__FORCETOC__
=Activity - Making 3D Models=

==Estimated Time==
*1 hour

==Materials/Resources needed==
*cardboard sheet, cutter, cell opine tape, compasses , protractor ,Scale , pencil ,  
==Prerequisites/Instructions, if any==
*All the required shapes will be cut with particular measurements
==Multimedia resources==
*Arvindgupta Toys from trash for learning
==Website interactives/ links/ simulations/ Geogebra Applets==
==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<br>
2) 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<br>

*Ask the children to make a list of all activities in different areas of life where measurements play an important role.<br>
*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?
3) What are polygons

Why measure ?<br>
#How do we measure ?<br>
#What are the measuring modes and units seen at the market, Hospital, Chemist laboratories, Gold shop, Tailors, Bakeries, Petrol bunks, water tankers, milk vendors, contractors, kitchen, airport, and so on.?
==Evaluation (Questions for assessment of the child)==
1) How do you get cuboid? Which  different shapes you need ?
Question corner 
Make a cone and also the frustum of cone with circles of radii 4cm and 2cm respectively


==Question Corner==
#What were the early traditional measuring modes used. Find out from your elders.<br>
#Who formulates the standards<br>
