Slide Deck

Welcome to Binary Basics

Understanding the language of computers: Binary Numbers.

Introduce the topic by explaining that binary is the language of computers. It's a base-2 number system that uses only two digits: 0 and 1.

What is Binary?

Binary is a base-2 number system.

  • Uses only two digits: 0 and 1.
  • Each digit is called a 'bit'.

Explain that binary is a base-2 number system, unlike the decimal system which is base-10. Each binary digit is called a bit.

Binary in Computers

Computers use binary to process and store data.

  • Each bit represents a power of 2.
  • Multiple bits can represent larger numbers.

Discuss how binary is used in computers to represent data. Each bit can be a 0 or a 1, and combinations of bits can represent complex data.

Converting Decimal to Binary

Example: Convert 13 to binary.

  1. 13 ÷ 2 = 6 remainder 1
  2. 6 ÷ 2 = 3 remainder 0
  3. 3 ÷ 2 = 1 remainder 1
  4. 1 ÷ 2 = 0 remainder 1
    Binary: 1101

Show how to convert a decimal number to binary using the method of dividing by 2 and recording the remainders.

Converting Binary to Decimal

Example: Convert 1101 to decimal.

  1. (1 × 2^3) + (1 × 2^2) + (0 × 2^1) + (1 × 2^0)
  2. 8 + 4 + 0 + 1 = 13

Explain how to convert binary numbers back to decimal by multiplying each bit by its corresponding power of 2 and summing the results.

Bits and Bytes

  • A byte is 8 bits.
  • Can represent 256 different values (0-255).
  • Used to encode characters in text.

Introduce the concept of bytes, which are groups of 8 bits, and how they are used to represent larger data values.

Summary

  • Binary is the foundation of computer data.
  • Conversion between binary and decimal is crucial.
  • Bits and bytes are basic units of data.

Summarize the key points covered in the lesson and prepare students for the hands-on activities and quiz.

Activity

Binary Beads Activity

Objective

To help students understand binary numbers by creating physical representations using beads.

Materials Needed

Instructions

  1. Introduction

    • Explain that each bead represents a binary digit (bit).
    • Use one color for '0' and another color for '1'.

  2. Creating Binary Numbers

    • Provide each student with a string and a set of beads.
    • Ask students to create a binary number using the beads. For example, to represent the binary number 101, they would place beads in the order of the colors representing 1, 0, and 1.

  3. Decoding Binary Numbers

    • Once students have created their binary numbers, ask them to decode the numbers back into decimal form.
    • Use the Binary Concepts Slide Deck to help students understand the conversion process.

  4. Discussion

    • Discuss how binary numbers are used in computers and why understanding them is important.
    • Encourage students to share their bead creations and explain the binary numbers they represented.

Follow-Up Questions

  • How does changing the order of beads affect the binary number?
  • What challenges did you face while creating or decoding the binary numbers?
  • How might this activity help you understand how computers store and process data?

Conclusion

  • Summarize the activity by reinforcing the concept that binary numbers are the foundation of computer data.
  • Encourage students to practice creating and decoding more binary numbers using beads or other materials at home.
