9. CONSOLIDATION/CONCLUSION& HOMEWORK(Suggested time: 5 minutes)
a) Emphasise that:
 Ordering means arranging in ascending or descending order and comparing two or more
fractions means to determine which one is bigger or smaller.
b) The primary purpose of Homework is to give each learner an opportunity to demonstrate mastery
of mathematics skills taught in class. Therefore, Homework should be purposeful and the principle
of ‘Less is more’ is recommended, i.e. give learners few high-quality activities that address variety
of skills than many activities that do not enhance learners’ conceptual understanding.
Carefully select appropriate activities from the Sasol-Inzalo Books, DBE workbooks and/or
textbooks for learners’ homework. The selected activities should address different cognitive levels.

9. REVIEW AND CORRECTION OF HOMEWORK (suggested time: 10 minutes)
Homework provides an opportunity for teachers to track learners’ progress in the mastery of
mathematics concepts and to identify the problematic areas which require immediate
attention. Therefore, it is recommended that you place more focus on addressing errors from
learner responses that may later become misconceptions.

that may later become misconceptions.
35. INTRODUCTION (Suggested time: 10 Minutes)
Activity : Revise with learners the following work done in Grade 6 by asking them to:

define:
 Perimeter of a polygon: The sum of lengths of its sides or the distance along the sides of
a shape.

Define and give examples of the following polygons:
 Regular polygon: A polygon with all angles equal (equiangular) and all sides equal
(equilateral).
 Irregular polygon: A polygon that does not have all sides and all angles equal.
NOTE:
 At this stage learners should apply the definition of a perimeter to determine the perimeter of
both regular and irregular polygons.
 Small lines on the sides of polygons indicate equality.
36. LESSON PRESENTATION/DEVELOPMENT (Suggested time: 20 minutes)
Learning activities
Teaching activities
(Learners are expected to:)
Present the following examples to learners by applying the definition of a be actively engaged during
perimeter to determine the perimeter of a polygon:

answering questions.
Example 1: Calculate the perimeter of polygons:
2 𝑐𝑚
a)
2 𝑐𝑚
Do example 2 as an activity
in their groups and discuss
their solution with the whole
class.
2 𝑐𝑚
2 𝑐𝑚
Perimeter = 2 𝑐𝑚 + 2 𝑐𝑚 + 2 𝑐𝑚 + 2𝑐𝑚 = 8 𝑐𝑚
5 𝑐𝑚
b)
2 𝑐𝑚
2 𝑐𝑚
5 𝑐𝑚
Perimeter = 2 𝑐𝑚 + 5 𝑐𝑚 + 2 𝑐𝑚 + 5 𝑐𝑚
= 14 𝑐𝑚
Example 2: Determine the perimeter of the figure below:
a)
Perimeter = 31 + 42 + 21 + 34 = 128 𝑚𝑚
b)
1,6 𝑐𝑚
1,6 𝑐𝑚
1,6 𝑐𝑚
1,6 𝑐𝑚
Perimeter = 1,6 𝑐𝑚 + 1,6 𝑐𝑚 + 1,6 𝑐𝑚 + 1,6 𝑐𝑚 = 6,4 𝑐𝑚
NOTE: At this stage learners should apply the definition of a
perimeter to determine the perimeter of both regular and
irregular polygons.
37. CLASSWORK (Suggested time: 15 minutes)
Sasol-Inzalo Book 1: page 213 no. 1 (Do shape D, E and F)
38. CONSOLIDATION/CONCLUSION & HOMEWORK (Suggested time: 5 minutes)
a) Emphasise that:
 Perimeter of a polygon is the sum of lengths of its sides or the distance along the sides of a shape.
 Regular polygons are polygons with all angles equal (equiangular) and all sides equal (equilateral)

Irregular polygons are polygons that do not have all angles and all sides equal.
