Conditions & Logic: If-Then Rules
Grade 3-5 Technology Lesson 2: Understanding Conditional Statements 60-minute Interactive Learning Experience
Quick Recap Challenge
What did we learn about sequencing yesterday? Can you give an example of a sequence from your morning routine? Why is the ORDER of steps important?
Today's Learning Goals
Understand what conditions and logic mean Learn how IF-THEN rules work Practice making decisions based on conditions Apply conditional thinking to real-world situations
What Are Conditions?
A condition is a situation or circumstance It's like asking a YES or NO question Examples: Is it raining? Are you hungry? Is the light on? Conditions help us make decisions
The Magic of IF-THEN
IF something happens, THEN we do something else It's like a rule that computers (and people) follow IF it's raining, THEN take an umbrella
Follow the Leader: IF-THEN Edition
Student leader gives IF-THEN commands Followers must listen carefully and act only when the condition is met Example: 'IF I clap my hands, THEN hop on one foot' Take turns being the leader
Rock, Paper, Scissors Logic
{"left":"IF Rock vs Scissors, THEN Rock wins\nIF Paper vs Rock, THEN Paper wins\nIF Scissors vs Paper, THEN Scissors win","right":"IF both players choose the same, THEN it's a tie\nEvery game outcome follows these IF-THEN rules\nThe computer uses the same logic to determine winners"}
Real-World IF-THEN Examples
IF the traffic light is red, THEN stop IF you're hungry, THEN eat food IF it's bedtime, THEN brush your teeth IF the phone rings, THEN answer it Can you think of more examples?
Create Your Own IF-THEN Rules
Work with a partner Think of 2 real-world IF-THEN rules One for home, one for school Share with the class Example: IF homework is finished, THEN you can play games
What We Learned Today
Conditions are like YES/NO questions IF-THEN rules help us make decisions Computers use conditional logic just like we do These rules are everywhere in our daily lives Next lesson: We'll learn about loops and repetition!
