LIST OF ACTIVITIES FOR PRACTICUM RELATED TO TEACHING OF MATHEMATICS

 SL.No Activity Class 1. Locate some of the irrational numbers(2,3,5) on the number line Class IX 2. Construction of “square root spiral” Class IX 3. Introduction of coordinate geometry by an activity “Seating plan” Class IX 4. Street Plan: A city has two main roads which cross each other at the centre of the city. These two roads are along the North-South direction and East-West direction. All the other streets of the city run parallel to these roads and are 200m apart. There are 5 streets in each direction. Using 1cm= 200m, draw a model of the city. Represent the roads/ streets by single lines. Class IX 5. In any triangle, the side opposite to the larger (greater) angle is longer. Theorem 7.7 (Show/prove practically) Class IX 6. Parallelograms on the same base and between the same parallels are equal in area. Theorem 9.1 (Prove practically) Class IX 7. Construction of a quadrilateral when the lengths of two adjacent side and the measure of any three angles are given Class - VIII 8. Construction of a triangle, if perimeter and two base angles are given. Construction 11.6 Class IX 9. Determine Surface Area of a right Circular Cone. Class IX 10. Determine Surface Area of a Sphere Class IX 11. Determine Volume of a Right Circular Cone Class IX 12. Graphical Solution of a Pair of Linear Equations in Two Variables. Class X 13. If a line divides any two side of a triangle in the same ratio, the line is parallel to the third side. Theorem 6.2 (Prove practically) Class X 14. If a line-segment drawn from the vertex of an angle of a triangle to its opposite side divides it in the ratio of the sides containing the angle, then the line segment bisects the angle. Property 8.7 (prove practically) Class X 15. Equal chords of a circle ( or of congruent circles) are equidistant from the centre (or centres) Theorem 10.6 (Prove practically) Class X 16. If a line- segment joining two points subtends equal angles at two other points lying on the same side of the line containing the line- segment, the four points lie on a circle, Property 9.11 (Prove practically) Class X 17. Draw a tengent to a circle from a point outside the circle without using the centre of the circle. Construction 11.1 Class X 18. Draw tangents to a circle from a point outside the circle without using its centre. Construction 11.3 Class X 19. Collect data regarding HSLC result ( at least for three years) from a secondary school and represent the data in the form of a composite bar diagram showing numbers of students securing 1st , 2nd,3rd division. 20. Administer an achievement test in Class – X and draw a frequency polygon to present the scores obtained in the test.
