Cazoom Maths Teaching Resources: Full Protractor

What is the resource?

This PDF has a printable protractor. It shows a  full 360 degrees, unlike the simpler 'half' protractors used by younger learners. Best for secondary level maths.

 

Why are protractors important?

Measuring angles is way more than just school lessons:

  • Navigation: Sailors and pilots rely on accurate angles and similar tools.
  • Engineering & design: From bridges to robots, machines involve carefully planned angles.
  • 3D graphics: Even on screen, angles determine virtual object perspective.
  • Scientific tools: Microscopes, telescopes – their lens angle determines magnification.

 

Why is this resource helpful?

It supports accurate angle work and deeper understanding:

  • Full 360 degrees: Measures even large or 'reflex' angles (over 180 degrees).
  • Clear markings: Bold lines and readable scales make measuring precise.
  • Printable PDF: Great when physical protractors are scarce or for test practice.
  • Supports graphing: Essential for pie charts, circle geometry, and trigonometry.
  • Develops technique: Teaches the correct placement and reading of a protractor.

This resource supports learners in moving beyond simply measuring angles. They use it to analyse shapes, graphs, and real-world situations.
