Performance objectives

• This week, we dive into the exciting world of patterns! Patterns are all around us in South Africa, from the beautiful geometric designs on Ndebele houses and the intricate beadwork of Zulu artists, to the rhythm of our favourite Gqom song and the way the sun rises and sets each day. In Mathematics, understanding patterns helps us to see order in the world, make predictions, and solve problems. This ability is a foundational skill for all future mathematics, like algebra. By learning to identify and extend patterns, learners develop their logical thinking and problem-solving skills, which are essential for everyday life, such as budgeting pocket money or predicting how long it will take to save for a new toy.
• By the end of this week's lessons, learners will be able to:
• Identify and Describe: Identify and describe the rule for simple number sequences (e.g., counting forwards and backwards in 2s, 3s, 4s, 5s, 10s, 20s, 25s, 50s, 100s).
• Copy and Extend: Copy and extend numeric patterns by applying a given rule.
• Create Patterns: Create their own numeric patterns and describe the rule they used.

Lesson notes

What is a Number Pattern? A number pattern is a list of numbers that follow a certain rule. The rule tells you how to get from one number to the next. Think of it as a secret code!

Types of Number Patterns we will explore: Growing Patterns: The numbers get bigger. This means we are adding the same number each time.

Shrinking Patterns: The numbers get smaller. This means we are subtracting the same number each time. The number that we add or subtract each time is called the rule or the constant difference. How to Find the Rule To become a pattern detective, you need to ask two questions: Are the numbers getting bigger or smaller? If bigger, the rule is addition (+). If smaller, the rule is subtraction (-). By how much are they changing? Find the difference between two numbers that are next to each other. This difference is your rule!
