Create their own simple pattern using two or three items.
Find patterns in everyday objects like clothes or songs.
Explain that a pattern is something that repeats.
Look at a ladybug's spots! đ Do you see a pattern? Let's be pattern detectives!
We will learn how to find patterns all around us. Finding patterns helps us guess what comes next!

Core Syntax & Patterns
Find the Core
Look for the smallest group of items that repeats.
Finding the core helps you understand the whole pattern.
Say the Rule
Use words like 'First..., then...' to describe the core.
This helps you tell a friend how to make the same pattern.
Check and Continue
Check if the pattern keeps repeating. Then add the next part.
This is how you make a pattern longer or fix a mistake.
