Field notes
The homepage divides activities into numbered entries, with examples spanning addition bands, triangle-angle sums, area formulas, alphabet recognition, and combinatorics with ordered placements. Many descriptions identify a school year and say learners choose among four on-screen answers; alphabet entries add audio or image cues. The interface also exposes a subject search with a retry message. One addition listing has an internal mismatch: its title says results of 50–100, while the description says 30–50.
