It is always fun to use another subscription-based site:

I look forward to these lessons as much as the students do.  As they work through activities they earn coins which enable them to buy a range of items from the online shop. After successfully completing an activity, they are able to spin the Prize Wheel and cross their fingers that it stops on the 300-point Treasure Chest.

There are learning levels suitable for Foundation level up to Year 12 covering all areas of Literacy.  Students work through activities at their own pace and can repeat activities until they reach competency. This  helps to reinforce the learning and give them a sense of achievement when they fulfil the task successfully. 

To test their skills students can compete with others within their school or from anywhere around the world.  They can also send affirmative messages to other students and test their skills in the Games Arcade.
