Try these angle games:

• Measuring Angles
  You rotate the protractor to place it correctly and then measure the angle. It expects precision, but if you are off by a small amount, it still says “Excellent! You measured that angle very accurately.”
• Alien Angles
  This is very cool, but challenging. You are given an angle measurement. You must set the rocket to shoot at that angle to hit the alien. Then, when you shoot the rocket into space, it tells you how precise your estimate was. You improve with practice.
• Measuring Angles
  It’s like the one on Math Playground, but requires that you move the protractor into place first before you rotate it.
