Measuring and drawing angles for 11+ Maths
Measuring and drawing angles is a key part of the 11+ Maths syllabus. Children need to feel confident with using a protractor, reading the correct scale, and drawing angles accurately. This guide offers practical steps for parents to support practice at home.
Understanding how to measure angles
Angles measure the amount of turn between two lines that meet at a point. We use degrees to describe angles. A right angle is 90 degrees, a straight line is 180 degrees, and a full turn is 360 degrees. A protractor is the main tool for measuring and drawing angles.
Common mistakes to avoid
Children often misread the scale on a protractor, especially as most have two sets of numbers. Always check that the baseline of the protractor is lined up with one arm of the angle and that the centre is placed exactly on the vertex. Use the scale that starts at 0 on the aligned arm.
Worked example
Drawing a 65 degree angle
Step 1: Draw a straight baseline with a ruler and mark one end as the vertex.
Step 2: Place the centre of the protractor exactly on the vertex. Line up the baseline of the protractor with your drawn line.
Step 3: Find 65 on the protractor scale that starts at 0 on your baseline. Make a small mark at this point.
Step 4: Remove the protractor and use a ruler to draw a straight line from the vertex through the 65 degree mark.
The correct answer is a 65 degree angle drawn from the baseline.
Key insight: Practising with a real protractor helps children spot the difference between the inner and outer scales. Always double check which scale you are using before reading or marking the angle.
Building confidence through practice
Regular practice with both measuring and drawing angles builds accuracy and speed. Try measuring angles in everyday objects, or set up simple drawing exercises. Encourage your child to check their answers by measuring their own drawn angles.
