Introduction & Learning Objectives
Learning Objectives
Identify a simple repeating pattern.
Describe the rule of a pattern using words.
Continue a given pattern with the next item.
Predict what comes next in a sequence.
Create their own simple pattern using objects.
Spot patterns in everyday things like songs or clothes.
Have you ever noticed the stripes on a zebra? ๐ฆ They repeat! That's a pattern!
Today, we will be super detectives! ๐ง We will learn how to find secret patterns. Finding patterns helps us understand the world.

PatternA pattern is something that repeats over and over again in a special order. โจCat ๐ฑ, Dog ๐ถ, Cat ๐ฑ, Dog ๐ถ... is a pattern.
RuleThe rule tells us HOW the pattern repeats. It's the secret instruction! ๐คซFor ๐, ๐, ๐, ๐... the rule is 'First an apple, then a banana'.
SequenceA sequence is a list of things that are in a special order. โก๏ธThe numbers 1, 2, 3, 4 are a sequence.
PredictionA prediction is a smart guess about what will come next in a pattern. ๐ฎIn the pattern โ๏ธ, ๐, โ๏ธ, ๐... I predict a โ๏ธ is next.

Core Syntax & Patterns
Look for the Repeating Part
Find the smallest group of things that happens again and again.
Use this to find the 'core' of the pattern. Look closely at the data.
Follow the 'What's Next' Rule
Once you find the repeating part, use it to know what comes next.
This helps you continue the pattern or predict the next item.
