Unit Summary
In this unit pupils will interpret and construct pie charts and line graphs. They will read scales linked to fractions angles percentages and understanding proportional relationships.
Lesson Summary
You will learn to construct pie charts using angles, fractions and percentages.
Key Notes
- A pie chart is another way of presenting data representing parts of a whole.
- Pie charts can be constructed using knowledge of angles and fractions.
- A protractor is used to accurately measure each angle.
Vocabulary To Learn
- Pie chart: A pie chart is a circular graph where sectors represent different groups in proportion to each other.
- Sector: A sector is a part, or 'pie-slice' part, of a pie chart.
Common Mistakes To Avoid
- Pupils may make mistakes measuring with a protractor, reading the wrong scale to get a measurement.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
A pie chart is another way of presenting data representing parts of a whole. Pie charts can be constructed using knowledge of angles and fractions.
2. Use this key word in a maths sentence and explain it clearly. 'Pie chart'
A pie chart is a circular graph where sectors represent different groups in proportion to each other. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may make mistakes measuring with a protractor, reading the wrong scale to get a measurement. Correction: Encourage pupils to check that each answer is sensible. Is the angle greater or less than a right angle? Have they drawn an angle greater/less than a right angle? Do all the angles add up to a sum of 360°?
