Objective

By the end of this lesson, you will be able to apply arithmetic concepts to solve problems related to computer science and programming.

Materials and Prep

Materials: Pen or pencil, paper, computer with internet access.

Prior Knowledge: Basic understanding of arithmetic operations such as addition, subtraction, multiplication, and division.

Activities

1. Explore the concept of binary numbers and how they are used in computer programming.

2. Practice converting decimal numbers to binary and vice versa.

3. Solve word problems involving binary numbers and arithmetic operations.

Eighth Grade Talking Points

• Binary numbers are a fundamental part of computer science. They consist of only 0s and 1s, and computers use them to represent data and perform calculations. You can say, "Computers speak in a language of 0s and 1s, just like how we use numbers to communicate with each other."
• Converting decimal numbers to binary is like translating between two different languages. You can say, "When we convert a decimal number to binary, we are essentially breaking it down into a series of 0s and 1s that the computer can understand."
• Word problems involving binary numbers and arithmetic operations help us see the real-world applications of mathematics in computer science. You can say, "By solving these problems, we can understand how arithmetic is used to solve practical problems in computer programming."
