The clock has two hands: 1) the short hand, known as the ‘hour hand’, and 2) the long hand, called the ‘minute hand’. Reading time When the minute hand points to 12 and the hour hand to any one of the numbers, we read it as the time at that hour. When the hour hand is on 3 and the minute hand on 12, we say it is 3 o’clock. For every one complete round of the minute hand, the hour hand moves forward to the next number. This means that one hour is completed. Example 7: Read the time shown on these clocks. a) b) Solution: We can read the time as: The minute hand is on 12 and the hour hand is on 5. The time is 5 o’clock. a) The minute hand is on 12 and the hour hand is on 8. The time is 8 o’clock. b) 8 1/8/2019 9:10:30 AM NR_BGM_9789386663085 MAPLE G02 INTEGRATED TEXTBOOK TERM 2_Text.pdf 32

Chapter Money 7 Let Us Learn About • adding and subtracting amounts without conversion. • estimation of amounts. Concept 7.1: Add and Subtract Money without Conversion Think David and his mother bought a few items from a shop. When David’s mother paid the bill, the shopkeeper gave her some change. David wondered why the shopkeeper gave his mother some money. Do you know why? Recall We add or subtract numbers by writing them one below the other. This method is called the column method.

In the column method, we write rupees under rupees. Then we write paise under paise, exactly one below the other. When paise is not given, we put 00 in the paise column. Then we add or subtract as usual. Addition of money Let us understand adding amounts through an example. Example 1: Add: ` 45.50 and ` 32.20 Solution: Arrange rupees and paise in two columns.

Chapter Multiplication 8 Let Us Learn About • repeated addition. • skip counting. • multiplication tables from 2 to 6. Concept 8.1: Concept of Repeated Addition Think David has five pet cats. He wants to know the number of legs they have altogether. How can David find that? Recall We already know how to add some objects by counting. Let us recall the same through the following exercise. 18 1/8/2019 9:10:31 AM NR_BGM_9789386663085 MAPLE G02 INTEGRATED TEXTBOOK TERM 2_Text.pdf 42

& Remembering and Understanding Repeated addition is adding the same number repeatedly (again and again). We put the objects into equal groups to find their total. Let us see a few examples. E xample 1: Use repeated addition to find the total number of houses. Solution: Number of groups = 4 The number of objects in each group = 2 Total number of objects = 2 + 2 + 2 + 2 = 8 So, there are 8 houses in all. We read it as 4 groups of 2 is 8. Example 2: Count and add: Solution: Number of groups = 3 Number of equal number of objects in each group = 4 Total number of objects = 4 + 4 + 4 = 12 We read it as 3 groups of 4 is 12. 20 1/8/2019 9:10:31 AM NR_BGM_9789386663085 MAPLE G02 INTEGRATED TEXTBOOK TERM 2_Text.pdf 44
Application Let us now apply the concept of repeated addition. Example 3: Suresh has three pet dogs. How many legs do these dogs have altogether? Solution: Suresh has three pet dogs. So, the number of groups is 3. Each dog has 4 legs. So, the number of equal objects in each group is 4. 4 + 4 + 4 = 12 So, 3 groups of 4 is 12. Therefore, the three dogs have 12 legs altogether. Example 4: A star has 5 corners. How many corners will such 4 stars have? Number of stars (groups) = 4 Solution: Number of corners (objects) in each star = 5 That is, 5 + 5 + 5 + 5 = 20. So, 4 groups of 5 is 20. So, 4 stars have 20 corners. Multiplication 21 NR_BGM_9789386663085 MAPLE G02 INTEGRATED TEXTBOOK TERM 2_Text.pdf 45 1/8/2019 9:10:31 AM
Higher Order Thinking Skills (H.O.T.S.) Let us see an example based on repeated addition. Example 5: Sudha wanted to buy beads to make necklaces for her daughter and for herself. To make a necklace, she needs at least 25 beads. How many beads are needed to make necklaces for both of them? Solution: Number of necklaces (groups) = 2 Number of beads (objects) = 25 That is, 25 + 25 = 50. So, 2 groups of 25 = 50. So, the total number of beads required to make two necklaces is 50. Concept 8.2: Skip Counting Think While playing hopscotch, David knows to jump by skipping some of the boxes. Similarly, he can count numbers by skipping some of them. How could he do that? Recall Recall the concept of repeated addition through these examples.

b) 3 groups of 9 [ ] c) 2 groups of 8 [] d) 6 groups of 1 [] & Remembering and Understanding Skip Counting is counting by a number that is not 1. It helps you • to count many things quickly. • to learn multiplication tables. Count by 2s In counting by 2s, we begin with the given number and count every alternate number.

b) c) Count by 3s In counting by 3s, we count every third number from the given number. Example 7: Begin with the given number and count by 3s. Write the numbers in the boxes given. One is done for you. a) b) c) We now know the concepts of repeated addition and skip counting. Let us now learn to construct the multiplication tables of numbers from 2 to 6. 24 NR_BGM_9789386663085 MAPLE G02 INTEGRATED TEXTBOOK TERM 2_Text.pdf 48 1/8/2019 9:10:31 AM
Observe the following figure. It is a group of 2 stars. So, we see that 1 group of 2 is 2. We write it as ‘2 × 1 = 2’ which means ‘2 times 1 is 2’. The symbol ‘×’ is used for multiplication. It is read as ‘times’. We read it as ‘2 ones are 2’. There are 2 groups with 2 stars in each. We write it as 2 + 2 = 4 and read it as 2 groups of 2 is 4. We can also write it as ‘2 × 2 = 4’ which means ‘2 times 2 is 4’. We read it as ‘2 twos are 4’. These are 3 groups with 2 stars in each. We write it as 2 + 2 + 2 = 6 and read it as 3 groups of 2 is 6. This can be written as ‘2 × 3 = 6’ which means ‘2 times 3 is 6’. We read it as ‘2 threes are 6’. In this way, we can form the multiplication table of 2. Forming the multiplication table of 2 2×1=2 1 + 1 2 times 1 is 2. 2×2=4 2 + 2 2 times 2 is 4.
