Explore, discuss and identify shapes that are and are not circles
Lesson details
Learning outcome
I can say if a shape is a circle or not and explain why.
Key learning points
- Describe what the outside of a circle feels like.
- Identify shapes that are circles because they are round and the outside is always an equal distance from the centre.
- Identify shapes that are not circles and explain why.
Keywords
Circle - A 2D shape that has one curved line which is always an equal distance from the centre.
Curved - A line or surface that is not straight or flat.
Centre - The middle of something.
Equal - The same.
Common misconception
Children may think that ovals are also circles.
Emphasise that the outside of a circle is always an equal distance from the centre by exploring and drawing around different cut-outs.
Teacher tip
A circle does not have any sides - we use 'curved line' rather than side. Try recreating the circle-drawing exercise on a large scale. Ask a child to stand in the 'middle', holding a piece of rope tightly. Walk round to draw a curved line with chalk.
