S.No. Class Title of TLM Brief Description Video of TLM Explanation by self or using it with Students Prepared By
1. Secondary Theorem based on circle The angle subtended by an Arc on the centre is double the angle subtended by
the Arc on the remaining part of the circumference		 Link Preeti G Co-ed SSS Barwala (1310161)
2. Secondary Co-ordinate Geometry Mode of Activity : Individual /Groups
Objectives:
1)To make learner understand basics of Cartesian Plane
2) To develop better understanding of coordinates in a 2D plane
3) To locate a given point in Cartesian plane with the help of abscissa and ordinate
4) To identify x and y coordinates of a given point
5) To familiarise the learner with the Cartesian Plane (Rene Descartes, Axes, Origin, Abscissa, Ordinate, Quadrants)
6. Distance formula
7. Mirror image
8. Midpoint formula
9. Slope of a line
10. Day to day life Applications
Material Required cardboard
Thread , Board Pins, Marker, sheets, small toys
Steps:
1) We can introduce by history of coordinate geometry by telling them intersting story of Rene Discrates
2)Student will be asked to identify the coordinates of a given point with the help of board pin
3) Student will measure the perpendicular distance from y axis
3) Student will measure the perpendicular distance from x axis by pulling
4) Student will write the coordinates
5) Questions based on distance, mirror image, midpoint formula,mid point theorem,
making different figures joining the points with the help of thread
etc topics can be taught through the model		 Link VISHU GBSSS Baprola (1617258)
3. Secondary Distance Formula Proof of derivation of distance formula in two dimension using Pythagoras theorem Link Divya Ahlawat GGSSS Quresh Nagar (1208027)
4. Secondary Coordinate Geometry and its importance in real world. Students can easily find the coordinates of any point on Cartesian plane .
Also help students to find distance between two points .
Students correlate the use of distance formula and section formula in real world.		 Link Kanchan SKV Nehru Vihar (1207004)
5. Secondary Circle and Related Concepts Students will able to understand various concepts of circle in a very interesting and innovative way. Concepts of Radius, Diameter, Chord, Segment, Sector, Quadrant, Center Angle, Fraction, Tangent, Secant, Tangent from Outside point are equal, Angle at center is double of angle in same segment, angle in same segment are equal, angles in semi circle are 90. And many more come to exhibition and explore live. (It's a brief, पिक्चर अभी बाकी है...) Link JAI KANWAR S (Co-Ed)V Najafgarh (1822002)
6. Secondary Theorems related to circle Theorems related to circle Link Arvind kumar sharma GBSS Shahdara GT Road (1105013)
7. Secondary Coordinate Geometry Plotting and identification of a point, mirror and water image of a point, distance formula and some questions of section formula Link Neetu SBV Block-K Mangolpuri (1412002)
8. Secondary Division Of Polynomial A simple game for students to understand division of polynomials with remainder zero Link RACHNA DAGAR SKV Dhansa (1822039)
9. Secondary Algebra Tlm is used to teach different concept of Algebra by using algebra tiles such as
factorisation of polynomial ,solution of linear and quadratic equation ,		 Link Ranu kumar jain GBSSS Moti Bagh-I (1719010)
10. Secondary Similarity of Geometrical Figures ( ज्यामितीय आकृतियों की समरूपता) भुजाओं की समान संख्या वाले दो बहुभुज समरूप होते हैं, यदि- (i) उनके सभी संगत कोण बराबर हों तथा (ii) उनकी सभी संगत भुजाएं एक ही अनुपात (समानुपात) में हों। Link Shankar Choudhary AT SBV Chattarpur (1923081)
11. Secondary Probability This TLM on probability has been designed keeping in mind the diverse beauty of
our classroom flowers.It is simple and effective to use by an
individual or a group of individuals.It will help in learning basics of
probability through some hands-on activities and related concepts.
I believe every child will find it simple, aesthetic and easy to understand.		 Link SAPNA JANGRA SV Surhera (1822003)
12. Secondary Trigonometry Triumph This TLM enhances trigonometry learning by integrating visual aids, hands-on activities,
and real-life applications.
It helps students decode complex problems, build 3D models,
and connect classroom concepts to practical scenarios like measuring
heights with a clinometer. The Mini Challenge Zone fosters critical thinking and
problem-solving through creative and advanced-level challenges.
This approach makes trigonometry engaging, interactive,
and relevant to real-world problems.		 Link Manisha Kakkar SKV No. 1 Chand Nagar (1514011)
13. Secondary Probability I have made this TLM in 2 parts one to introduce probability and its
use in daily life and future prospects another to
discuss sample space for class X questions .		 Link Mani Khanna MBPBM SKV Shahdara GT Road (1105110)
14. Secondary Circle Ki Duniya Circle ki Duniya TLM motivates students to learn themselves by
doing practical and hands on activities. It also
promotes working in groups. This TLM focuses theorems related to
circle that are taught in classes ninth and tenth.
It would help students to regain their knowledge for longer duration.		 Link Nupur Mandal ASOSE DBRA Sector 18 Rohini (1310469)
15. Secondary Thales Theorem A working model to explain the concept of Thales theorem practically . Link Anjala Nijhawan GGSSS AP Block Shalimar Bagh (1309033)
16. Secondary Magical circle Box Basically Magical Circle Box demonstrate the theorems , basic terms and problem
solving approach of the Chapter whose name is TANGENT TO A CIRCLE
and also we demonstrate the theorems of circle of class 9 and basic
terminologies of circle 		Link Shivam Kumar GBSSS No. 1 Khanpur (1923020)
17. Secondary Circles and area related to circles In my TLM I explain theorems related to circles Link Sapna rani GGSSS Chattarpur (1923048)
18. Secondary Basic Proportionality Theorem (BPT) To explain BPT for any type of triangle to make the concept more clear. Link Pooja Kumari SKV No. 1, Gandhi Nagar (1003027)
19. Secondary Fun with polynomials It deals with division, multiplication, subtraction and addition of polynomials ,
addition and subtraction of algebraic expression.
to make things easier , only coefficient are dealt with.		 Link Manisha Aggarwal GGSSS Block-SU Pitampura (1411041)
