Unit Summary
In this unit pupils will use knowledge of shape properties to draw, sketch and identify shapes.
Lesson Summary
You will learn to use your knowledge of shape properties to draw shapes accurately using rulers and protractors.
Key Notes
- A protractor is used to draw and measure angles accurately.
- Read the scale from zero on a protractor to draw and measure angles accurately.
- Read the scale from zero on a ruler to draw and measure accurately.
Vocabulary To Learn
- Protractor: A protractor is an instrument used in measuring or drawing angles.
Common Mistakes To Avoid
- Pupils can find protractors tricky, sometimes drawing the wrong angle because the outer scale has been used rather than the inner-scale, or vice-versa.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
A protractor is used to draw and measure angles accurately. Read the scale from zero on a protractor to draw and measure angles accurately.
2. Use this key word in a maths sentence and explain it clearly. 'Protractor'
A protractor is an instrument used in measuring or drawing angles. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils can find protractors tricky, sometimes drawing the wrong angle because the outer scale has been used rather than the inner-scale, or vice-versa. Correction: Emphasise estimation through knowledge of angle types. Model discussion of whether an angle is acute or obtuse and use this knowledge to identify which value on which scale is the measurement.
