Clock from a Circle | Telugu | Maths with Paper Folding

This wonderful activity shows how to fold a circle into 12-equal sectors to make a clock dial face. Take a circle with a diameter of 15-cms and fold it in half to crease its diameter. Open and fold another diameter at right angles. Mark both right angled diameters with pen. This way you will also locate the center. Fold diameter tip to the center and mark both the ends. Repeat this for all the four diameter tips and you will generate 8 points. This way you will mark the circle circumference into 12-equal parts. Now, crease all these points through the center. Mark this new diameter with a pen. Repeat this for all the points that you have located. The nice thing about this activity is that you can avoid the use of the scale altogether. After dividing the circle into 12-equal sectors you can name them like the dial of a clock face. As the circle had 360-degrees so each of the 12 sectors will be just 30-degrees.
