Mathematics ASEI Lesson Plan
Subject: Mathematics
Theme: Algebraic processes
Topic: Algebra
Sub Topic: Removing brackets involving one variable
Date: dd/mm/yyyy
Class: Basic 6
Duration: 35 Minutes
No of Learners: 30
Learning Objectives:
By the end of the lesson learners should be able to:Remove the brackets of algebraic expressions involving one variable/ like-term.
Simplify the algebraic expression.
Rationale:
In our daily life, we encounter situations where we buy the same type of items from different shops and put them together. Also,we come across expressions involving quantities such as 2 chairs, 5 tables, etc. Algebra is that branch of mathematics that uses letters in place of numbers.
Prerequisite/ Previous knowledge:
Pupils have learnt about- Addition, Subtraction and multiplication of variables.
- Like and unlike terms
- Understanding the definition of a variable - understanding what is meant by bracket
Learning Materials:
Bananas, Apples, Mangoes, straws, bottle covers
Reference Materials:
National Mathematics Centre Teaching Module for Primary School Six.
Lesson Development:
| STAGE | TEACHER'S ACTIVITY | LEARNER'S ACTIVITY | LEARNING POINTS |
|---|---|---|---|
| INTRODUCTION full class session (5 mins) | Recap of previous lesson E.g. Simplify the following:
| Pupils respond to the teacher's question.
| Addition and subtraction of like terms. |
| STEP 1 2 mins. | The teacher gives the pupils instructions by asking them to arrange themselves into groups. | Pupils respond to teachers instructions by grouping themselves and choose their leaders and secretary. | Developing leadership skills. |
|

| STEP 2 DEVELOPMENT 5 mins. Activity 1 Whole Class | Find out from pupils in each group how many of them like these particular types of fruits; mangoes(m), apples(a), bananas(b). Teacher captures response for each group and teacher guides pupils to understand practically that, suppose m represents the mangoes, a represents the apples and b represents the bananas.
| Identifying the learning materials for teaching; Bananas, Apples, Mangoes, straws, bottle covers. | Linking real-life situations with algebra The concept of repeated addition. |
| STEP 3 10 mins Activity 2Group Work | The teacher gives 20 straws to each group. Ask 4 members of each group to pick 2 straws. | 4(2s) | Removing brackets and simplifying |
| Ask them to count the number of straws they picked. Let pupils compare their results | 2s + 2s +2s + 2s = 8s | ||
| Ask 3 members in each group to pick 2 straws and 3 straws in their left and right hands respectively. | 3(2s + 3s) | ||
| Ask pupils to count the number of straws in each group and compare the results | 3((2 + 3)s) = 3(5)s = 15s | ||
| Ask 5 members in each group to pick 4 straws each. | 5(4s) | ||
| Ask each of them to take away 2 straws and count the number of straws left | 5(4s-2s) = 5((4 - 2)s) = 5(2)s = 10s | ||
| Ask 2 members in each group to pick 5 straws and 3 straws. | 2(5s + 3s) | ||
| Ask each of them to take away 4 straws and count the number left. Ask the same pupils to take away 1 straw and count the number of straws left. |

| EVALUATION 7mins | Simplify the following:
| Pupils responds to teachers questions
| Asking the learners questions to assess the achievement of the set objectives. |
|
| |||
| CONCLUSION 3mins | The teacher asks the pupils to simplify the following.
| The pupils respond to the teacher's question.
| Acquiring/ improving understanding of algebraic expressions. |
| ASSIGNMENT | Give them other problems to solve.
| Pupils solve other problems. | Improving their level of understanding. |
