B6 Mathematics · Term 2 Week 9: Pattern and Relationships

Lesson notes

Learning Objectives

Indicator: B6.2.1.1.4 - Represent a given pattern visually to verify predictions

By the end of the lesson, learners can:

Draw the next two terms of a given matchstick pattern to check whether their numerical prediction is correct.
Create a visual representation (diagram or drawing) of a matchstick pattern from a table of values.
Verify a stated prediction by drawing the pattern and counting the matchsticks.
Use visual representations to justify whether a predicted number of matchsticks for a given pattern number is correct or incorrect.
Construct their own matchstick pattern, draw it, and use the drawing to make and verify a prediction.

Exemplars (from the NaCCA curriculum)

E.g. 1. Ask learners to examine the pattern made with match sticks below

E.g. 2. Ask learners to examine the pattern in the table below which shows the number of match sticks used in making a pattern of squares. Pattern Number 1 2 3 4 5 6 7 8 9 Match sticks in the

in the pattern Ask learners to use match sticks to make the patterns of triangles and complete the table. Guide learners to describe the relationship

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 triangles? How many match sticks will be used for the 8th pattern of squares? Number of triangles 1 2 3 4 5 6 7 8 9 Match sticks 7 12 This is the first algebra indicator in B6 and the document numbers it .4: there is no B6.2.1.1.1, .2 or .3. The two match-stick tables are set below the exemplars and their cells interleave with them in the text layer; the figures show them.
