B5 Mathematics · Term 2 Week 8: Patterns and Relationships

Lesson notes

Learning Objectives

Indicator: B5.2.1.1.4 - Represent a given pattern visually to verify predictions

In earlier lessons, learners used concrete materials and tables to extend patterns (B5.2.1.1.1, B5.2.1.1.2). By the end of this lesson, building on the skill of predicting subsequent elements (B5.2.1.1.3), learners can:

Build matchstick patterns for triangles and squares up to the 9th pattern using actual matchsticks or drawn diagrams.
Fill in missing entries in a given table by constructing the visual pattern and counting.
Check a predicted number of matchsticks by drawing or building the pattern and comparing the count with the table.
Explain in writing or orally how the visual picture confirms whether a prediction was correct or needs revision.

E.g. 3 Ask learners to write questions based on number or geometric patterns for their friends to find answers to; e.g. how many match sticks will be used for the 9th pattern of squares? How many match sticks will be used for the 8th pattern of squares?
