- The longest chord in any circle is its diameter.
- Any number of chords can be drawn in a circle.
Estimated Time
20 minutes.
Prerequisites/Instructions, prior preparations, if any
The students should have the knowledge of circle, diameter, circumference and line segment.
Instruct the children to get cut circles ready:
Materials/ Resources needed
Non digital: Circles cut from white paper, colour pencils, scale.
Process (How to do the activity)
- Fold the circle at different points and try to form the smallest and biggest chords.
- What is the difference between the chord and diameter.
- Evaluation:
- Observe to see if the children are able to fold and mark the chord accurately.
- Name the chord that passes through the center of the circle.
- What happens to the length of the chord as it moves away from the centre?
