Overview
Sumdog offers a game-based online learning platform for children aged 5-14. It uses adaptive learning games for mathematics, spelling, and grammar, starting with a diagnostic test and tailoring questions to each student, with content aligned to UK, US, Canada, Australia, and New Zealand curricula; teachers and parents can monitor progress through dashboards. It stands out through broad school adoption (roughly 15% of UK schools and 10% in the US), curriculum alignment across multiple regions, and educator-focused analytics. Its goal is to close the educational attainment gap by making learning engaging and accessible.
