The Number skills project is dedicated to designing children’s KS2 maths apps, self-contained, single-file, offline HTML apps built around a learn-then-test pedagogy, with per-device profiles, local progress saving, and a touch-first British-English interface. Each app is simply downloaded and opened in any web browser to run, with no installation required. The current build in the project is Fact Masters — Number & Geography, covering number skills including Number Facts, Times Tables, Number Bonds, Doubling & Halving, Square Numbers, Rounding, Fractions of Amounts, Negative Numbers and Money & Change, alongside geography skills such as Continents, Oceans, Capitals, Compass Points, Flags, Landmarks, and UK Rivers & Mountains. To keep pupils engaged, it adds named profiles, badges, a leaderboard, streaks, and a printable achievement certificate.
