MATHS LAB ACTIVITY • Experiential Learning
Aim: To reinforce the concept of addition and subtraction of fractions with
same denominator on the number line
Materials: Fraction slips, paper and pencil
Instruction for teachers:
Divide the class into the groups of 4–5 students. Make 20 slips of fractions for
each group. Write one fraction on one side of the slip and another fraction with
the same denominator on the other side. Other fraction may have the same or
different colour. If fractions written on the slip are of the same colour, they
will be added and if they are of different colours, they will be subtracted.
Method: First, take two fractions and illustrate how to add and subtract using the
5 2
number line on the blackboard. For example, consider the fractions and .

Step 1: Draw a number line and mark two points 0 and 1. Then, divide the
length between 0 and 1 into 8 equal parts.
