Run and Jump

Learning Outcomes

1. Students could be able to understand the concept of circle
2. Center of the circle
3. Radius and Diameter of the circle
4. Concentric circles
5. Circumference of the circle
6. Ratio of the circumference and Diameter/radius of the circle

Description Of Activity

How to Play 

1. There are several concentric circles drawn on the floor or ground with different diameters 1 ft, 2 ft, 3 ft, 4 ft, 6 ft etc. And small circles or squares are on each circle as in the picture. 
2. Depending on the number of students number of concentric circles can be increased. The number of small circles is increased by three with increase of diameter like 1, 3, 6, 9, 12, 15.so on.

 Method of playing

1. If there are six concentric circles then 21 students can start the game. They run around the outer most circle while music is played. 
2. When the music stops, they jump inward occupy each small circle or square on the sixth circle. Eighteen of them will successfully occupy the circles and three children who couldn't get the circle will have to leave the game. 
3. This continues for five more rounds and in each round three students will be eliminated. Finally one student remains and he is the winner.

Variations

If more number of students interested to play, next batch can start playing on the same floor after the first batch finishes two or three rounds.  Care must be taken by the teacher or PET to avoid the students pushing or pulling each other while occupying the circles. Concentric Circles and other small circles can be drawn permanently on a cement floor or temporarily on any floor by using chalk powder. 

Coaching Tips

1. Teacher explains concept of radius and diameter of the circle while drawing the concentric circles.
2. The ratio of circumference to the diameter of the circle is equal to π .
3. Circumference/Diameter = π   (π = 3.14 approximately)
4. Hence this games will develop a concrete idea on the concept that
5. Circumference is approximately equal to three times the diameter of the circle.

Equipment/Material Required

Chalk powder or white (colour paint also can be used) paint, Rope for for drawing circles, music system or wistle
