Introduction
Patterns are repetitive sequences of shapes, colors, or numbers that follow a specific rule. In geometry and art, we often use freehand shapes to create beautiful and continuous designs.
Explanation Step by Step
To understand freehand patterns, we look for a unit of repetition. This is the basic shape or set of shapes that repeats itself over and over again to form a sequence.

Sub-topics
Patterns - Freehand shapes
Freehand shapes are drawings made without using tools like rulers or compasses. These include waves, curves, leaves, and simple loops. When these shapes are arranged in a specific order, they create a freehand pattern.
Examples
Example 1
Identify the pattern: ★★ ◯ ★★ ◯ ★ ★◯ ___?
The rule here is (★★, ◯). The next shape will be '★ ★'.
Tricks and Shortcuts
To find the next shape quickly, identify the smallest group of shapes that repeats. This is called the "Pattern Core." Once you find the core, just repeat it.
Common Mistakes
Students often forget to maintain the size of freehand shapes. While freehand shapes are natural, they should look similar in size to keep the pattern consistent.

Revision Summary
Patterns are formed by repeating a specific rule. Freehand patterns use natural shapes like curves and waves. Always look for the repeating core to extend the sequence.
