STUDENT NUMBER: 201900309
SUBJECT:
GRADE: 7
MATHEMATICS
Lesson topic: EXPONENTS
1. Situation analysis of the classroom context
Develop positive relationships and attitudes with other peers. Engage learners and share their
knowledge. Develop skills, understandings and attitudes. Develop team work skills. Reflect on their
individual experiences
2. Draw a X over the intended aim(s) for your lesson:
(a)identify and solve
problems
(d)work
effectively
as
individuals and with others
as members of a team
(b)engage in critical and
creative thinking
(e)collect, analyse, organise and
critically evaluate information
(c)communicate effectively
using visual, symbolic
and/or
language skills in various
modes
(f)science and technology effectively
and critically showing responsibility
towards the environment and the
health of others
g)demonstrate an
understanding of the world as a
set of related systems
3. Indicate the specific aims for your subject as it relates to your lesson:
The only specific aim for this lesson is for the learners to understand the laws of
exponents
4. Objective(s) for the lesson:
-
At the end of the lesson, the learners will be able to demonstrate how to solve
expressions which consists of laws
-
The learners will be able to understand the laws of exponents
5. Teaching strategy: Direct teaching strategy
The learners will be given the introduction of the topic, I will write down the important
notes that the learners will need. The learners will be given examples from the
examples, the learners will give or say their understanding of the topic or content. The
learners will elaborate what they understand and then they will be given the activities
to work independently with their peers
6. Introduction to the lesson:
A good understanding of the Laws of Exponents is the key to being good at Algebra which forms
the basis of all High School mathematics. Exponents and powers are ways used to represent very
large numbers or very small numbers in a simplified manner. For example, if we have to show 3 x 3
x 3 x 3 in a simple way, then we can write it as 34 , where 4 is the exponent and 3 is the base. The
whole expression 34 is said to be power.
7. Body:
Learning content (See the
CAPS)
Sequencing of content
Learning activities (List the
activities learners will be
engaged in) and pacing
1) What are
exponents and
powers
2) Exponential
notation
Exponents and powers involve
repeated multiplication.
Complete the following work
Exponential notation provides an
1. 𝑎2 × 𝑎
efficient mathematical notation for
2. 2𝑦 × 4𝑦2
describing repeated multiplication.
3. 2𝑦2÷2y
Exponential laws provide shortcuts
4. (𝑥2 ÷ 2𝑦)
for working with powers and
5. 𝑎2 × 𝑎
exponents. Exponential growth
6. 7𝑎0 × 𝑎
describes the growth of things that
change by doubling, tripling,
halving, etc. like compound interest
and the growth of bacteria.
Look at these 2 examples: 2 × 2 × 2
×2×23×3×3×3×3×3×3×3×
3 × 3 × 3 × 3 × 3 × 3 × 3 Do you see
that it is difficult to read an
expression where a number is
multiplied by itself many times? It
also takes up a lot of space. To deal
with both problems,
mathematicians invented
exponential notation.
Exponential notation involves a
base and an exponent. There are
two examples alongside. In the first
example, the base is 2 and the
exponent is 5. In the second
example, the base is 3 and the
exponent is 15. We write the
exponent as a superscript. The base
and exponent together form a
power. We say “2 to the power of
5” or “2 to the exponent 5” or “2 to
the 5” which means we are
multiplying 2 by itself 5 times and
we say “3 to the power of 15” or “3
to the exponent 15” or “3 to the 15”
which means we are
multiplying 3 by itself 15 times
According to the definition, we can
use any value as a base, except 0.
Bases can be natural numbers,
3) What kinds of
numbers can we use integers and even fractions. Here
are some examples:
for bases?
𝟐,
𝟏
(𝟑)𝟐
, (𝟐𝒙)
𝟐
4) The laws of
exponents
If we multiply the power of the
same bases,
(𝟑)𝟐 × (𝟑)𝟐 = 𝟑𝟐+𝟐 = (𝟑)𝟒
we add the exponents.
If we divide powers of the same, we
subtract the exponents.
(𝟑)𝟐 ÷ 𝟑 = 𝟑𝟐−𝟏 = 𝟑

Include the questions that you will ask during the lesson to formatively assess learners:
1. Represent the following in simplest exponential form:
a) 3x3x3x3x3x3x3
b) a x a x a x a x a x b x b x c
c) c x c x c x m x m x m x p 2. Simplify the following
a) 𝒂𝟐 x a x a x 𝒎𝟐x 𝒎𝟐
b) 𝟐𝒎𝟐 x 𝒎𝟐
9. Alignment
•
What should learners be able to demonstrate at the end of a learning experience?
How the laws of exponents work when we solve an exponential expression
•
Which most suitable teaching and learning activities will enable learner engagement to attain
the learning objectives?
The learners will work in pairs
I will bring media that will benefit the teaching and learning
The learners will work in group
•
How will the successful attainment of the learning objectives be determined
The successful attainment will be determined when I can observe that the learners master, knows
how to demonstrate the work and understands the content
10.
Teacher-learner participation
Plot (“X”) and motivate the teacher-learner participation as you envisaged in your planning of the
lesson on the continuum below.
The lesson is learner centred, as throughout the lesson I will be asking questions and learners will be
expected to answer and give solutions to question. And I will be facilitating the lesson. The learners
will have the chance to ask, share or put inputs of their view in class.
Teacher- centred

Conclusion of the lesson
Exponents are the way to understand the algebraic expression for the grade and higher grades. The
laws of exponents play a very important role on algebraic expressions. Simplifying, factorise and
expansions, they are based from the laws of exponents.
