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.

This line measures 4.5 cm

0 1 2 3 4 5 6

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

MEASURING DISTANCE

1 m = 100 cmTHIS MEANS,

5 m = 500 cm2 m = 200 cm8 m = 800 cm

1m 80 cm = 100 cm + 80 cm= 180 cm

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

MEASURING MASS

• WE KNOW,1000 g = 1 kg1 kg = 500 g + 500 g500 g= 250 g + 250 g

it means,1 kg = (250 g + 250 g)+(250 g +250 g )

= 4 x 250 g1 kg = 10 x 100 g

SOME WEIGHTS WHICH ARE AVAILABLE IN MARKET

5 KG 2 KG

1 KG

FOR MEASURING LESS THAN 1 KG

500 g 200 g

100 g50 g

MEASURING CAPACITY

• WE KNOW , 1000 ml = 1 litre1 litre = 500 ml + 500 ml500 ml = 250 ml + 250 mlSo,1 litre =(250 ml + 250 ml) +(250 ml + 250

ml)

WORD PROBLEMS

• If a person is allowed to carry 9 kg weight on aeroplane , then how much weight can 9 people can carry?

9 kg9 kg 9 kg 9 kg

9 kg9 kg9 kg9 kg

9 kg

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

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?

25 Kg25 Kg 25 Kg

25 Kg 25 Kg 25 Kg

ANSWER TO QUESTION

1 LION IS FED = 25 kgNumber of lions that can be fed with 125 kg

of meat = 125 -:- 25= 5

5 lions can be fed with 125 kg of meat.
