A useful worksheet report should connect a result to the actual question, the child’s working and a next practice choice. It should distinguish what was observed from what still needs checking.
Ask for evidence behind a topic label
“Percentage needs work” is only a starting signal. Ask which questions were attempted, how many were missed and whether the working shows the same step going wrong. A single error does not establish a persistent weakness.
A Primary 5 example: the discount is not the final price
An item costs 120 dollars before a 15% discount. The discount is 120 ÷ 100 × 15 = 18 dollars. The amount paid is 120 − 18 = 102 dollars. If a child writes 18 dollars as the final answer, first ask whether that number represents the saving or the price. The percentage calculation may already be correct.
For a fresh attempt, an item costing 80 dollars with a 15% discount has a 12 dollars saving and a 68 dollars sale price. Use the Primary 5 percentage guide to revisit the distinction.
Turn the observation into a review decision
- Record the question and what the child was trying to find.
- Separate the percentage calculation from interpreting “amount paid”.
- Ask the child to explain the final answer with its dollar unit.
- Use a fresh example later before describing the pattern as resolved.
What Zairoo’s worksheet analysis applies to
Use the dedicated worksheet analysis tool with its supported Zairoo worksheet sets from the worksheet page. This is separate from topic practice and question guidance. It does not mean any uploaded school worksheet can be marked in the Parent or Child portal. General completed-work marking in those portals is still coming soon.
Read the report alongside the child’s working. It cannot establish anxiety, motivation or a learning diagnosis from a score.
For observations without a worksheet report
Use the parent observation routine after practice when you are keeping your own short record rather than interpreting a tool’s report.
Sources and example notes
The MOE Primary Mathematics syllabus (October 2025) supports the topic-level references. These original practice examples are not official assessment questions.
The EEF mathematics guidance recommends using assessment to inform teaching. Its Key Stages 2–3 context is England; it does not establish Singapore levels or Zairoo outcomes.
