• Numbers are arranged in a pattern based on the addition, subtraction, multiplication, etc.

• Patterns are arrangements in particular style.
• Patterns can be made up of numbers, sizes, shapes, etc.
• In the number series numbers are arranged in different patterns

#### Concept of Patterns

Introduction     In this chapter, you will learn various patterns based on shape size and number.      Concept of Patterns   Patterns are particular arrangements. For example, let's see the following patterns of numbers:
 1 2 3 4 5 6
Ascending Order Pattern                                                                                        or
 6 5 4 3 2 1
Descending Order Pattern     Similarly other patterns are made in different forms. See another following patterns:                    Patterns            What will come in the blank circle?

#### Introduction

Introduction     The kilometer, metre, centimeter, inches and foot are the units of distance and length. While kilometer andmetre are used for long and average distances, and length, centimeter, inches and foot are used to measure short distances.      Length and Breadth Length is longer dimension of an object while breadth is the dimension from side to side. Let's see the picture given below:       Measurement In the above mentioned picture, the longer dimension is AB and CD. Hence AB and CD are lengths. While dimension from side to side are AC and BD and it is called breadth.     Now Remember, kilometer =metre metre = centimeter andfoot =inches. Now ifkilometer =metre thenkilometer = Twometers. Kilometer = Threemeters and the process goes on.     Similarly, metre =centimeters. metre = twocentimeters meters = threecentimeters and the process goes on. Againfoot =inches. foot = twoinches =inches. foot = threeinches = inches.     Remember again   Short forms: Kilometer            =         Metre                   =          Centimeter        =                         How many kilometers are there in two 1000 meters? (a) 4                                                       (b) 2 (c) 3                                                       (d) 5     Answer: (b) Explanation kilometer = onemeters then kilometers = two meters.        Which one of the following is the length in the given picture?     (a) LM                                                   (b) LN (c) MO                                                  (d) NL     Answer: (a)
• There are 12 inches in 1 foot.
• Generally the length of a football field is 110 meters but it varies from country to country.

#### Identifying Notes

Identifying Notes   The information that is required to identify the rupees are written on a paper and is called Notes. In India, 1 rupee, 2 rupees, 5 rupees, 10 rupees, 20 rupees, 50 rupees, 100 rupees, 500 rupees and 1000 rupees Notes are in circulation.   Look at the 1 rupee and 2 rupees notes given below:       1 rupee (One rupee note)                  2 rupees (Two rupee note)   It is clear from the picture given above that denomination or value of notes written on it. Therefore, whenever we identify the note we see the denomination or value written on it.     100 rupees (One hundred rupees note)   500 rupees (Five hundred rupees note)                                                          1000 rupees (One thousand rupees note)     50 rupees (Fifty rupees note)       5 rupees (Five rupees note)              Identify the note given in the picture and pick the correct option. (a) It is a 20 rupees note               (b) It is a 5 rupees note (c) It is a 50 rupees note                (d) It is a 10 rupees note   Answer: (d)            Which one of the following options has similar value of the given Note? (a) 10 notes of 100 rupees           (b) 5 notes of 500 rupees (c) 5 notes of 100 rupees              (d) 5 notes of 50 rupees   Answer: (a) Explanation The given note is of Rs. 1000 which has similar value of 10 notes of Rs. 100.
