  10. 10. HOW TO DRAW A LINE SEGMENT TO DRAW A LINE SEGMENT OF 4 ½ CM STEP 1: mark a point on a blank sheet of paper STEP 2: keep the scale with the zero mark at the point. Hold the scale firmly with left hand. STEP 3: use the other hand to draw a line from the point along the edge of scale to the mark halfway between 4 cm and 5cm.
  11. 11. This line measures 4.5 cm 0 1 2 3 4 5 6
  12. 12. TO DRAW A LINE SEGMENT OF 5.7 cm STEP 1: SAME AS BEFORE STEP 2: SAME AS BEFORE 0 1 2 3 4 5 6 7 STEP 3: draw a line from 1 to 5,it will make 4 cm and then count small lines upto 7. this will make 4.7 cm
  13. 13. MEASURING DISTANCE 1 m = 100 cm THIS MEANS, 5 m = 500 cm 2 m = 200 cm 8 m = 800 cm 1m 80 cm = 100 cm + 80 cm = 180 cm
  14. 14. MORE EXAMPLES 6 m 45 cm = 600 cm + 45 cm = 645 cm 3 m 6 cm = 300 cm + 6 cm = 306 cm 9 m 9 cm = 900 cm + 9 cm = 909 cm
  15. 15. MEASURING MASS WE KNOW, 1000 g = 1 kg 1 kg = 500 g + 500 g 500 g= 250 g + 250 g it means, 1 kg = (250 g + 250 g)+(250 g +250 g ) = 4 x 250 g 1 kg = 10 x 100 g
  16. 16. SOME WEIGHTS WHICH ARE AVAILABLE IN MARKET 5 KG 2 KG 1 KG
  17. 17. FOR MEASURING LESS THAN 1 KG 500 g 200 g 100 g 50 g
  18. 18. MEASURING CAPACITY WE KNOW , 1000 ml = 1 litre 1 litre = 500 ml + 500 ml 500 ml = 250 ml + 250 ml So, 1 litre =(250 ml + 250 ml) +(250 ml + 250 ml)
  19. 19. WORD PROBLEMS If a person is allowed to carry 9 kg weight on aeroplane , then how much weight can 9 people can carry?
  20. 20. 9 kg 9 kg 9 kg 9 kg 9 kg 9 kg 9 kg 9 kg 9 kg
  21. 21. ANSWER TO QUESTION 1 PERSON CAN CARRY = 9 Kg 9 PERSON CAN CARRY = 9 Kg x 9 = 81 Kg 9 people can carry 81 kg of luggage
  22. 22. WORD PROBLEM 2 IF A LION IN A ZOO IS FED WITH 25 Kg OF MEAT , THEN HOW MANY LIONS CAN BE FED WITH 125 Kg OF MEAT?
  23. 23. 25 Kg 25 Kg 25 Kg 25 Kg 25 Kg 25 Kg
  24. 24. ANSWER TO QUESTION 1 LION IS FED = 25 kg Number of lions that can be fed with 125 kg of meat = 125 -:- 25 = 5 5 lions can be fed with 125 kg of meat.
  25. 25. Application in real life Que: Rakesh walked 470 m from his house to the market and back again . What distance did he walk in all? house M A R K E T 470 m 470 m

  29. 29. FINDING DOUBLE OF QUANTITY TO FIND DOUBLE OF A QUANTITY: EITHER MULTIPLY IT BY 2 OR ADD THE QUANTITY TWO TIMES
  30. 30. EXAMPLES WHAT IS THE DOUBLE OF:
  31. 31. 60 g 15 g 90 g 75 g 25 g 100 g 80 g 45 g 30 g DOUBLE QUANTITY
  32. 32. FINDING HALF OF GIVEN QUANTITY TO FIND THE HALF OF A QUANTITY , WE HAVE TO DIVIDE IT BY 2
  33. 33. DIVIDE INTO HALF
  34. 34. FIND HALF OF THE QUANTITY 60 g 14 g 90 g 500 g 250 g 100 g 80 g 40 g 30 g HALF QUANTITY
