Rounding the wooden arrow in the circle, and find the cube root of given no.

Learning Outcomes

 

1) Students will be able to understand relationship of cube number and it's cube root.

2) Students will be able to find cube root by prime factorisation.

3) Students will be able to connect this topic to their daily life and solved the arising questions.

Description Of Activity

1) Draw a circle in playground and divided it into 12 equal parts.

2) write cubic no. like as (cube root of 1) , (cube root of 8), (cube root of 27), (cube root of 64), (cube root of 125), (cube root of 216), (cube root of 343), (cube root of  512), (cube root of 729), (cube root of 1000), ( cube root of 1331), (cube root of 1728) in every part of the circle .

3) Fix a wooden strip whose shape like as arrow (➡) on the center of the circle with help of nail.                    4) Now class divided into 12 group.                                                                                          5) 5)one student of every group come and rounding the wooden strip.

6) where this arrow(➡) stop, remaining students note that cubic no. and find the cube root of that no. by prime factorisation.

7) After  get cube root of that no., it is written in the circle below  that cubic no.

8) This procedure continue for every group.

9) Which group take minimum time, they will win the game.

Variations

 

Students also learn about to use a visual understanding to make connection to volume  as application of cube and cube root.

Coaching Tips

 

Encourage the students to give more example of cube and cube root by giving them task to find sides of different solid cubes with given volume.
