Performance objectives

• Patterns, functions, and relationships are all about finding the rules that connect numbers and shapes together. Understanding these rules helps us predict what comes next, solve problems, and see the world in a more organised way. In South Africa, we use patterns every day - from the designs on traditional Ndebele houses to the way vendors arrange their fruit at the market. Learning about patterns helps us appreciate the beauty and logic around us. This week, we'll focus on identifying and extending number patterns, describing the rules that govern them, and representing these rules using flow diagrams. This understanding lays the foundation for more advanced algebraic concepts later on.
• Learning Objectives:
• By the end of this week, learners will be able to:
• Identify and extend simple number patterns (both increasing and decreasing) based on a given rule (CAPS: Grade 5 Mathematics Content Area 2 - Patterns, functions and algebra).
• Describe the rule for a number pattern in words (CAPS: Grade 5 Mathematics Content Area 2 - Patterns, functions and algebra).

Lesson notes

2.1 What are Patterns? A pattern is a sequence of numbers, shapes, or objects that follow a specific rule or order. Number patterns are sequences made up of numbers. These patterns can be increasing (getting bigger) or decreasing (getting smaller).

Example: 2, 4, 6, 8, ... is an increasing number pattern.

Example: 15, 12, 9, 6, ... is a decreasing number pattern. 2.2 Identifying the Rule The rule is the key to understanding and extending a pattern. The rule tells us how to get from one number in the pattern to the next. To find the rule, we look for the relationship between consecutive numbers.

Increasing Patterns: Look for addition or multiplication.

Decreasing Patterns: Look for subtraction or division.
