up a username and want to open up a previous session, simply click on the 'Open' button at the top right-hand corner of the page. Enter your username and password to retrieve what you've done so far.
If you're confident you can work through all the activities in a single session and don't want to save your progress between online sessions, you don't have to set up a username. Please note, however, that your answers won't be saved beyond your current session.
