Never Miss a Maths Lesson Again.
The teacher’s off. The lesson isn’t. 21C connects schools, tutors, and learners through a single intelligent platform that delivers curriculum-aligned maths lessons in minutes. We ensure every pupil keeps learning, no matter what.

The Maths Gap is a National Challenge. We've Built the Solution.
For Our Schools...
The Cover Crisis
Teacher absence is a systemic issue, costing schools a staggering £1.2 billion on supply staff in 2022/23 alone. This leads to inconsistent lesson quality, learning disruption, and mounting pressure on your staff.
For Our Families…
The Confidence Crisis
The pressure of GCSEs is immense. When a pupil falls behind in maths, it can knock their confidence for six, making revision feel like an uphill battle. Finding affordable, expert support that actually works is a real worry for parents.
One Platform. A Solution for Everyone.
