Lesson 3 — Coding Basics
Coding is how we give computers instructions to perform tasks. In this lesson, we’ll explore programming languages, syntax, and logic — and write our first simple program.
Activity 1: Code as Recipes
Writing code is like writing a recipe: instructions must be clear, step-by-step, and leave no room for confusion.
Try this: Write down steps to make a peanut butter & jelly sandwich. Then compare with a detailed version below:
1. Take two slices of bread.
2. Spread peanut butter on one slice.
3. Spread jelly on the other slice.
4. Put the slices together, fillings facing each other.
5. Cut the sandwich in half.
This shows why precision matters in coding!

- What was challenging about writing instructions in the recipe activity?
- If you could write your first computer program, what would you want it to do?
Wrap-Up & Transition
We learned that coding is giving computers precise, step-by-step instructions. Anyone can learn it with practice!
