Number Ninja
Number Ninja is for quick recall of basic sums, the number facts children in Class 1–5 need to know without counting on their fingers. Because faster answers score higher, it rewards facts that are truly memorised, and that fluency frees up attention for harder word problems later on.

- Number fact recall
- Answering at speed
