Introduction to Temperature

The degree of hotness or coldness of a body or object is called its Temperature.

To measure temperature we use the thermometer.

There are two main units to measure temperature.
i. the degree Celsius (C)
ii. the degree Fahrenheit (f)

Read temperature on thermometer
To read the temperature, look at the number or mark beside the top of the shaded column.
Note:
When the temperature falls below zero degree Celsius, we use negative number and that means it is getting colder. If the temperature rises and the Celsius is increasing in number from zero, then it is getting warmer.

STARTER
Begin the lesson by showing them a video on temperature.
Pupils should be able to understand temperature and its meaning.

Finding temperature of the water

Get three containers, label the three X,Y and Z
i. pour some cold water from the refrigerator in cup X
ii. pour water from the tap in bowl Y
iii. pour some hot water in bowl Z
iv. note the temperature of each water in terms of hotness, coldness and medium.
v. record your results

STARTER
Start the lesson by asking them questions on which is colder an ice block or cold water? And also a beans stew and hot water which is hotter?

Pupils should be able to:
Guess the temperature of substances whether hot or cold.

Changing units of temperature

There are 100 divisions on the Celsius scale and (212 – 32) = 180 divisions on the Fahrenheit

The boiling point of water is 100 C or 32F.
This shows that 100C corresponds to 18 divisions. Therefore the ratio of the division in Celsius scale to Fahrenheit is 100 to 180

This is written as:
100:180 or 100/180 reducing to lowest term, we have 5:9 or 5/9

This shows that 1C is 9/5 of F and 1F is 5/9C. it also means that one division of the Celsius scale corresponds to 9/5 division of the Fahrenheit scale; one division of the Fahrenheit scale is 5/9 of the Celsius scale. From this, a formula is obtained for changing from Celsius to Fahrenheit scale as follows.

Example
1. change 20C to F
Solution
Using the formula
F = 9/5 C + 32
F = 9/5 x 20 + 32
F = 36 + 32
F = 68
Therefore, 20C is 68F

STARTER
Start the lesson by asking them questions on which is colder an ice – block or cold water? And also a beans stew and hot water which is hotter?

Pupils should be able to
Change or convert units of temperature.

Changing units of temperature.

To change from Celsius to Fahrenheit we use the formula:
F = 9/5 C + 32

To change from Fahrenheit to Celsius we use the formula:
C = 5/9 (F – 32)

Examples
1. Change 86F to C
Solution
Using the formula
C = 5/9 (C – 32)
C = 5/9 (86 - 32)
C = 5/9 x 54 = 30
= 30C
Therefore 86F is 30C

STARTER
Begin the lesson by doing the first example for them.
Pupils should be able to
Calculate and convert C to F and vice versa

### NUMERATION AND NUMBER NOTATION LESSON PLAN AND LESSON NOTE FOR PRIMARY, SECONDARY AND HIGH SCHOOLS

Guide Days Content  Starter  Plenary Class Activities Homework  Monday   Counting and writing whole numbers up to 1000.  Counting and writing numbers in units of thousands.  Writing Numbers in Units of thousands in words.  Resources   Beads, Beans, Number chart, match box  Introduction to numeration and notation  Numeration is defined as the act of counting numbers in words or numerals. Example 1 is one, 2 is two, 10 is ten, 100 is one hundred and 1000 is one thousand while notation is the act or system of using symbols to represent numbers. Example 0,1,2,3,4,5,6,7,8,9 and 10 Counting and writing whole numbers up to 1000 Counting and writing whole numbers up to 1000 will be a lot easier if we classify the numbers into three groups: a. 0 - 9 (these are numbers in units)  b. 10 - 99 (these are numbers in tens)  c. 100 - 999 (these are numbers in hundreds)  Example 1 1. Write 5 consecutive numbers after each of these numbers

### DISCOUNT AND COMMISSION MATHEMATICS LESSON PLAN AND LESSON NOTE FOR PRIMARY AND SECONDARY SCHOOLS

Monday   Meaning of Discount  Finding cost and cash price on discounted goods Resources  Inside out  Learn   mathematics Book 6, page  125  items like; currency note Milo, biscuits, books, pencils, school bag   Meaning of Discount Discount is a reduction in the price of an article. It is often a certain percentage of the actual price of the article. Examples 1. A table clock cost \$200, and a 10% discount is given for paying cash. What is the cash price? Solution The discount = 10% of \$200 =   10     x 200= 20 100 So Cash price = original price – discount                                                             Amount   =    \$200 –  \$20 = \$180  2. The selling price of a shirt is \$900. The trader gives 5% discount for cash. How much is the buyer paying. Solution The discount = 5% of \$900 = \$45 So Cash price = original price – discount amount                         = \$900 – \$45 = \$855 Begin the lesson by showing them an image of a market where buying and selling is taking place, then
