Introduction & Learning Objectives
Learning Objectives
Define an algorithm as a set of steps.
Identify the correct sequence for a simple task.
Create a simple algorithm for a daily routine.
Explain why the order of steps is important.
Find a mistake in a simple, out-of-order algorithm.
How do you make a yummy peanut butter and jelly sandwich? 🥪 What comes first?
We will learn about step-by-step instructions. These are called algorithms! They help us do things in the right order.
Real-World Applications
Following a recipe to bake cookies 🍪
Getting dressed for school in the morning 👕
Building a cool LEGO tower 🧱
Playing a board game with friends 🎲

Key Concepts & Vocabulary
TermDefinitionExample
AlgorithmA list of steps to finish a task. It's like a recipe! 📜The steps to brush your teeth is an algorithm.
SequencePutting steps in the correct order. One thing after another. ➡️First, you put on socks. Then, you put on shoes.
StepOne single instruction in an algorithm. A small action. 🐾A step in making a sandwich is 'get two slices of bread'.
OrderThe special way steps need to be arranged to work. 🔢The order for eating cereal is bowl, then cereal, then milk.
ProgramAn algorithm that you give to a computer to follow. 💻Telling a robot toy to move forward is a simple program.

Core Syntax & Patterns
The 'First, Then, Last' Pattern
Start with 'First...'. Continue with 'Then...'. End with 'Last...'.
Use this to make sure your steps are in a clear order from beginning to end.
The 'One Step at a Time' Rule
Each step should only be one small action. छोटे-छोटे कदम।
Break big tasks into tiny steps. This makes your algorithm easy to follow.
