Ambar, who attends Pakeman primary school in north London, is one of nearly 4,000 primary school children in Britain signed up for weekly one-to-one maths sessions with tutors based in India and Sri Lanka. The lessons, provided by a company called Third Space Learning, are targeted at pupils struggling with maths – particularly those from disadvantaged backgrounds.

From next year, the platform will become one of the first examples of artificial intelligence (AI) software being used to monitor, and ideally improve, teaching.
