Lesson Plan: Coding Your World with "If-Then" Superpowers

Materials Needed

• Whiteboard or large piece of paper
• Markers or pens
• Index cards or small pieces of paper (about 10-15)
• Household items for an obstacle course (e.g., pillows, books, toys, tape for a finish line)
• A favorite toy or stuffed animal (optional)

Learning Objectives

By the end of this lesson, you will be able to:

• Explain what a command is in your own words.
• Create simple "If-Then" rules to solve a problem.
• Write a short sequence of commands (an algorithm) to guide a "robot" through a task.
• Work together to test and fix your commands.

Lesson Activities

1. Introduction: The Superpower of Instructions (5 minutes)

Hook: A Quick Game

Let's start with a game. I'm going to give you some secret rules.

• Rule 1: IF I clap my hands once, THEN you stand up.
• Rule 2: IF I clap my hands twice, THEN you sit down.

(Educator claps once, then twice, then once again, making sure learners follow the rules. Celebrate their success.)

Connect to Coding

Educator says: "You just followed a code! Computers and robots aren't super smart on their own. They need us to give them very clear instructions, just like the ones I gave you. These special instructions are called a program or an algorithm. Today, we're going to learn how to write our own programs using the 'If-Then' superpower, which is one of the most important ideas in all of coding."

2. Body: Learning the Code

Part A: I Do - What is an "If-Then" Rule? (5 minutes)

Educator says: "An 'If-Then' rule tells a computer what to do when something specific happens. The 'IF' part is the condition—it's what the computer checks for. The 'THEN' part is the action—it's what the computer does."

(Write on the whiteboard)

IF (this thing happens), THEN (do this action).

Educator demonstrates with examples:

• "Here's one from my life: IF it is raining outside, THEN I grab my umbrella. The condition is 'it is raining,' and the action is 'grab my umbrella'."
• "Here's one for a video game: IF the player pushes the jump button, THEN the character jumps on the screen."

Part B: We Do - Let's Make Rules Together (10 minutes)

Educator says: "Now, let's make some 'If-Then' rules together. I'll give you the 'IF' part, and you work together to come up with a good 'THEN' part."

(Write these on the whiteboard and have the learners fill in the blanks.)

• Scenario 1: IF the traffic light is red, THEN... (we stop the car).
• Scenario 2: IF I feel hungry, THEN... (I get a healthy snack).
• Scenario 3: IF my pet looks sad, THEN... (I give it a pat).

Discussion Question: "What would happen if the instructions weren't clear? What if the rule was just 'IF the light is red, THEN go'? That would be a bug, or a mistake in our code!"

Part C: You Do - Program Your Robot! (15-20 minutes)

Educator says: "It's time to be real coders! We're going to build a simple obstacle course. One of you will be the 'Robot,' and the other will be the 'Coder.' The Coder's job is to write the program to get the Robot to the finish line. Then you'll switch roles!"

Set-up:

1. Use pillows, toys, and books to create a simple path from a starting point to a finish line.
2. The Coder gets the index cards and a marker.

Instructions:

1. The Coder writes down at least 3 'If-Then' command cards for their Robot.
2. The Robot closes their eyes (or turns around) while the Coder writes the program.
3. When ready, the Coder reads the commands one by one, and the Robot follows them EXACTLY.
4. The goal is for the Robot to reach the finish line. If something goes wrong, you have to 'debug' or fix your code together!

Success Criteria (What a good program looks like):

• Each card has a clear 'If' condition and a clear 'Then' action.
• The commands are in a logical order.
• The Robot can follow the instructions without needing extra help.

Differentiation:

• For Troy (age 7): Focus on simple commands. You can draw pictures instead of writing words! For example: IF [picture of a pillow], THEN [picture of a person jumping]. Your main goal is to make one or two clear rules.
• For Vienna (age 11): Challenge yourself! Try making an "If-Then-Else" rule. For example: "IF you see a book, THEN step over it, ELSE walk forward two steps." Can you create a program with at least 5 commands?

(Educator observes, helps learners clarify their instructions, and encourages teamwork for debugging.)

3. Conclusion: You're a Coder! (5 minutes)

Recap and Share

Educator asks:

• "What was the most important part of giving instructions to your robot?"
• "Can you give me one example of an 'If-Then' rule you used in your game?"
• "Where else in real life do you think we see 'If-Then' rules? (Think about video games, chores, or even recipes!)"

Reinforce Takeaways

Educator says: "Great job today! You learned that coding is just about giving very clear instructions. You used 'If-Then' logic to solve a problem, worked together to test your program, and even fixed bugs. You have the mind of a programmer!"

Assessment (Show What You Know)

• Formative (During the lesson): Observe learners' ability to create logical "If-Then" statements during the "We Do" activity. Watch how they write and execute their programs in the "You Do" activity. Are their instructions clear? Does the robot follow them correctly?
• Summative (At the end): For a final challenge, have Troy and Vienna work together to write a 2-card "program" to get a toy or stuffed animal from the start to the finish line of the obstacle course. They must present their code and then demonstrate that it works. This shows they can apply the concept together.
