NumihanaA little space for maths
Numihana is a free worksheet and interactive practice platform. Maths Method Lab is its feature for exploring calculation methods.
The service includes source-linked activities across England Years 1–6, including number, arithmetic, fractions, measurement, geometry and data. Practical lessons also support the wider statutory targets; automatic answer checks and adult observations do not certify mastery. No other curriculum is currently supported.
There are no pupil accounts, paid APIs, advertisements or learner analytics. Optional aggregate measurement is limited to adult information and worksheet catalogue pages. The application is static and calculations run in your browser.
