S4 Speaking Project Around the globe History speaks of many who travelled the world even when communication was not as advanced as today. Famous explorers like Megasthenes and Ibn Batuta are remembered till date. We know of their travels from the travelogues that they wrote. They wrote about their voyages as well as the new countries that they visited. Today, when we read their works, we realise that there is always something new to discover and learn about different places on our planet. Let us see how well you know this world! Play a game of naming places. Let the teacher name a place of their choice. Instruct learners to name another place that starts with the last letter of the previous word. Ask each of them to speak on the place they name for a minute. Hints: • Where is the place located? • What is the climate like? • What kinds of plants and animals can you find there? • What language is spoken there? • What kind of cuisine will you find there? 12 1/7/2019 3:24:16 PM NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 14

Edward Lear was an illustrator, landscape painter, author and poet. Lear is still remembered for his ‘nonsense poetry’ for children, known as ‘limericks’ today. Before Lear’s writings, most literature written for children was filled with ‘common sense’ instruction. Edward Lear was a pioneer of short and funny poetic rhymes. For this reason, Edward Lear has become a truly evergreen author, fondly nicknamed as the ‘Father of Limericks’. 14 1/7/2019 3:24:16 PM NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 16

Edward Lear’s nonsense poems and drawings enabled a much- needed comic relief for the rigid society of Victorian England. Children were raised very strictly in the Victorian times, and their education excluded humour or laughter. Imagine the sheer delight that the children must have felt upon reading Lear’s works, in which the most ridiculous and absurd situations were presented as rhymes! Lear’s limericks are genuinely meaningless and lacks any punchline or purpose. Regardless of this, they were a desirable source of entertainment and escape from the repressive norms of the Victorian society. Despite being born and raised in England, Lear travelled abroad for most of his adult life. During his travels, he loved to draw animals and landscapes. He especially liked birds. Lear adored his friends and his dear cat named Sanreno. He eventually built the house of his dreams in Italy, where he passed away at the age of 75 in 1888.

Reading the Text Archimedes was a Greek scientist in the court of King Hiero II. He lived in Syracuse nearly 2000 years ago. The king of the land wanted to get a gold crown made. He gave some gold to a goldsmith to make a suitable crown. After a few days, the goldsmith brought the finished Archimedes crown to the king. The crown was weighed. The weight of the crown was equal to the gold given to the scientist goldsmith by the king. The king looked at the colour of the crown and something seemed odd. He had a suspicion. The goldsmith could have stolen some gold from the amount handed over to him. The king wanted to find out the truth. He said to Archimedes, ‘Find out if any gold has been stolen and how much.’ But how was Archimedes to do that? He thought about suspicion the problem day and night! One day, Archimedes was about to take his bath. He was busy thinking about the problem and did not notice that the bathtub was already full to the brim. As he slid into the bathtub, a large quantity of water flowed over the brim of the bathtub. He noticed this and suddenly realised that he had the answer to his problem. He jumped out of the bathtub, shouting ‘Eureka! Eureka!’ ‘Eureka’ in Greek means ‘I have found it’. brim Do you know that different metals of the same weight have different volumes? Objects, when put in water, displace water. The volume of the water displaced by the object is equal to the volume of the object. For example, an iron cube weighing a kilogram will displace some water. However, an aluminium cube of the same weight will displace more water than the iron cube. Using these theories, Archimedes worked out a plan to find out the purity of the gold in the crown. Archimedes took two bowls. He filled both the bowls with water to the brim. Then, he placed each bowl separately in the middle of a large vessel. He placed the crown in a bowl. Water overflowed and collected at the bottom of the outer vessel. Then, he took a cube of pure gold. This cube was equal in weight to the crown. He kept this gold cube in the middle of the second bowl. Again, water overflowed and got collected at The Story of the Golden Crown 17 NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 19 1/7/2019 3:24:16 PM

the bottom of the outer bowl. Archimedes then measured the quantities of water in these two outer vessels. He found out the difference between the two quantities. The crown had displaced more water, while the gold cube displaced less. However, since both the crown and the gold cube were of the same weight, they should have displaced the same amount of water. Therefore, it became clear that the crown had other metals mixed in it. These confessed metals took up more space in water than pure gold. Archimedes reported these findings to the king. The king demanded the truth from the goldsmith, who then confessed. He had stolen some gold. He had in fact added other metals as a replacement. Thus, due to Archimedes’ clever principle, the king could discover the truth. This principle became famous as the “Archimedes’ principle” and is studied even today! Let Us Discuss 1) What did the king ask the goldsmith to make? 2) What suspicion did the king have? 3) W hat words did Archimedes shout when he found the solution to the king’s problem? 4) W hen Archimedes conducted his experiment with the gold crown and the solid gold cube, what were the results?

R5 Reading Comprehension Passage 1 Read the passage and answer the questions given below. In the evening, the priest kept a light behind the curtain and stood there with his puppet. When he moved the puppet behind the curtain, it cast a dancing shadow on it that was clearly visible to the emperor on the other side. As the emperor sat in front of the curtain and watched the dancing shadow, he listened to the stories narrated by the priest. The stories were about the queen. They were simply wonderful and brought back many of the emperor’s wonderful memories. The emperor clapped his hands with joy and said, ‘I would like to watch the puppet show every evening. I am delighted.’ Every day, the emperor attended court, talked to his ministers and courtiers and then watched the puppet show in the evening. He started taking great interest in his people. He built schools and hospitals in the name of the departed queen. He felt very happy when crowds of people gathered around him and praised him wherever he went. They would cheerfully shout, ‘Hail the Emperor! Hail the mighty one!’ The priest spoke to him one day, ‘Your Majesty, joys and sorrows are part of life. Whenever a person faces sorrow, they should always think of the good things and happy moments in life. They act as a source of joy that drives away all the sadness and cheers one up. They teach us to live happily and do good deeds. We can try to make others happy while remembering those who are no longer with us.’ The emperor smiled and nodded. ‘I thank you for guiding me and for such wise words’, he said. 32 1/7/2019 3:24:18 PM NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 34

Passage 2 Read the passage and answer the questions given below. A bird came down the walk, He did not know I saw. He bit an Angleworm in halves, And ate the fellow, raw. And then he drank a dew, From a convenient grass. And then hopped sidewise to the wall, To let a beetle pass. He glanced with rapid eyes, That hurried all around. They looked like frightened beads, I thought, He stirred his velvet head. Like one in danger, cautious, I offered him a crumb. And he unrolled his feathers, And rowed him softer home. Than oars divide the ocean, Too silver for a seam. Or butterflies, off banks of noon, Leap, plash-less as they swim. – Emily Dickinson 1) Why did the bird hop sidewise to the wall?

Concept 11.1: Like and Unlike Decimals Think The teacher asked Pooja to represent the fraction of girls, if there are 556 girls in a school of 1000 students. Pooja said: “The fraction of girls is 556 ”. 1000 The teacher asked her to represent the same in the decimal form. Do you know how to represent a fraction in its decimal form? Recall In class 4, we have learnt decimals and fractions with their conversions. Let us recall them. 1 1/7/2019 3:24:18 PM NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 42

Conversion of fractions into decimals To write the given fractions as decimals, follow these steps. Step 1: Write the whole part as it is. Step 2: Place a decimal point to its right. Step 3: Write the numerator of the proper fraction part. Conversion of decimals into fractions To convert a decimal into a fraction, follow these steps. Step 1: Write the number without the decimal point. Step 2: Count the number of decimal places (that is, the number of places to the right of the decimal number). Step 3: Write the denominator with 1 followed by as many zeroes as the number of digits after the decimal point. We observe that when a decimal number is converted into a fraction, the denominator is: • 10 if there is one digit after the decimal point. • 100 if there are two digits after the decimal point. & Remembering and Understanding We know that the first place to the right of the decimal point is called the tenths. The place to the right of the tenths is the hundredths. The place value of a number increases by ten when we move from right to left and decreases by ten when we move from left to right. Consider the following example. Example 1: Convert 1396 m into km. Solution: 1m= 1 km 1000 1396 Thus, 1396 m = 1000 km To represent 1396 km in decimal form, we get a new place value to the right 1000 of the decimal point. We get the first place after the decimal point by dividing the number by 10. It is called the tenths place. We get the second place after the decimal point by dividing the number by Decimals - I 2 NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 43 1/7/2019 3:24:18 PM

100. It is called the hundredths place. Similarly, we get the third place after the decimal point by dividing the number by 1000. It is called the thousandths place. 1396 Hence, 1000 km is written as 1.396 km in the decimal form. It is read as one point three nine six kilometres. Similar to the place value chart for numbers, we have a place value chart for decimals too.

unlike decimals. Decimal places: The digits in the decimal part are called decimal places. For example, 4109.34 has two decimal places; 1183.6 has only one decimal place. Equivalent decimals: The decimal numbers which have equal values are called equivalent decimals. For example, 0.3, 0.30, 0.300 are equivalent decimals. Like decimals: The decimal numbers that have the same number of decimal places are called like decimals. For example, a) 2.81, 35.94, 7.32, 145.67, 214.07 and b) 0.362, 51.093, 22.678, 8091.221, 1.003 are sets of like decimals. Unlike decimals: The decimal numbers that have different number of decimal places are called unlike decimals. For example, a) 5.11, 89.018, 3.4, 671.92 and b) 59.009, 231.8, 9.05, 12.25 are sets of unlike decimals. Convert unlike decimals to like decimals Consider a pair of unlike decimals, say 5.36 and 27.2. To find their equivalent decimals with the same number of decimal places, add as many 0s to the right of the decimal as needed. The equivalent decimal of 27.2 with two decimal places = 27.20 Thus, 5.36 and 27.20 are like decimals with two decimal places. Example 5: Convert the given unlike decimals into like decimals. a) 42.7, 53.28, 261.135, 11.01 b) 0.742, 12.06, 8.5, 17.12 c) 7.23, 2.1, 0.6, 4.382 Solution: a) Unlike decimals: 42.7,53.28, 261.135, 11.01 In these decimal numbers, the third decimal number has the highest number of decimal places = 3 5 1/7/2019 3:24:18 PM NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 46

S o, we have to find the equivalent decimals of the other three decimal numbers such that they have three decimal places. Thus, the required like decimals are: 42.700, 53.280, 261.135, 11.010 b) Unlike decimals: 0.742, 12.06, 8.5, 17.12 Like decimals: 0.742, 12.060, 8.500, 17.120 c) Unlike decimals: 7.23, 2.1, 0.6, 4.382 Like decimals: 7.230, 2.100, 0.600, 4.382 Application Let us see some real-life examples based on decimals. Example 6: If 502 out of 1000 students in a school are girls, then write the decimal equivalent of the fraction of girls in the school. Solution: The total number of students in the school = 1000 Number of girls = 502 The fraction of girls = 502 1000 The required decimal equivalent = 0.502 Example 7: If there is 263 cm of tape on a tape roll, how many metres of tape is on the roll? Give your answer in the decimal form. Solution: The length of the tape on the tape roll = 263 cm Converting into metres = 263 m 100 The required decimal form of the length of the tape = 2.63 m Example 8: The weight of a sugar jar is 5670 g. What is its weight in kilograms? Solution: The weight of a sugar jar = 5670 g Converting into kg = 5670 kg 1000 The required decimal form of the weight of the jar = 5.67 kg Decimals - I 6 NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 47 1/7/2019 3:24:18 PM

Concept 11.2: Compare and Order Decimals Think Pooja went to purchase a bag to gift her mother on her birthday. She selected two bags of prices ` 455.80 and ` 455.40. She couldn’t understand which is more expensive of the two. Do you know which is more expensive of the two? Recall We have already learnt about equivalent, like and unlike decimals. To compare two decimals, we should know the concepts of equivalent decimals and like decimals. Let us recall the concepts by answering the following: a) Write four equivalent decimals of 6.1. b) Convert these unlike decimals to like decimals: 32.5, 410.635, 6, 78.7 c) Identify the pair of like decimals: a) 39.12, 56.03 b) 0.14, 0.04 c) 6.75, 83.16 d) 7.101, 6.2 & Remembering and Understanding We know that, 1) Adding any number of 0s to the right side of the decimal point does not change its value. 2) U nlike decimals can be converted to like decimals by adding zeros at the right end. Now, let us learn to compare two decimals through a few examples.

Solution: a) 69.2 and 69.02 Step 1: T o compare two decimals, follow these steps: Step 2: C onvert the given decimal numbers into like decimals. Step 3: 69.20, 69.02 C ompare their integral parts. The decimal with the greater integral part is greater. Here, 69 = 69 If the integral parts are the same, then we have to compare the tenths digits. The decimal with the greater digit in the tenths place is greater. If the tenths digits are the same, compare the hundredths digits and so on. 69.20 69.02 6=6 9=9 2>0 Hence, 69.20 > 69.02 Note: Always start comparing from the largest place value in the integral part. b) 77.10 and 77.012 Step 1: nConvert the unlike decimals into like decimals: 77.100, 77.012 Step 2: Compare the integral parts: 77 = 77 Step 3: Compare the tenths digits: 1 > 0 Hence, 77.10 > 77.012. c) 3.5631 and 3.61 Step 1: Convert the unlike decimals into like decimals: 3.5631, 3.6100 Step 2: Compare their integral parts: 3 = 3 Step 3: Compare the tenths digits: 5 < 6 So, 3.5631 < 3.61000. Example 11: Which is smaller between each of the given pairs of decimal numbers? a) 367.80 and 362.801 b) 21.673 and 21.673 c) 11.729 and 11.726 9 1/7/2019 3:24:19 PM NR_BGM_9789386663511 MAPLE G05 INTEGRATED TEXTBOOK TERM 3_Text.pdf 50
