Do children need to do the lessons with an adult?

Each lesson has a pre-recorded video with a teacher who takes pupils through each section step-by-step. Each lesson can be paused and rewound to help students learn at their own pace.

The level of supervision has been designed to be minimal (although this will depend on the age of the learner). It's important to note however that resources have been created to complement existing teaching, rather than to replace contact with teachers.
