📚 Topic Summary
The 'if-then-else' concept is a fundamental building block in computer programming. It's a way for a program to make decisions based on different conditions. In simple terms, 'if' something is true, 'then' do this, 'else' do that. This activity explores these concepts in a fun, unplugged way, showing how choices are made based on specific conditions, just like a computer program!
Imagine you're deciding what to wear. If it's raining, then take an umbrella. Else, you don't need one. That's 'if-then-else' in action! This worksheet will help you understand how these simple decisions can create complex outcomes.
