Process (How to do the activity)

 * 1) Take a cardboard sheet, draw equal squares 4 of them in a single line and select second square  and draw one above and one below , Fold each line and can get cube Take a cardboard sheet cut it into rectangular shape and cut the two congruent circles fold it and join the two circles on either sides using cello pine tape and can make a cylinder
 * 2) Ask the children to make a list of all activities in different areas of life where measurements play an important role.
 * 3) Have a discussion in the classroom regarding importance of measurements and how difficult life would be without measurements.
 * Developmental Questions (What discussion questions)
 * 1) What are congruent circles?
 * 2) What are 3D figures?

 * Evaluation (Questions for assessment of the child)
 * 1) How do you get cuboid? Which  different shapes you need ?
 * 2) Make a cone and also the frustum of cone with circles of radii 4cm and 2cm respectively
 * 3) What were the early traditional measuring modes used. Find out from your elders.
 * 4) Who formulates the standards
