TEACHER'S NAME:   DINESH KUMAR	SCHOOL:  RMB DAV CENTENARY PUBLIC SCHOOL, NAWANSHAHR
SUBJECT:   MATHEMATICS	CLASS                  :   IX  STANDARD BOARD                 :  CBSE
LESSON TOPIC / TITLE:  CHAPTER 15:  PROBABILITY	ESTIMATED DURATION:  This lesson is divided into seven modules and it is completed in ten class meetings.

PRE- REQUISITE KNOWLEDGE:-

Knowledge of statistics (Bar graph, Mean, mode and median) Class 8

TEACHING AIDS:- 

Green Board, Chalk, Duster, Charts, smart board, projector and laptop etc.

METHODOLOGY:- 

Demonstration and Lecture method

LEARNING OBJECTIVES:

• History, Repeated experiments and observed frequency approach to probability. 

• Focus is on empirical probability. (A large amount of time to be devoted to group and to individual activities to motivate the concept; the experiments to be drawn from real – life situations, and from examples used in the chapter on statistics).

• Calculation of probability with the tossing of one coin, two coin and three coin.

• Calculation of probability with one die and two dice.

LEARNING  OUTCOMES:

After studying this lesson students will be able to understand,

• Concept and meaning of probability.
• Difference between the experimental and theoretical probability.
• Possible outcomes and favorable outcomes.
• All terms related with the tossing of coins.
• All terms related to the tossing of dice.
• All terms related to the tossing of playing cards.

KEY TERMS :

Probability, Possible outcomes, Favourable outcomes, sure event, certain event, impossible event, equally likely events, coin, dice, playing cards etc.

PROCEDURE  & EXPLANATION

COMPLETE EXPLANTION

Teacher will ask the class about the probabilities and its related terms like possible outcomes and favorable outcomes. Teacher may explain different situations to the students so that students start understanding the meaning of probability. When the class starts giving some responses then teacher will introduce the topic probability step by step as follows.

 Introduction and Warm-up Session

Begin the session by recalling the concepts learnt by students in the previous class. Teacher may ask questions regarding terms, such as experiment, trial, event and outcome. Teacher may also give some questions where the students have to calculate the probability of an event. Thereafter, explain the concept of theoretical probability.

Classical Definition of Probability
Teacher will take some examples from the surroundings and relate the different situations with the concept of probability and introduce the classical definition of probability.



Possible outcomes: Total number of situations which are in the favor or against of an event.
Favorable outcomes: Total number of situations which are in favor of an event.

Total Probability of an event
Now teacher will explain to the students that sum of all probabilities related to an event is always equal to one
   P(E) + P(not E) =1
Where P(E) denotes the probabilities in favor of an event and P(not E) denotes the probabilities which are against the given event.

Activity 1

In this activity, students will perform an experiment to understand the difference between experimental probability and theoretical probability.

Divide the class into a few groups and ask them to perform an experiment as follows. Give three coins to each group and ask them to find the experimental probability of getting  two heads. The students should record the outcomes of their experiment in a sheet. Then, ask the students to check the outcome of the experiment using theoretical probability. Guide the students in the right direction by asking them about the possible outcomes. Once the activity is done, discuss the difference between the experimental and theoretical probability. 

In this activity, students will perform experiments and explain various concepts, such as equally likely outcomes, elementary event, complement of an event, sure event and impossible event.

Activity 2

Divide the class into three groups. The groups have to use different examples to explain the concepts. They can use charts or show experiments in the class. After the presentation, give the students questions (word problems) pertaining to the concepts of probability.

Supplemental Activities

Ask the students to perform the following activity:

Select the 100 students of different age groups and survey about  the different diseases  they have faced in a given year. Then present the findings in a tabular form and calculate the probability of the most common disease for the children of different age groups.

Find out about the role of probability in a cricket match. For example, the toss of a coin between the captains to decide which team would bat/ball first.

Find out how probability is used in various occupations, such as healthcare insurance, advertising, farming and weather forecasting. Share your findings with the class.

Tossing of coin

Now teacher will explain the concept of probability with one coin, two coins and with three coins. Students will be given different situations so that the understand the concept clearly

One coin - Possible outcomes = 2

Two coins - Possible outcomes = 4

Three coins - Possible outcomes = 8

Tossing of Dice

Now teacher will explain the concept of probability with one die and with two dice . Students will be given different situations so that the understand the concept clearly

One die - Possible outcomes = 6

Two dice - Possible outcomes = 36

Playing Cards
Now teacher will explain the concept of playing cards and and will provide different problems to the students so that they will learn the concept in detail.

Total Playing cards = 52
No. of face cards = 12
No. of ace cards = 4
No. of king cards = 4
No. of Queen cards = 4
No. of Jack cards = 4

STUDENTS DELIVERABLES:-

• Review questions assigned by the teacher.
• Solve N.C.E.R.T problems with examples.
• Students can also prepare a Power Point Presentation showing the concept of playing cards / tossing of coins / tossing of dice
• Students can solve the assignment on Probability given by the teacher

EXTENDED LEARNING:-

Students can extend their learning by studying basic concepts and formulas of mathematics through the Resource Centre Mathematics and can find interesting topics on mathematics at the site https://www.cbsemathematics.com/

ASSESSMENT TECHNIQUES :-

Assignment sheet will be given as home work at the end of the topic. Separate sheets which will include questions of logical thinking and Higher order thinking skills will be given to the above average students.
Class Test, Oral Test, worksheet and Assignments. can be made the part of assessment. Re-test(s) will be conducted on the basis of the performance of the students in the test.
