Reinforcing that concepts of division, multiplication and tables are inter related. Learning to develop tables without rote learning everything. Division of objects into equal numbers and different methods of divisionhttp://www.youtube.com/watch?v=GdgCCxkuJuc&list=PL878190747F2AA508
Concept of weight and assessment of weight of various things from everyday life like a pencil box, sack of wheat, school bag etc. Making of a weigh scale also shown. Comparision of weight of different things and concept of how weight of many small things would add upto the weight of a big thing http://www.youtube.com/watch?v=8qd14H7jiwA&list=PL878190747F2AA508
Concept of perimetre is introduced by using the term ‘length of the boundary’. Perimetre of various things like leaf, book etc. are measured using a rope http://www.youtube.com/watch?v=rQ1d_lFk0R4&list=PL878190747F2AA508
Data handling and representing data through pie diagram, bar charts, chappathi charts etc.http://www.youtube.com/watch?v=-v0W5UdbjQI&list=PL878190747F2AA508

Class-5

Revision of various concepts learnt upto 4th including shapes, estimation, simple operations, sense of large numbers,money, loans etc.through real life situations involving fish market http://www.youtube.com/watch?v=FvetzSfwN_U&list=PL314D2B8F59F86B8B
Angles http://www.youtube.com/watch?v=YLGgLRwwchE&list=PL314D2B8F59F86B8B
Develops a sense towards the concept of ‘area’ through real life examples. Different things are compared in terms of area and characters guess as to which is bigger. Also the concept that perimeter of 2 shapes can be different, but their area can be the same http://www.youtube.com/watch?v=HLp8QweICWc&list=PL314D2B8F59F86B8B
Talks of parts and wholes;. Various real life activities are played out to help children develop a conceptual understanding about fractions. Equivalent fractions like 1/2 = 2/4 = 3/6 = 4/8 etc. is introduced.http://www.youtube.com/watch?v=by1hgx5o7uY&list=PL314D2B8F59F86B8B
Mirror Images http://www.youtube.com/watch?v=0ymsPrKGIu8&list=PL314D2B8F59F86B8B
Introduction of the concept of ‘multiples’. It explains as to how when a bigger number is wholly divisible by another smaller number, it becomes the multiple of that smaller number. http://www.youtube.com/watch?v=24M8ErqJg3s&list=PL314D2B8F59F86B8B

Chapter focuses on visualisation of 3 dimensional shapes and how they can be represented on paper through 2 dimensions. Examples like flattened boxes, layout plans of rooms and perspective drawings are given to enable better understanding of the concept. http://www.youtube.com/watch?v=ku7wHOm8Vww&list=PL314D2B8F59F86B8B
Concept of ‘tenths and hundredths’ like 1/10th of a cm = 1 mm. introduction of decimals and money with decimal points. Explains things like 1/100 = 0.01, 2/10 = 0.2 etc. Concept of measuring temperature in ‘celsius’ unit is also introduced.http://www.youtube.com/watch?v=nOMV5NC7kxQ&list=PL314D2B8F59F86B8B
Concept of ‘area and its boundary’ and expressing area in square cm. Reinforcing the fact that perimetre of two objects/shapes can be different but area can be the same. Finding out the area of a square or rectangle, when perimeter and length of even one side is known. http://www.youtube.com/watch?v=fK79gAAkiqA&list=PL314D2B8F59F86B8B
Reinforcement of concepts of perimetre and area. Understanding the difference between sq cm, sq m and sq km. Calculating perimetre, area of different shapes. http://www.youtube.com/watch?v=DVth4eAkKHM&list=PL314D2B8F59F86B8B
Data handling and the usage of ‘tally marks’ to record data of a variety of things with larger numbers. Sense of approximation is also introduced through activities. Comparision of temperatures between different places. Drawing of growth chart and family tree is also explained http://www.youtube.com/watch?v=ywbAFANF0nY&list=PL314D2B8F59F86B8B
Multiplication ( conversions) http://www.youtube.com/watch?v=rpMXG5z5KXE&list=PL314D2B8F59F86B8B
Measurement – volume http://www.youtube.com/watch?v=XoiyHm2rjBM&list=PL314D2B8F59F86B8B
Volume of different shapes using cm cubes. Explanation as to how length x breadth x height = volume. An activity of cube making is undertaken to better explain the concept. Easily available things like matchboxes are used to help children understand this concept. http://www.youtube.com/watch?v=4aZw_1S0168&list=PL314D2B8F59F86B8B
