Logic roots makes products to make learning fun for primary school students. Especially subjects like maths, by using games to illustrate principles and theories. I did some user research and the interaction design (wireframes) as well as the visual design for the pages.
Some features were: kids could choose an Avatar which were cartoon characters, etc, which even they could upload. Leaderboards with those chosen avatars keeping the learning competitive. Dashboards to monitor progress in different subjects and so on. More than that, how to get a new user to start using the product and then get them to register, was tackled in a few different ways. One being letting the user start using (that is playing, seeing the dashboard, etc). You can see a few screenshots here
