Activities

[Author - Kripa S]

1. Take a cardpaper piece and draw a circle of any radius of your choice. Divide the circle into 8 equal parts. Shade each portion with a different colour (yellow, orange, red, pink, green, blue, violet, dark colour). Push a pen refill or a stick and rotate the sheet. See the colour of the rotating sheet and discuss why you see that colour.

2. Make teams of 4 students. Each team must draw a circle and divide it in 12 equal parts. Each team must make chits of paper and write these fractions : 1/12, 2,12,3/12,4/12,5/12,6/12.....11/12,1/2,1/3,1/4,1/6. Shuffle these chits. One students picks out one chit and shades those many parts of circle. Then the next student will pick out another chit and shade those many parts. Repeat this step till the circle is fully shaded. The team which shades the circle first wins.

3. A game between two teams. One team will tell a measurement of length or weight in m/ g and other team has to tell the measurement in km/ kg with proper decimals.
