May + June = 40 + 36 = 76mm

Percentage = (76 ÷ 180) × 100% = 42.2%

Part (c): Fraction of annual target

Fraction = 180 ÷ 1200 = 3/20 of the annual target

Final Answers:

(a) Mean monthly rainfall: 30mm

(b) 42.2% of rainfall occurred in May and June

(c) 3/20 of the annual target was reached

Questions & Answers

Question: How do I know if I'm reading the bar graph correctly for GCSE questions? Sometimes the bars don't land exactly on the lines.

Answer: Here's how to handle approximate values on bar graphs:

  • Read precisely: Look at exactly where the top of the bar ends
  • Estimate carefully: If between two values, determine the fraction of the distance
  • Use context: Consider what values make sense in the given scenario
  • Be consistent: Use the same estimation method throughout
  • Check scale: Note the interval size on the y-axis

For example, if the y-axis goes from 0 to 10 in steps of 2, and a bar ends halfway between 6 and 8, you would estimate it as 7. Always aim for the most accurate reading possible!

Question: What are the most important things my child should focus on when practicing bar graph questions for GCSE?

Answer: Focus on these key areas for GCSE bar graph success:

  • Accurate reading: Practice reading exact values from various scales
  • Multiple operations: Work on problems requiring addition, subtraction, multiplication, division
  • Word problems: Translate scenarios into mathematical operations
  • Working presentation: Show methods clearly to earn method marks
  • Unit awareness: Include appropriate units in answers
  • Time management: Practice under timed conditions

Regular practice with past paper questions is the most effective preparation method!

Question: How can I check if my bar graph answers are reasonable during the exam?

Answer: Use these verification techniques:

  • Visual check: Compare your answer to the relative heights of bars
  • Reasonableness: Does the answer make sense in the real-world context?
  • Scale verification: Is your answer within the range shown on the y-axis?
  • Relationship check: Does your answer align with visible patterns?
  • Arithmetic review: Double-check calculations if time permits

For example, if you calculate that someone scored 15 goals when the tallest bar shows 10, you know something is wrong and need to reconsider your approach!
