What we check
Checks cover the math in each problem, its answer, the allowed number ranges, and whether the same saved worksheet can be opened again.
Answer keys
Problems and answers come from the same operation rules. Browser tests render representative worksheet and answer-key pages so both sides can be reviewed.
Page layout
New visual skills are reviewed at normal and compact layouts for clipping, overlap, spacing, alignment, legibility, and meaning in grayscale.
Automated checks
Automated tests cover operation logic, exact answers, duplicate handling, number ranges, reproducible seeds, and saved generator versions.
Report a mistake
If a question or answer looks wrong, report the skill, problem, and answer you expected. Include the worksheet code when available, but do not include student names or other personal information.
