Describe rotations using the standard unit of degrees when compared to a right angle
I can describe rotations using the standard unit of degrees when compared to a right angle.
Lesson details
Key learning points
- Some objects rotate or spin and this is measured in degrees
- Rotation can be more than a right angle >90 degrees
- Rotation can be less than a right angle <90 degrees
Keywords
Degrees - A degree is a unit of measure for angles.
Estimate - To estimate is to find a value that is close enough to the right answer, usually with some thought or calculation involved.
Rotation - A rotation is a circular movement around a fixed point.
Common misconception
Objects rotate only either less than a full turn or more than a full turn.
Take time to discuss the purpose of the object in question and clarify the difference between what an object should do and could do.
Encourage pupils to find examples of rotating objects in their own settings and explore the different starting positions of each angle, generalising that an angle can start from any point.
