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! 🍎🍌🍎🍌... What do you think comes next? πŸ€” Today, we will become pattern detectives! πŸ•΅οΈβ€β™€οΈ 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. 🎡 Days of the week follow a pattern. πŸ—“οΈ Traffic lights change in a pattern. 🚦 Brushing your teeth follows a pattern of steps. 🦷

Key Concepts & Vocabulary

TermDefinitionExample PatternA pattern is something that repeats over and over again.The stripes on a zebra are a pattern. πŸ¦“ SequenceA sequence is a list of things in a special order.A line of blocks like this: πŸŸ₯🟦πŸŸ₯🟦πŸŸ₯🟦. RuleA rule tells us how the pattern is made.The rule could be 'First an apple, then a banana'. RepeatTo repeat means to do something again and again.In a song, we repeat the chorus. 🎢 Core UnitThe core unit is the smallest part of the pattern that repeats.In 🐢🐱🐢🐱, the core unit is '🐢🐱'.

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.
