TLM Middle 2024

S.No. Class Title of TLM Brief Description Video of TLM Explanation by self or using it with Students Prepared By
1. Middle INTEDO Addition of integers by game Link K.R.Renuka Devi GGSS Phase-III Mayur Vihar (1002199)
2. Middle Linear Equations in one variable To create interest of the students and to grab their attention colourful
small toys are used in the TLM for basics of linear Equations in one
variable like constants, variables, LHS, RHS. Solution of Equations
is explained with the help of a balance, as they are familiar with
the rules that when equals are added or subtracted
from equals results are equal. Simple Equations involving negative numbers
are solved using coins and cut outs.		 Link MEENAKSHI BANGIA GGSSS No. 1 Tilak Nagar (1514014)
3. Middle HCF and LCM Objective:To find HCF and LCM
Material required:Card board,chart paper,stones.ice cream cups etc
Method:first we find factors and multiples .
1. We take a number and take cut outs of that number and make the groups of that cut outs .
If groups made then that number is the factor of that number
2.For calculating HCF we put stone in the factor of one number and then other numbers.
Where two stones exits then it is common factor and highest common factor is HCF
3.For LCM we put stone in the multiple of both the numbers where two stones exits
then that number is common multiple and the least common multiple is LCM		 Link Yogita Saini GSCo-Ed SSS Sector-6 R K Puram (1719070)
4. Middle Linear equation in one variable 1.This TLM is used to solve algebraic equations in one variable.
2.This is made so that hearing impaired students and visually impaired students can also learn.
3. Equations are written in brail.
4. Tiles are made through clay so this is eco-friendly.
5. Low cost materials are used.		 Link Neeraj SBV Railway Colony Tuglakabad (1925017)
5. Middle Geometrical Gems This TLM deals with the concept of lines,different types of
angles,triangles and their properties, angle sum Property of triangle
,quadrilateral and types of quadrilaterals, polygons and sum of angles of a polygon. 		Link SONIA SETIA GGSSS No.2 Uttam Nagar (1618021)
6. Middle Understanding lines and Angles All geometric concept from 6 to 10 Link Shweta Gupta GBSSS No-2 Avantika Sector-1 Rohini (1413019)
7. Middle MATHS GYM Maths gym is about simple topics about middle class ie Roman numbers,ascending and descending numbers,
Greater than and Less than concepts,Number line ,Angles on protactor .
Students can learn these concepts easily with the help of activity learning.		 Link MAMTA PUNYANE AAA. G. Skv Tkd Ext. (1925061)
8. Middle Introduction to HCF and LCM Learning how to calculate HCF and LCM Link Swati Mittal Co-Ed SSS Block ZP Pitampura (1411007)
9. Middle Symmetry This TLM covers all the concepts of symmetry such as symmetry in nature, line of symmetry,
symmetry of geometrical shapes, rotational symmetry, symmetry of alphabets
and some real life examples of rotational symmetry. 		Link Monika Yadav RPSKV Rithala (1413026)
10. Middle Factorisation Of Quadratic Polynomial. CLASS: VIII TOPIC: FACTORISATION
SUBTOPIC: Factorisation Of Quadratic Polynomial
OBJECTIVE:
To find the factors of a quadratic polynomial by geometrical representation.
Materials Required:
(i) Coloured  paper
ii) Coloured sketch pen
iii) a pair of scissors
iv)Fevicol
v) Geometry box
vi)Cardboard sheet
vii)Chart paper
Steps/Procedure
(i) Every x² represents the area of green square of side xunits.
(ii) Every x represents the area of pink rectangle of dimension(1×x).
(iii) All positive integers are represented by pink squares of dimension (1×1).
(iv) Lets find the factors of x²+5x+6.
To represent x² ,take one green square.To represent 5x , take 5 pink rectangular pieces.To represent 6, take 6 pink square
pieces.Now arrange all the pieces in the form of a square/rectangle. Result
The dimensions of the resulting square/rectangle are the two factors of the quadratic expression.
x²+5x+6=(x+3)(x+2)		 Link Arushi Lingwal GGSSS Sonia Vihar (1104335)
11. Middle Quadrilateral Exterior and interior angles of quadrilateral Link Sushma sharad
12. Middle Circle and its applications TLM contains all the parts of circle and applications. Link Vikas hooda SBV Pkt-2 Sect A-6 Narela (1310430)
13. Middle Strongest polygon on earth Strongest polygon on Earth is triangle.It is the most basic shape but it is also the strongest one.
They are combined to form larger structures like truss bridge,cell phone towers
and aircraft wings.Triangles are strong because they are rigid and does not have diagonals.		 Link Taranjeet Kaur SKV No.2 Tagore Garden (1515025)
14. Middle Lines and angles With the help of my TLM we can understand easily diffrent type of lines and angles
like parallel line , intersecting line and corresponding angles etc. 		Link Kiran Devi SKV Old Seelampur (1003204)
