Introduction & Learning Objectives
Learning Objectives
Identify a simple repeating pattern.
Name the core unit of a pattern.
Predict the next item in a sequence.
Extend a given pattern by three items.
Create their own simple AB or AAB pattern.
Explain that patterns are like simple instructions for a computer.
Look at this line of fruit! ππππ... What do you think comes next? π€
Today, we will become pattern detectives! π΅οΈββοΈ We will learn to find and continue patterns. Finding patterns helps us tell computers what to do, step-by-step.
Real-World Applications
Songs have patterns, like verse and chorus. π΅

Core Syntax & Patterns
Find the Core Unit Rule
Look at the sequence. Find the smallest part that repeats.
Use this rule first to understand any pattern. It's the secret code!
What's Next? Rule
Say the core unit out loud. The next item is the start of the core unit again.
Use this rule to continue or finish a pattern.
