Th H T O Solve these Th H T O Th H T O 2568 1259 ×8 5689 ×4 ×2 Properties of Multiplication Identity Property: For any number ‘a’, a × 1 = 1 × a = a. 1 is called the multiplicative identity. For example, 461 × 1 = 1 × 461 = 461. Zero Property: For any number ‘a’, a × 0 = 0 × a = 0. For example, 568 × 0 = 0 × 568 = 0. Commutative Property: If ‘a’ and ‘b’ are any two numbers, then a × b = b × a. For example, 12 × 3 = 36 = 3 × 12. Associative Property: If ‘a’, ‘b’ and ‘c’ are any three numbers, then a × (b × c) = (a × b) × c. For example, 3 × (4 × 5) (3 × 4) × 5 3 × 20 12 × 5 60 60 (3 × 4) × 5 = 3 × (4 × 5) Distributive Property: 1) If 'a', 'b' and 'c' are any three numbers, then: a × (b + c) = (a × b) + (a × c). For example, 2 × (3 + 5) = (2 × 3) + (2 × 5). 2 × 8 = 6 + 10 16 = 16 Multiplication distributes over addition.

R3 Reading Comprehension Passage 1 Read the story and answer the questions given below. Last Sunday, little Phulmani went to see a jatra with her parents. She was very excited to see the jatra. The next day, when she told the story of the performance to the class, her teacher said that jatra is actually a kind of folk theatre. This kind of theatre is performed under different names in different parts of our country. It is called ‘tamasha’ in Maharashtra, ‘nautanki’ in northern India and ‘jatra’ in Bengal. Most of these folk theatres are based on incidents or characters from myths. India has a rich heritage of classical dance forms, and many of them are based on myths. The dancers wear colourful costumes and dance in rhythm with music. Kathak is a dance of northern India, while Bharatanatyam, Mohiniattyam, Kuchipudi and Kathakali are all from southern India. Manipuri and Odissi are dance forms of eastern India. Such a wide variety of dance forms cannot be found anywhere else in the world. Phulmani came to know that Indian kings and rulers patronised classical music and dance in their courts. Emperor Akbar loved to listen to the songs of Tansen. Our country is so big that we have many different styles of classical music like Hindustani and Carnatic. Many of these styles began in temples and developed down the ages.

Passage 2 Read the story and answer the questions given below. Welcome to the Arctic! That is the cold, windy area around the North Pole. It includes the Arctic Ocean and the land near it. Snow and ice cover the ground for most of the year. The walrus, polar bear and snowy owl are a few animals that live in this habitat and survive the cold. A walrus spends most of its time in icy water. It has a thick layer of blubber, or fat, under its skin to keep it warm. When a walrus swims, blood flows away from its skin to important organs inside its body. That keeps heat from leaving the walrus’s body, and its skin turns white. When it is warm again, its skin turns pink. A polar bear has special fur to keep it warm. Each hair is walrus shaped like a straw. The shape helps direct sunlight towards the bear’s black skin, which collects and holds in heat. Polar bears also have a layer of blubber under their skin. A snowy owl has two layers of feathers that cover its entire body. The bottom layer, which is soft and fluffy, is called ‘down’. The outer layer of feathers is thick. In strong wind, the snowy owl may hide on the ground behind a pile of snow or rocks to block the wind. polar bear 1) Which are the animals that live in the Arctic?

Chapter Division 7 Let Us Learn About • dividing 4-digit numbers by 1-digit and 2-digit numbers. • dividing 3-digit numbers by 2-digit numbers. • properties of division. Concept 7.1: Divide Large Numbers Think Jasleen and seven of her friends want to share 3540 papers equally among themselves. Do you think the papers can be divided, without some being left over? Recall Recall that we can write two multiplication facts for a division fact. For example, a multiplication fact for 45 ÷ 9 = 5 can be written as 9 × 5 = 45 or 5 × 9 = 45. 45 ÷ 9 = 5 ↓ ↓ ↓ Dividend Divisor Quotient The number that is divided is called the dividend. The number that divides is called the divisor. The number of times the divisor divides the dividend is called the quotient.

Factors Factors Multiplicand × Multiplier = Product Multiplicand × Multiplier = Product 5 × 9 = 45 9 × 5 = 45 ↓ ↓ ↓ ↓ ↓ ↓ Divisor Quotient Dividend Divisor Quotient Dividend The part of the dividend that remains without being divided is called the remainder. Let us solve the following to revise the concept of division. a) 72 ÷ 9 b) 42 ÷ 3 c) 120 ÷ 5 d) 80 ÷ 4 e) 24 ÷ 1 & Remembering and Understanding In Class 3, we have learnt that division and multiplication are reverse operations. Let us now understand the division of large numbers using multiplication. Division of a 4-digit number by a 1-digit number Dividing a 4-digit number by a 1-digit number is similar to that of a 3-digit number by a 1-digit number. Example 1: Solve: 2065 ÷ 5 Solution: Steps Solved Solve these Step 1: Check if the thousands digit of the dividend is greater than the divisor.

Checking for the correctness of division: We can check whether our division is correct or not using a multiplication fact of the division. Step 1: Compare the remainder and the divisor. [Note: The remainder must always be less than the divisor.] Step 2: Check if (Quotient × Divisor) + Remainder = Dividend Let us now check if our division in example 2 is correct. Steps Checked Step 1: Remainder < Divisor Dividend = 414 Step 2: (Quotient × Divisor) + Divisor = 12 Remainder = Dividend Quotient = 34 Remainder = 6 6 < 12 (True) 34 × 12 + 6 = 414 408 + 6 = 414 414 = 414 (True) Note: a) If remainder > divisor, the division is incorrect. b) If (Quotient × Divisor) + Remainder is not equal to Dividend, the division is incorrect. Dividing a 4-digit number by a 2-digit number Dividing a 4-digit number by a 2-digit number is similar to dividing a 3-digit number by a 2-digit number. Let us understand this through the following example. Example 3: Solve: 2340 ÷ 15 Solution: Steps Solved Solve these Step 1: Check if the thousands digit 2 is not greater than 15.

If this is 2340 + 0 = 2340 false, the division is incorrect. 2340 = 2340 (True) Let us see some properties of division. Properties of division 1) Dividing a number by 1 gives the same number as the quotient. For example: 15 ÷ 1 = 15; 1257 ÷ 1 = 1257; 1 ÷ 1 = 1; 0 ÷ 1 = 0 2) Dividing a number by itself gives the quotient as 1. For example: 15 ÷ 15 = 1; 1257 ÷ 1257 = 1; 1 ÷ 1 = 1 3) Division by zero is not possible and is not defined. For example: 10 ÷ 0; 1257 ÷ 0; 1 ÷ 0 are not defined Division 7 NR_BGM_9789386663351 MAPLE G04 INTEGRATED TEXTBOOK TERM 2_Text.pdf 43 1/7/2019 2:57:08 PM

Chapter Fractions - I 8 Let Us Learn About • e quivalent fractions. • p roblems related to equivalent fractions. • like and unlike fractions. • adding and subtracting like fractions. Concept 8.1: Equivalent Fractions Think Jasleen cuts 3 apples into 18 equal pieces. Ravi cuts an apple into 6 equal pieces. Did both of them cut the apples into equal pieces? Recall In Class 3, we have learnt that a fraction is a part of a whole. A whole can be a region or a collection. When a whole is divided into two equal parts, each part is called ‘a half’. 11 22 ‘Half’ means 1 out of 2 equal parts. We write ‘half’ as 1 . 2 10 1/7/2019 2:57:08 PM NR_BGM_9789386663351 MAPLE G04 INTEGRATED TEXTBOOK TERM 2_Text.pdf 46

Two halves make a whole. Numerator Numbers of the form Denominator are called fractions. The total number of equal parts into which a whole is divided is called the denominator. The number of such equal parts taken is called the numerator. Similarly, each of the three equal parts of a whole is called a third. We write one-third as 1 and, two-thirds as 2 . 33 3 Three-thirds or 3 make a whole. Each of four equal parts of a whole is called a fourth or a quarter written as 1 . 4 Two such equal parts are called two-fourths, and three equal parts are called three-fourths, written as 2 and 3 respectively. Four quarters make a whole. 44 2 halves, 3 thirds, 4 fourths, 5 fifths, …, 10 tenths make a whole. So, we write a whole as 2 , 3 , 4 , 5 ,...,10 and so on. 2 3 4 5 10 & Remembering and Understanding Fractions that denote the same part of a whole are called equivalent fractions. Let us now understand what equivalent fractions are. Suppose there is 1 bar of chocolate with Ram and Raj each as shown. chocolate with Ram chocolate with Raj Ram eats 1 of the chocolate. 5 Then the piece of chocolate he gets is Raj eats 2 of the chocolate. 10 Then the piece of chocolate he gets is Fractions - I 11 NR_BGM_9789386663351 MAPLE G04 INTEGRATED TEXTBOOK TERM 2_Text.pdf 47 1/7/2019 2:57:08 PM

We see that both the pieces of chocolates are of the same size. So, we say that the fractions 1 and 2 are equivalent. We write them as 1 = 2 . 5 10 5 10 Example 1: Shade the regions to show equivalent fractions. a) [ 1 and 2 ] 36 b) [ 1 and 2 ] 48 Solution: a) 1 3 2 6 b) 1 4 2 8 Example 2: Find the figures that represent equivalent fractions.

Concept 8.3: Add and Subtract Like Fractions Think Jasleen has a cardboard piece, equal parts of which are coloured in different colours. Some of the equal parts are not coloured. She wants to find the part of the cardboard that has been coloured and left uncoloured. How do you think Jasleen can find that? Recall Recall that like fractions have the same denominators. To compare them, we compare their numerators. Let us answer the following to recall the concept of like fractions. Compare the following using >, < and =. a) 2 ____ 1 b) 4 ____ 8 c) 3 ____ 5 d) 7 ____ 3 e) 1 ____ 4 33 10 10 77 88 55 & Remembering and Understanding While adding or subtracting like fractions, add or subtract only their numerators. Write the sum or difference on the same denominator. Let us understand addition and subtraction of like fractions through some examples. Example 13: In the given figures, find the fractions represented by the shaded parts using addition. Then find the fractions represented by the unshaded parts using subtraction. a) b) c) Solution: We can find the fractions represented by the shaded and the unshaded parts with the following steps. 20 1/7/2019 2:57:08 PM NR_BGM_9789386663351 MAPLE G04 INTEGRATED TEXTBOOK TERM 2_Text.pdf 56

She sat on the bed beside her son and asked him, ‘Have you read about Kalpana Chawla?’ Barun started reading about Kalpana Chawla in the evening. Kalpana Chawla was born in 1962 in Karnal in the state of Haryana. Nicknamed ‘Montu’ by her family, she went to school at the age of three. Later, she studied Aeronautical Engineering at Punjab Engineering College, India. In 1982, Kalpana went to the USA to study at the University of Texas at Arlington. In 1988, she became a research scientist at NASA Ames Research Center in Sunnyvale, California. In November 1996, Kalpana joined the STS-87 mission aboard the space shuttle Columbia. The mission flew in November–December 1997, during Kalpana Chawla which Kalpana spoke with the then Prime Minister of India, Mr Inderjit K Gujral, from the orbit. On 16 January 2003, Kalpana again went into space. She was on board the space shuttle Columbia. After a successful flight, Columbia was lost with its crew during reentry into the Earth’s atmosphere on 1 February 2003. A hill on Mars and a star in deep space have been named after Kalpana. Her story shows the value of hard work and sincerity that is remembered even when one is no more. NR_BGM_9789386663368 MAPLE G04 INTEGRATED TEXTBOOK TERM 3_Text.pdf 13 11 1/7/2019 3:00:18 PM

Kite flying is one of the world’s oldest sports. In China, people used to fly different coloured kites to send different messages. No one knows for certain who invented kites. Some historians believe that the Egyptians were the first to fly kites. Ancient Egyptian carvings depict men flying objects attached to strings. Some believe that Ancient Greeks invented kites, while others believe that the Chinese made the first kites. 12 1/7/2019 3:00:18 PM NR_BGM_9789386663368 MAPLE G04 INTEGRATED TEXTBOOK TERM 3_Text.pdf 14

Throughout the centuries, kites have been used for various purposes. Once, a Chinese emperor who had been imprisoned was saved by a kite. His followers flew a huge kite over the tower in which the emperor was imprisoned. Recognising the kite, he took hold of the huge ropes hanging from the kite and flew away to freedom. Benjamin Franklin used a kite to prove that lightning is a form of electricity. He flew a kite in a thunderstorm and was almost killed when lightning travelled down the wet string and lit up his instruments. The kite was also responsible for the invention of aeroplanes. The Wright Brothers flew many kinds of kites and studied their movements before making the first aeroplane. Actually, the first aeroplane was a huge kite glider that was specially made to carry an engine and a person. 1) Which is one of the world’s oldest sports?

R5 Reading Comprehension Passage 1 Read the story and answer the questions given below. Spit keeps our mouths moist and softens our food when we chew. Without spit in our mouths, we would have a hard time talking and swallowing. But for some animals, spit works better after it has left the mouth. Some animals are experts at surviving because they are expert spitters. Llamas are animals that like their personal space. A llama that feels threatened or annoyed will spit slimy gobs at you to get you to leave it alone. Sometimes, llamas even spit on each other to steal food! Llama spit includes food from the llama’s stomach, and it can be quite smelly. When a llama spits on another animal, the animal usually loses its appetite and walks away, leaving its food behind. The archer-fish is a very skilled llamas spitter. It takes aim and spits jets of water at insects and other small creatures to knock them into the water. Then, it gulps them down quickly. Spitting cobras are also known for their expert aim. These snakes spray venom from their fangs to protect themselves. Scientists believe that these snakes actually aim for the eyes! When a cobra’s venom gets into the eyes of an animal, the venom causes terrible pain and even blindness. This gives the snake plenty of time to get away. 1) How does spit help human beings?

Bullying is being unkind to another person again and again. Bullying can be of many types. It can be teasing, threatening to hurt someone or telling lies about someone. Yelling at someone, hitting them or excluding them can also be bullying. Being bullied makes people feel powerless, sad and alone. It can be difficult to stand up for yourself when you are being bullied. The bully seems more powerful than you. Being bullied can lead to illness or problems at school. It can also result in some people turning into bullies themselves. Reading Comprehension 33 NR_BGM_9789386663368 MAPLE G04 INTEGRATED TEXTBOOK TERM 3_Text.pdf 35 1/7/2019 3:00:19 PM

There are a lot of reasons why bullying happens. Some want to copy their friends. Some think that being a bully will make them respected or popular. Sometimes bullies think that they are better than their peers, and so they bully them to prove it. Bullies use power to hurt people. Bullies might use physical strength. They might use their popularity or smartness in school. Or they may use secrets they know to hurt others. No matter what the reasons behind it are, or how it is done, bullying is wrong! Bullying isn’t just bad for the victim being bullied. It’s bad for the bully too. Those who are bullies often grow up to have problems like getting into fights. You may not know what to do if you witness bullying. It may make you feel depressed or worried. You may not feel safe. These feelings may make you want to join in the bullying, or be silent, so as not to get bullied yourself. Or perhaps the bullying makes you so angry that you stand up to the bully yourself. The best and safest thing to do is to inform an adult whom you trust so that they can help put a stop to it. 1) What are the different ways by which bullying can happen? Ans.   2) What can you do if you see somebody getting bullied? Ans.   3) Change the given sentences by following the instructions in brackets. a) Bullying can be of many ways.
