I Organizational moment (Ұйымдастыру кезеңі)

— Good morning students and good morning guests! Welcome to our lesson. Before the starting lesson I want to ask some questions for you. It’s very easy questions not difficult. The first question is What’s the weather like today?

-Ou, good. Excellent.

The second question is What date is it today? –Right you are.

The last question it’s my own question is What ‘s news?

II Review / Quizlet (Еске түсіру стратегиясы)

If you are ready for today’s lesson let’s start our lesson. In order to repeat previous lesson you may open your laptop and you have to do test terminology.

You have to give marks for yourself with these cards. for ex:

- is “Excellent”,

- is “Good”,

- is “Not bad”.

Make a flowchart according to the given sentence

If I teach my subject in English

then I’ll get 35000 tenge for a salary,

else I won’t get.

• What type of algorithm is this flowchart?

• As we know algorithm is devided three types.What are they?

So today’s topic is “Conditional statements IF/ELSE”. The aim of the lesson is

-to apply if statement;

-identify comparison operators;

-apply if/else statements.

At first let’s learn new terms.

Let’s repeat after me today’s new terms.

Open your books and page number 50. First read the text yourself then share in your groups.

Group 1 – subtitle “Condional statements”

Group 2 – subtitle “Comparison operators”

Group 3 – subtitle “If/else statement”

Let’s do two tasks in python for understanding.

For example, suppose you want to find the larger of two numbers. Of course, there is a built-in function max() that does just this (and more) that you could use. But suppose you want to write your own code from scratch.

a=int(input ('Enter number:'))

b=int(input ('Enter number:'))

if a>b:

print ('a')

else:

print ('b')

If temperature outside reaches -30 degrees, school will cancel the lessons. So let us write a code that will check if it is possible to stay home or not.

Int temp=int(input (“What’s temperature today!”))

if temp<=-30:

print (“Tadaaa, stay home and have sweet dreams!”)

else:

print (“Hey,get up !You have lessons today!”)

Practical task

Let’s do practical tasks on computer in a program python.

Practical task

1. Find three errors in the following code:

x = input (“Enter a number:”)

if x=3

print (“You entered 3”)

Answers:

x =int( input (“Enter a number:”))

if x==3:

print (“You entered “ *3)

1. Write a program that defines whether a student has passed the exam or not. Percentage to pass is 50%.

Output: 49 - “fail”

60 – “pass”

Answers:

x=int(input ('Enter number:'))

if x<50:

print ('fail')

else:

print ('pass')

1. Write a program that defines if an input number is positive or negative.

Output: 12, 15, 26 - “positive”

-10, -5, -30 – “negative”

Answers:

x=int(input ('Enter number:'))

if x>0:

print ('positive')

else:

print ('negative')

1. Write a program that defines if an input number is even or odd.

Output: 1, 3, 5, 7, 9 - “even”

2, 4, 6, 8 – “odd”

Answers:

a=int(input('Enter number:'))

if a%2 == 0:

print('odd')

else:

print('even')

1. Write a program that defines if an input human age is retired, adult, teenager or child.

Output: 7 age - “child”

13 age – “teenager”

25 age – “adult”

58 age – “retired”
