Lesson 3
Topic: Fractions
Subtopic: Addition and Subtraction of Fractions

Materials
•A set of paper strips with words written on it
•Fish bowl

Objectives
•To guess the word written on the paper strip
•To practice patience and understanding to those who can not get the answer correctly

Control of Error
•Teacher

Presentation
•The teacher will introduce the activity and give the instruction on what to do. •She will ask for 5 pairs of volunteers from the class. One volunteer will pick a paper strip from the bowl and the other will guess the word. Then they will exchange places. If they can get the answer correctly, they will receive a prize.

Work by 4’s

Materials
•A set of fraction paper strips
•A box

Objectives
•To add similar and dissimilar fractions
•To participate actively in the activity

Control of Error
•Teacher
•Key cards
Presentation
•The class will form groups of 4 members.
•The group will discuss the steps in adding fractions.
•Each member will get 1 paper strip from the box.
•They will add the fractions on the paper strips.
•Then they will do LAS 1a – 1c.

...Addition and Subtraction of Integers
Addition of Positive Integers
Consider the addition of 2 + 3.
The plus sign, +, tells us to face the positive direction.
So, to evaluate 2 + 3, start at 2, face the positive direction and move 3 units forwards.
This suggests that:
Positive integers can be added like natural numbers.
Addition of Negative Integers
Consider the addition of...
