Term: 3^rd Term

Week 6
Class: Primary 6
Age: 11 years
Duration: 40 minutes of 5 periods
Date:
Subject: Mathematics
Topic: Everyday Statistics

SPECIFIC OBJECTIVES:
At the end of the lesson, pupils should be able to:

Find the mode from a set of numbers.
Identify the median from a given set of numbers.
Calculate the mean of a given set of numbers.
Solve problems on chances and events.
Solve quantitative aptitude problems related to statistics and probability.

INSTRUCTIONAL TECHNIQUES:

Problem-solving approach
Group activities
Use of teaching aids (charts, data sets, etc.)
Interactive discussions

INSTRUCTIONAL MATERIALS:

Charts with different data sets
Flashcards with statistics formulas
Whiteboard, markers, and erasers
Worksheets for exercises

INSTRUCTIONAL PROCEDURES:

PERIOD 1 and 2:
PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Introduces the concept of statistics and explains mode, median, and mean.	Pupils listen and engage in the discussion.
STEP 2 – EXPLANATION	Explains how to find the mode from a data set using examples.	Pupils take notes and practice identifying the mode from data sets.
STEP 3 - DEMONSTRATION	Demonstrates how to calculate the mode with a set of numbers.	Pupils observe the demonstration and ask questions.
STEP 4 - NOTE TAKING	Explains the definition and method of finding the mode.	Pupils write down the definition and steps.

NOTE (On the Board):

Mode: The number that appears most frequently in a data set.
Example: Mode of 5, 7, 5, 9, 5 is 5.

EVALUATION:

Ask pupils to find the mode from a given data set.

CLASSWORK:

Find the mode from different data sets provided.

ASSIGNMENT:

Find the mode from a set of numbers from the newspaper or a book.

CONCLUSION:
The teacher commends the pupils for their participation and encourages them to keep practicing the identification of mode.

PERIOD 3 and 4:
PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 – INTRODUCTION	Recap the lesson on mode and introduce the concept of median.	Pupils recall the mode and engage in a short discussion.
STEP 2 – EXPLANATION	Demonstrates how to calculate the median from an ordered data set.	Pupils follow along and take notes.
STEP 3 - DEMONSTRATION	Demonstrates the process of finding the median using examples.	Pupils solve examples of finding the median.
STEP 4 - NOTE TAKING	Pupils take notes on how to find the median from a data set.	Pupils write down the steps for calculating the median.

NOTE (On the Board):

Median: The middle number in an ordered data set.
Example: Median of 3, 5, 7, 9, 11 is 7.

EVALUATION:

Ask pupils to calculate the median from a given set of numbers.

CLASSWORK:

Order the data set and calculate the median.

ASSIGNMENT:

Find the median from a data set of 7 numbers in a book or newspaper.

CONCLUSION:
The teacher commends the pupils for their participation and encourages them to practice calculating the median.

PERIOD 5:
PRESENTATION

Step	Teacher’s Activity	Pupil’s Activity
STEP 1 - INTRODUCTION	Introduces the concept of mean and explains how to calculate it from a data set.	Pupils listen and engage in the discussion.
STEP 2 - EXPLANATION	Demonstrates how to calculate the mean from a set of numbers.	Pupils take notes and ask questions for clarification.
STEP 3 - DEMONSTRATION	Demonstrates the formula for calculating the mean: (Sum of all numbers) ÷ (Number of numbers).	Pupils solve examples based on the teacher’s demonstration.
STEP 4 - NOTE TAKING	Explains how to calculate the mean and provides practice examples.	Pupils take notes on the formula for calculating the mean.

NOTE (On the Board):

Mean: The sum of all numbers divided by the total count of numbers.
Formula: Mean = (Sum of all numbers) ÷ (Number of numbers)
Example: Mean of 2, 4, 6, 8, 10 = (2+4+6+8+10) ÷ 5 = 30 ÷ 5 = 6

EVALUATION:

Ask pupils to calculate the mean from given data sets.

CLASSWORK:

Calculate the mean from a set of 5 numbers.

ASSIGNMENT:

Find the mean from 10 numbers in a magazine or newspaper.

CONCLUSION:
The teacher commends the pupils for their active participation and understanding of the concept of mean.

SUMMARY OF LESSON:
This week, pupils will learn about everyday statistics, including the mode, median, and mean. They will practice solving problems related to statistics and probability and apply these concepts to real-life situations.
