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/ liketerm.
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.

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 reallife situations with algebra The concept of repeated addition. 
STEP 3 10 mins Activity 2 Group 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(4s2s) = 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.
