Chapter Measurements 9 Let Us Learn About • m easuring lengths and distances using standard units. • comparing weights of two or more objects. • using simple balance to compare weights. • o rdering containers based on their capacities. Concept 9.1: Measure Lengths Using Standard Units Think David’s mother bought 3 cubits of garland. David observed that the same garland measured 5 cubits with his cubit. He wondered how he got more cubits than his mother. Do you know the reason for the difference? Recall Remember that the length of an object is the distance between its two ends. We can measure the lengths of long objects using some shorter objects. Also, we can measure objects using our hands, palm, foot and so on. NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 23 1 1/8/2019 9:22:24 AM
hand span cubit foot pace For example, consider the following: a) 9 paper clips long b) 5 erasers long c) 12 hand spans long d) 4 crayons long & Remembering and Understanding When different people measure an object using their body parts, they all get different lengths. The measures are different because the length of the body part is different for different people. 2 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 24
So, measures such as hand span, cubit, foot, leg span are called non-standard units. The standard unit of measurement of length is called metre. It is used to measure the length of a room, width of a room, height of a building and so on. We also use metre to measure the amount of cloth needed to make a dress. The unit ‘metre’ is written in short as ‘m’. To measure lengths smaller than a metre, we use another unit called the centimetre. Centimetre is used to measure a line, length of a ribbon and so on. We write ‘centimetre’ in short as ‘cm’. To measure lengths larger than a metre we use a larger unit called the ‘kilometre’. It is written in short as ‘km’. It is used to measure the length of a road, the distance between two places, lengths of bridges, tunnels and so on. Thus, 1 km > 1 m > 1 cm Using these standard units, we can measure the lengths of objects accurately. Standard units give the same measure of the object anywhere in the world. The standard instruments used to measure length are a ruler (or a scale), a measuring tape and so on. A ruler is used to measure the length in centimetres and inches. A measuring tape is used to measure longer lengths in metres and kilometres. Measuring objects using a ruler A ruler is made of plastic or metal. It has two scales on both sides as shown below. On one side, there is a centimetre scale and on the other side is the inch scale. We measure lengths of small objects such as a chalk, duster, sketch pen, pencil, pencil box and so on using any of these scales. The distance between 0 and the number at the other end of the object on a ruler is the length of the object.

To measure the length of an object using a ruler, follow these steps: Step 1: Keep one end of the object at the zero of the ruler. Step 2: Note the number on the ruler which is at the other end of the object. Step 3: Write the units beside the number noted in step 2. The number along with the unit denotes the length of the object. Observe the following: a) The distance between the two ends of the pencil is 6 cm. So, the pencil is 6 cm long. Similarly, b) The water bottle is 12 cm long. c) The cell phone is 9 cm long. 4 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 26
Let us consider a few examples. Example 1: Measure these objects and write their lengths with the correct unit. One is done for you.

Application We measure longer objects in metres and distances in kilometres. Let us now learn how these units are related. On the centimetre ruler, we see that the distance between any two consecutive numbers is 1 cm. We see 10 equal divisions in a centimetre. Each of these divisions is called a ‘millimetre’, written in short as ‘mm’. Example 3: Tick the unit used to measure the lengths of the following. One is done for you. Object cm Units km Blue whale m Book Toothbrush Table Road 6 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 28
Example 4: Tick the unit used to measure the following. One is done for you. Object Units mm cm m km Window Ribbon Rope Cloth Higher Order Thinking Skills (H.O.T.S.) Let us see an example involving standard and non-standard units. Example 5: The length of Shyam’s hand span is 8 centimetres. He measured the length of a table as 5 hand spans. What is the length of the table in centimetres? Solution: The length of Shyam’s hand span = 8 centimetres The length of the table = 5 hand spans The length of the table in centimetres = 5 × 8 centimetres = 40 centimetres So, the table is 40 cm long.

Concept 9.2: Compare Objects Using a Simple Balance Think David’s mother bought some flowers. She found that the flowers were lighter than what she had asked for. David’s mother weighted the flowers using a simple balance and found that she was right. Why was there a difference? Recall We have learnt how to guess the heaviness of objects based on their size. Let us answer the following to recall heavy and light objects. Write heavier or lighter in the blanks. One is done for you. 3 balls are heavier than 1 ball. The cabbage is __________ than the potato. 8 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 30
2 lotuses are _____________ than 2 The capsicum is ______________ than roses. the pumpkin. & Remembering and Understanding The standard instrument used to measure the weight of an object is the simple balance. The standard units of weight are gram and kilogram. We write grams as g and kilograms as kg. A smaller unit of weight is milligram written as mg. For example, tablets, spices and so on are measured using milligrams. Heavier objects such as pencils, cereals and so on are measured using grams. Objects heavier than the ones given above need a greater unit of measurement. We use kilograms to measure such objects. Dal, rice, sugar, wheat and so on are measured in kilograms. Weights of objects such as watermelon, human beings and books are measured in kilograms. MMeualstuiprelicmaetinotns 9 NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 31 1/8/2019 9:22:25 AM
5 kg 6 kg 1 kg Thus, 1 kg > 1 g > 1 mg Example 6: Tick the unit used to measure the following. One has been done for you. Objects mg g kg a) b) c) 1/8/2019 9:22:25 AM d) e) 10 NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 32
Application Jewellers use grams to weigh ornaments. 10 g of jewellery is called a ‘tola’. Let us see an example where we need to use standard units of weights. Example 7: Write the unit that must be used to measure the weights of the following objects. One is done for you. g Higher Order Thinking Skills (H.O.T.S.) We can weigh objects using a simple balance and the weights. To weigh an object, we place it on the left pan of the balance and add the weights on the right pan. When both pans are at the same level, we say that the beam is balanced. We then read the total weights put on the pan. This gives the weight of the object. From the given figure, we see that the weight of the watermelon is 5 kg. MMeualstuiprelicmaetinotns 11 NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 33 1/8/2019 9:22:25 AM
Example 8 : Observe the figures and write the weights of the given objects. One is done for you. a) 1 kg + 1 kg + 1 kg = 3 kg b) The pumpkin weighs The dog weighs 3 kg . __________kg. Concept 9.3: Compare Containers for Capacities Think David saw glasses of different sizes in his kitchen. He wondered why so many types of glasses were needed. He also observed that the glasses he used to drink water and milk were different. Why do you think we use containers of different sizes? Recall Recall that we use vessels and containers of different sizes. A tub can hold more water than a bucket. Similarly, a bucket can hold more water than a jug. The capacity or volume of a container is the quantity of water or any other liquid that it can hold. There are different types of vessels based on their capacities. Glasses, bottles, jugs and so on are non-standard units to measure liquids. 12 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 34
Observe these containers and order them based on their capacity. Write 1 for the smallest container. 9.3 I Remember and Understand The standard units of capacity are millilitres, litres and kilolitres. The following figure shows different containers used for measuring capacity: Small quantities of liquids such as tonic doses are measured in millilitres, written as ‘mℓ’. Quantities of oil, milk, fruit juices and so on are measured in litres, written as ‘ℓ’. Larger quantities such as petrol in tankers are measured in kilolitres, written as ‘kℓ’. Thus, 1 kℓ > 1 ℓ > 1 mℓ MMeualstuiprelicmaetinotns 13 NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 35 1/8/2019 9:22:25 AM
Example 9: Tick the units used to measure the following. One has been done for you. Container Units ℓ mℓ 14 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 36
Example 10: Circle the vessel which uses the given unit of capacity. One is done for you. Unit of Vessels capacity ℓ mℓ ℓ Application Let us see some real-life examples involving measurement of capacities. Example 11: Renu has 38 litres of orange juice in a bucket. A jug that can hold 2 litres is used five times to fill the juice glasses. How much juice is remaining in the bucket? Solution: Quantity of orange juice in the bucket = 38 ℓ Quantity of orange juice a jug can hold = 2 ℓ MMeualstuiprelicmaetinotns 15 NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 37 1/8/2019 9:22:25 AM
The jug was used 5 times. So, the quantity of the orange juice poured in the juice glasses is 2 ℓ × 5 = 10 ℓ Quantity of the orange juice remaining in the bucket is (38 – 10) litres = 28 litres So, 28 litres of orange juice is remaining in the bucket. Example 12: Milk from two full jugs each measuring 55 litres is poured into a bucket of 200 litres. How many more litres of milk can the bucket hold? Solution: Capacity of the bucket = 200 litres Quantity of milk poured into the bucket = 55 litres + 55 litres = 110 litres Difference in capacities = (200 – 110) litres = 90 litres So, the bucket can hold 90 more litres of milk. Higher Order Thinking Skills (H.O.T.S.) Let us now see how we use standard units of volumes in a few real-life situations. Example 13: Sravan pours 6 glasses of juice into a jug. If each glass measures 250 mℓ, how much juice is in the jug? Solution: Number of glasses of juice poured in the jug = 6 Quantity of juice in each glass = 250 mℓ Total quantity of juice in the jug = 250 mℓ + 250 mℓ + 250 mℓ + 250 mℓ + 250 mℓ + 250 mℓ = 1500 mℓ So, the quantity of juice in the jar is 1500 mℓ. 16 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 38

Making a list of items may take a lot of time if there are many items. Hence, it is necessary to use a pictograph. Pictograph: Listing the different data items using picture symbols is called a pictograph. To read a pictograph, we: a) look at the given key. b) multiply the given number of pictures with the value of the key. Key: A key on a pictograph tells us how many objects each picture stands for. Consider these examples. Example 1: If = 10 strawberries, then means how many strawberries? Solution: = 10 strawberries (Given). So, = 3 × 10 strawberries = 30 strawberries 22 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 44
Example 2: If = 4 cupcakes, then means how many cupcakes? Solution: = 4 cupcakes (Given) So, = 2 × 4 cupcakes = 8 cupcakes Example 3: The number of cakes baked in a week is given in a pictograph. Observe the given pictograph and answer the questions. Key: = 5 cakes Day of the week Number of cakes baked in the week Sunday Monday Tuesday Wednesday Thursday Friday Saturday DMautaltiHpalicnadtlinogn 23 NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 45 1/8/2019 9:22:25 AM
a) How many cakes were baked on Thursday? b) On which day were the highest number of cakes baked? c) On which day were the least number of cakes baked? d) How many cakes were baked on Wednesday? Solution: a) Number of cakes baked on Thursday = 1 =1 × 5 cakes = 5 cakes b) The highest number of symbols given is for Sunday. So, the highest number of cakes were baked on Sunday. c) T he least number of symbols given is for Thursday. So, the least number of cakes were baked on Thursday. d) The number of symbols given for Wednesday is 3. S o, the number of cakes baked on Wednesday is 3 × 5 cakes = 15 cakes. Application Let us learn more about pictographs through these examples. Example 4: The number of students in a class having pets is given in the pictograph. Understand it and answer the questions. Key: 1 = 4 students, 1 = 2 students 24 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 46
Pet Number of students a) How many students are present in the class? b) How many students have a pet dog? c) How many students have a pet cat? d) Which pet does the maximum number of students have? e) Which pet does the minimum number of students have? Solution: a) 1 = 4 students So, 10 = 4 × 10 students = 40 students DMautaltiHpalicnadtlinogn 25 NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 47 1/8/2019 9:22:25 AM
= 2 students So, 3 = 6 students S o, the total number of students present in the class = 40 + 6 = 46 students. b) 1 = 4 students So, 3 = 3 × 4 students = 12 students 1 = 2 students So, number of students who have a pet dog = 12 + 2 = 14. c) 1 = 4 students So, 2 = 2 × 4 students = 8 students 1 = 2 students So, the number of students who have a pet cat = 8 + 2 = 10. d) T he maximum number of symbols is given for the dog. So, most of the students have dogs as pets. e) T he minimum number of symbols is given for the fish. So,the least number of students have fish as pets. Example 5: The given pictograph shows the grades that students of Class 2 got in an exam. Read the pictograph and complete the table. Key: = 2 students; = 1 student A+: Excellent, A: Very Good, B+: Good B: Fair, C: Better, D: Satisfactory, F: Fail 26 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 48

Higher Order Thinking Skills (H.O.T.S.) We have learnt how to read a pictograph. Now, let us learn to draw a pictograph when some data is given. Example 6: The number of flower pots sold in a nursery on one day are 12 Marigold, 21 Jasmine, 9 Tulip, 6 Daisy and 6 Lily. Represent the data in a pictograph taking a symbol equal to three flower pots. Then answer the questions that follow. a) Which flower pots were sold the maximum? b) Which flower pots were sold in equal number? c) How many tulip flower pots were sold? Solution: = 3 flower pots Flower pots sold on a day Marigold Jasmine Tulip Daisy Lily a) Jasmine flower pots were sold the maximum. b) Daisy and lily flower pots were sold in equal number. c) = 3 flower pots = 3 × 3 = 9 flower pots. So, 9 tulip flower pots were sold. 28 1/8/2019 9:22:25 AM NR_BGM_9789386663092 MAPLE G02 INTEGRATED TEXTBOOK TERM 3_Text.pdf 50
