In this lesson, students are introduced to CodeHS and how Karel the Dog can be given a set of instructions to perform a simple task.
Students will be able to:
Write their first Karel program by typing out all of the Karel commands with proper syntax
Explain how giving commands to a computer is like giving commands to a dog
In this lesson, students learn more about Karel and Karel’s world. Students learn about walls in Karel’s world, the directions Karel can face, and how to identify a location in Karel’s world using rows and columns.

For example, how can they make Karel turn right, even though Karel does not know a turnRight command?
Students will be able to…
In this lesson, students will learn how they can create their own commands for Karel by calling and defining functions. Functions allow programmers to create and reuse new commands that make code more readable and scalable.
