Introduction & Learning Objectives
Learning Objectives
Identify a simple repeating color pattern.
Describe the 'rule' of a color pattern (e.g., 'red, blue, red, blue').
Continue a given color pattern with the next correct color.
Find and fix a mistake in a simple color pattern.
Create their own simple AB, AAB, or ABC color pattern using objects.
Explain that computers use patterns to do jobs.
Look at this line of toys! π§Έππ§Έπ What toy do you think comes next?
We are going to be color detectives! π΅οΈββοΈ We will learn to find secret codes called patterns. Finding patterns helps us tell computers what to do.
Real-World Applications

Key Concepts & Vocabulary
TermDefinitionExample
PatternA pattern is something that repeats over and over again.Red, blue, red, blue, red, blue... π΄π΅π΄π΅π΄π΅
RuleThe rule is the special order of the pattern.In a π΄π΅π΄π΅ pattern, the rule is 'one red, then one blue'.
RepeatTo repeat means to do or show something again.In ππππππ, the 'two apples, one banana' part repeats.
SequenceA sequence is a list of things in a special order.A traffic light sequence is green, then yellow, then red. π¦
AlgorithmAn algorithm is a list of steps to follow. It is like a recipe!Our pattern rule is an algorithm for making the pattern.
PredictTo predict is to guess what comes next using the pattern's rule.In πΆπ±πΆπ±, I predict a dog πΆ comes next.

Core Syntax & Patterns
The 'Look and Say' Rule
Look at the colors. Say them out loud. Find the part that repeats.
Use this first to understand any pattern you see.
The 'What's Next?' Rule
1. Find the repeating part. 2. Use it to predict the next color.
Use this rule to continue or finish a pattern.
The 'Build Your Own' Rule
1. Pick a few colors. 2. Make a small group. 3. Repeat it!
Use this to create your very own new patterns.
