Introduction & Learning Objectives

Learning Objectives Identify a simple repeating pattern of shapes. Describe the 'rule' of a simple pattern. Extend a given shape pattern by one or two items. Create their own simple AB or AAB shape pattern. Find the missing shape in a simple pattern. Explain their pattern's rule to a friend. Look at a stripy sock! 🧦 What color do you think comes next? Today, we will be pattern detectives! πŸ•΅οΈ We will find, finish, and create our own shape patterns. This helps us tell computers what to do, step-by-step. Real-World Applications Songs have repeating sounds and words. 🎢 A necklace has beads in a special order. κΏ° A ladybug has spots in a pattern. 🐞 Day and night is a pattern. β˜€οΈπŸŒ™

Key Concepts & Vocabulary

TermDefinitionExample PatternA pattern is something that repeats over and over again.Example: πŸ”΅πŸŸ‘πŸ”΅πŸŸ‘πŸ”΅πŸŸ‘... RuleThe rule tells us the special order of the pattern.For πŸ”΅πŸŸ‘πŸ”΅πŸŸ‘, the rule is 'first a blue circle, then a yellow circle'. RepeatTo do or show something again and again.In the pattern 🐢🐱🐢🐱, the dog and cat repeat. SequenceA list of things that are in a special order.The pattern πŸ”Ίβ¬œοΈπŸ”Ίβ¬œοΈ is a sequence of shapes. PredictTo make a smart guess about what will come next.In 🍎🍌🍎🍌, I predict an apple 🍎 comes next. Core UnitThe smallest part of the pattern that repeats.In πŸš—πŸ§ΈπŸš—πŸ§Έ, the core unit is 'car, teddy bear' (πŸš—πŸ§Έ).

Core Syntax & Patterns

Find the Rule Look at the shapes. Find the small part that repeats. Do this first to understand how the pattern works. What Comes Next? Say the pattern out loud. The next sound is the next shape. Use this trick to help you finish a pattern. Make Your Own Pattern 1. Pick two shapes. 2. Put them in an order. 3. Repeat! Follow these steps to create your very own cool patterns.
