Question

O
INTERNAL ASSESSMENT
A minimum of two assignments are to be done during the year as prescribed by the teacher.
Suggested Assignments
• Conduct a survey of a group of students and present it graphically – height, weight, number of
family members, pocket money, etc.
• Planning delivery routes for a postman/milkman.
• Running a tuck shop/canteen.
Study ways of raising loan to buy a car or house, e.g., bank loan or purchase a refrigerator or a
television set through hire purchase.
• Cutting a circle into equal sections of a small central angle to find the area of a circle by using
the formula A = tr2.
• To use flat cutouts to form cube, cuboids and pyramids to obtain formulae for volume and total
surface area.
Draw a circle of radius r on a 12 cm graph paper, and then on a 2 mm graph paper. Estimate the
area enclosed in each case by actually counting the squares. Now try out with circles of different
radii. Establish the pattern, if any, between the two observed values and the theoretical value
(area = tru). Any modifications?​
