Performance objectives

• This week, we delve into the exciting world of numeric patterns and relationships. Patterns are all around us in South Africa – from the repeating designs on shweshwe fabric and the intricate beadwork of Zulu and Ndebele cultures, to the rhythm of our favourite gqom song. In mathematics, understanding patterns helps us to make predictions, solve problems, and understand how numbers relate to each other. This skill is a foundational block for more advanced mathematics like algebra. By becoming 'pattern detectives', learners will develop logical thinking and problem-solving skills that are crucial 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:
• Investigate and extend simple numeric patterns involving a constant difference (addition/subtraction) or a constant ratio (multiplication).
• Describe the rule for a given numeric pattern in their own words (e.g., "I add 5 each time").
• Determine input values, output values, and rules for patterns using flow diagrams.

Lesson notes

What are Numeric Patterns? A numeric pattern is a list of numbers that follow a specific, predictable rule. Our job is to find the rule and use it to continue the pattern or find missing numbers. A. Patterns with a Constant Difference (Adding or Subtracting) This is the most common type of pattern you will see. The rule involves adding or subtracting the same number every time to get to the next number in the sequence.

How to find the rule: Look at the numbers in the sequence. Find the 'jump' or difference between two numbers that are next to each other. Check if this 'jump' is the same for all the other numbers in the pattern.
