Specific Objectives: At the end of this class, Student will be able to: Undersanding the concepts of number system Explain the binary and decimal number system Convert between decimal to binary number system
Teaching Materials: Marker, dustor and Whiteboard; Laptop and projector.
Introduction: Start by asking a questoions about previous knowledge of Number system; Encourage them to share their thought; Introduce the number system: Number system is a technique to represent and work with numbers is called number system. Decimal number system is the most common number system. Other popular number systems include binary number system, octal number system, hexadecimal number system, etc. Types: Binary Number system Decimal number system Octal number system Hexadecimal number system
1) Binary Number System A Binary number system has only two digits that are 0 and 1. Every number (value) represents with 0 and 1 in this number system. The base of binary number system is 2, because it has only two digits. These number represent two logical conditions:TRUE and FALSE. Table: Decimal number system: Decimal number system has only ten (10) digits from 0 to 9.
Every number (value) represents with 0,1,2,3,4,5,6, 7,8 and 9 in this number system.
The base of decimal number system is 10, because it has only 10 digits. Binary to decimal conversion Discuss the process of converting Binary to decimal show and practice the some examples: Example 1: Example 2: Decimal to Binary Conversion: Discuss the process of converting Decimal to binary Introduce methods like division by 2 and remainders. Show and practice the some examples: Example 1: Example 2:
Class-room activity: Assign a class-work for students: Task 1:Convert 1110 into a decimal Task 2:Convert (17)10 as a binary number Task 3:Convert (225)10 into a binary Task 4:Convert 1001 into decimal Walk around to assist students and answer and questions. Conclusion: Summarize a key points(Number system , Binary number and decimal number) Encourage the students to ask the questions Assessment: Define Number system and its type. Convert the following binary number in decimal equivalents: 00111 01011 Convert the following decimal number in binary equivalents: (158)10 (260)10
