Learning Objective

At the end of the topic the students will be able to Find equivalent fraction Find equivalent fraction with denominator 100 To relate Percentage as a special kind of fraction

whose denominator is always 100.

Write five equivalent fractions of given fractions ¼, 3/4, 7/9.

What does century mean? Have you heard the word percentage?

Percentage is simply a special kind of fraction whose denominator is always 100.

We can change any common fraction or decimal fraction into Percentage by finding its equivalent fraction with denominator 100.

We use the symbol % for Percentage. The symbol means <per cent> or upon 100.It

contains all the numerals of 100 but jumbled up.

1/100 is read as 1 percent or 1%

35/100 is read as 35 percent 15/20 can be changed into Percentage by

finding its equivalent fraction i.e 15/20 x 5/5=75/100=75%

Do the given exercise on Percentage and turn the given Percentage into equivalent fraction.

EVALUATION A worksheet on equivalent fraction will be given

to the students to asses their response to the lesson.

Today we have learnt how to change a given fraction into equivalent fraction with denominator 100.

Tomorrow we will learn how to change a decimal fraction into Percentage.

Learning objective

At the end of the topic the students will be able to

Change Percentage as decimal fraction. Change decimal fraction as Percentage. Rank the fraction by level of difficulties.

Write five fraction of 1 decimal place. Write five fractions of 2 decimal place. Turn these decimal fractions common

fractions.

Learning Objective At the end of the topic the students will be able to Find special price Solve the problems involving Percentage.

Make a report.

Can you find out the cost of a toothpaste if its original price is Rs.50 and it is on Sale with 20% off?

Can you tell the reduced price of a shoe if it is on Sale and 50% off on Rs300?

So now work out how to find the special price of given items.

It is very easy to find out the special price of any item

E.g find out 10% of Rs 80 To find out the special price, we first change

Percentage into common fraction 10%=10/100 Then change <of> into < x> and multiply it

by80 i.e 10/100 x 80= 8 Or 10% of Rs 80=Rs 8

The teacher will ask the students to do the exercise from book and assess their response.

The teacher will ask the students to create a sale menu for a restaurant products and write a report on it.

The children will be given activities to assess their response to the lesson.

The given activity will also help the teacher to know weather she has achieved the lesson objective.
