Introduction & Learning Objectives
Learning Objectives
Identify the core repeating unit in a simple pattern.
Describe a pattern's rule using words (e.g., 'one red, one blue').
Create a simple AB pattern using physical objects like blocks or toys.
Create a more complex AAB or ABC pattern.
Extend an existing pattern by adding the next three items.
Explain why patterns are like instructions for a computer.
Have you ever made a tower with blocks? π§± Let's see... red, blue, red, blue. That's a pattern!
Today, we will be pattern creators! π¨ We will learn how to make our own cool patterns. This helps us give clear instructions, just like we do for computers.

Key Concepts & Vocabulary
TermDefinitionExample
PatternA pattern is something that repeats over and over again. It follows a rule.Cat, Dog, Cat, Dog... π±πΆπ±πΆ This is a pattern.
RuleThe rule is the secret code for the pattern. It tells you what comes next.For π±πΆπ±πΆ, the rule is: 'First a cat, then a dog'.
Core UnitThis is the smallest part of the pattern that repeats.In π±πΆπ±πΆ, the core unit is just 'Cat, Dog' (π±πΆ).
RepeatTo repeat means to do the same thing again and again.We repeat the π±πΆ part to make the pattern longer.
SequenceA sequence is a list of things that are in a special order.Our pattern π±πΆπ±πΆ is a sequence.
AlgorithmAn algorithm is a list of steps to finish a task. A pattern rule is a small algorithm!The rule 'First a cat, then a dog, then repeat' is an alg...

Core Syntax & Patterns
The AB Pattern
Item A, Item B, Item A, Item B...
Use this for a simple pattern. Pick two different things and switch between them.
The AAB Pattern
Item A, Item A, Item B, Item A, Item A, Item B...
Use this to make it more interesting. Use the first item twice, then the second item once.
The ABC Pattern
Item A, Item B, Item C, Item A, Item B, Item C...
Use this for a longer pattern. Pick three different things and put them in order.
