B5 Mathematics · Term 2 Week 9: Patterns and Relationships

Lesson notes

Learning Objectives

Indicator: B5.2.1.1.5 - Solve a given problem by using a pattern rule to determine subsequent elements

By the end of the lesson, learners can:

Identify the pattern rule in a given sequence by examining the relationship between consecutive elements.
Apply a pattern rule correctly to determine the next three elements in a given sequence.
Solve a real-life problem by using a pattern rule to find subsequent elements.
Justify their solutions by explaining the pattern rule they used, both orally and in writing.
Work collaboratively in pairs or small groups to check and verify each other’s pattern solutions with attention to precision.

E.g. 1. Ask learners to describe the pattern rule for each example and determine the next three elements of each: (i) 1, 10, 7, 70, 67, 670, ... (ii) 10, 12, 16, 22, 30 ... (iii) 50, 48, 47, 45, 44 ...
E.g. 2. Ask learners to describe the pattern rule for each of the patterns and determine the next three elements: (i) .25, .5, .75, ___, ___, ___, (ii) 2.50, 5, 7.50, ___, ___, ___, (iii) 64, 32, 16, , ___, ___, ___, (iv) 900, 450, 225, , ___, ___, ___,
