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? ๐Ÿฆ“ They repeat! That's a pattern! Today, we will be super detectives! ๐Ÿง We will learn how to find secret patterns. Finding patterns helps us understand the world. Real-World Applications Songs have repeating words (a chorus) ๐ŸŽถ Days of the week follow a pattern ๐Ÿ—“๏ธ Traffic lights change in a pattern: Red, Yellow, Green ๐Ÿšฆ Bricks on a wall often make a pattern ๐Ÿงฑ

PatternA pattern is something that repeats over and over again in a special order. โœจCat ๐Ÿฑ, Dog ๐Ÿถ, Cat ๐Ÿฑ, Dog ๐Ÿถ... is a pattern. RuleThe rule tells us HOW the pattern repeats. It's the secret instruction! ๐ŸคซFor ๐ŸŽ, ๐ŸŒ, ๐ŸŽ, ๐ŸŒ... the rule is 'First an apple, then a banana'. SequenceA sequence is a list of things that are in a special order. โžก๏ธThe numbers 1, 2, 3, 4 are a sequence.

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.
