Protractor Practice

Protractor Practice

Remember to estimate while using the physical Mathomat protractor

• Estimating is a personal process, that we all do differently.
• Estimating involves mentally mapping the measurement situation
• In Protractor practice Emma;
  - firstly estimates the angle size
  - then measures the wheels angle size precisely with her Mathomat
• Making an estimate of an angle is often enough by itself
• When people have trouble measuring it is often because they did not learn to build up a mental picture of what needs to be measured.
• You need to be able to see angles as representing turning
• What's New with Mathomat?
