Week 2: Thinking Like a Computer

Unit: What is Computer Science? (Weeks 1-2)

What’s in Store This Week?

This week, we’re going to learn the secret to talking to computers! It’s all about thinking like they do. We’ll discover that computers need super clear, step-by-step instructions to get anything done. These special instruction lists are called algorithms, and you use them every day without even realizing it! Through hilarious and hands-on games, you’ll learn how to write your own algorithms and see why being super specific is the key to becoming a master programmer.

What You’ll Be Able to Do!

By the end of this week, you’ll be able to:

  • Explain what an “algorithm” is in your own words (it’s like a recipe!).
  • Write super clear, step-by-step instructions for everyday tasks.
  • Find and fix problems in a set of instructions, a skill called “debugging.”
  • Understand why computers are a bit silly—they do exactly what you tell them, even if it’s wrong!

Lessons This Week

Lesson 2.1: How to Train Your Human Robot

Get Ready To: Become a programmer for a “human robot”! You’ll give commands to your friends and see firsthand why every single step matters.

Lesson 2.2: The Great Peanut Butter Sandwich Challenge!

Get Ready To: Write the most detailed recipe ever for making a peanut butter and jelly sandwich. We’ll test your instructions live, and the results are guaranteed to be funny and educational!

How We’ll See Our Skills Grow

  • Teamwork in Action: We’ll see how well you work as a programmer-robot team.
  • Algorithm Check-Up: We’ll look at the instructions you write to see how clear and complete they are.
  • Before and After: You’ll get to improve your first set of instructions after seeing it in action, showing how much you’ve learned about debugging!

Connecting to Other Subjects

  • Math: You’ll be using logic and putting things in the right order (sequencing).
  • Language Arts: This is all about writing clear instructions that are easy to follow.
  • Life Skills: You’ll get better at following directions for anything, from building LEGOs to baking a cake.

Real-World Connections
