Patterns

Generic topic

This topic comes from GayaGnan's India-wide K–12 catalog. It is not copied from, or an official chapter of, any board's textbook: check your board's syllabus for the exact chapter and depth.

🎯 Learning outcomes

  • Identify the rule in a repeating pattern
  • Extend shape, colour and number patterns
  • Make their own pattern and explain it

Before you start: Naming shapes and counting.

📖 Explanation

A pattern is something that repeats or grows by a rule. Red, blue, red, blue repeats a group of two.

To continue a pattern, find the part that repeats (the core) or the change between steps. In 2, 4, 6, 8 the numbers grow by 2 each time, so 10 comes next.

Patterns are everywhere: on sarees, tiles, in music beats and in the days of the week.

🇮🇳 Example from India

Kolam designs in Tamil Nadu repeat loops and dots in a regular pattern across the doorway.

⚠️ Common mistake

✗ Any list of things is a pattern
✓ A pattern must follow a rule that lets you say what comes next.

Clap and stamp a pattern (clap, clap, stamp). Friends copy it and add three more beats.
