Marking Notes for Teachers
- Section A: 1 mark per correct answer. No partial credit.
- Section B: Each part carries 1 mark. Award mark for correct final answer. Working shown is encouraged but not required for 1-mark parts.
- Common Errors to Watch:
- Confusing "value of digit" vs "digit in place" (not tested here but relevant for whole numbers)
- Forgetting to multiply by the picture graph key (e.g., counting symbols instead of calculating value)
- Reading the wrong bar on a bar graph
- Subtraction errors when finding differences
- Not checking all categories when finding "most" or "least"
- Key Skills Assessed:
- Reading and interpreting bar graphs (vertical)
- Reading and interpreting picture graphs with scales (2, 3, 4, 5)
- Reading and interpreting tables
- Comparing quantities (more than, less than, difference)
- Finding totals (addition)
- Multi-step interpretation (e.g., Q18b requires comparing multiple days)
