STEPS TEACHER’S STUDENT’S LEARNING POINT
ACTIVITIES ACTIVITIES
Introduction The teacher asks the They all answer the to review pre-requisite
students to solve 15 = p – questions knowledge
3
Presentation The teacher explains They all listen To know the meaning
Step 1 algebraic expression and attentively of algebraic expression
coefficient and coefficient
ALGEBRA
EXPRESSION
It is a statement that
uses letters for numbers
COEFFICIENT
It is a number
multiplying an algebraic
letter.
Steps 2 The teacher solve They all listen To know how to solve
problems involving attentively to the problems involving
negative and positive teacher positive and negative
terms of algebraic terms of algebraic
expression using the expression
below examples
Example
Simplify 2a + 3s
2a + 3a
= 5a
Simplify 7y – 4y
7y – 4y
= 3y
Simplify 3a – 8a + 5a + 9a
– 2a
SOLUTION
Put all the positive
numbers together and also
the negative numbers.
3a – 8a + 5a + 9a – 2a
3a + 5a + 9a – 8a – 2a
17a – 10a
= 7a
Step 3 The teacher works our They all listen To know how to solve
more problems involving problems involving
negative and positive positive and negative
terms of algebraic terms of algebraic
expression using the expression
below examples
Examples
7h – 4 – 3h +11
Collect like terms
7h – 3h +11 – 4
4h + 7
Simplify 8x – 6y 9y – 2x
Collect like terms
8x – 6y – 9y – 2x
8x – 2x – 6y – 9y
6x – 15y
Evaluation The teacher gives students They all write to do To get Feedback from
work to do in the class the work the students
Class work
20x – 2x
11e + 8e
12d – 5d – 3d + 4d
7m + 3 + 2m + 1
Conclusion The teacher writes the They all write if To ensure learning
correction on the board need be objectives are met
Assignment The teacher givers work to They all write Learning extend
do at home to the home
Assignment
Simplify the following
