If Statements

Today we are going to look at a new programming method called if Statements. 

If statements use variables and information users enter to make decisions. 

If statements

We can program the computer to change how it responds using information we give it.

Here the response we have changes based on the answer to the question "Is it raining?"

Shape drawing program

We are going to create a program that will draw a shape that the user asks for.

Add the code below to small basic.

Copy paste this code then demo after students have completed this slide. 

TextWindow.WriteLine("What is your shape?")

answer = TextWindow.Read()

if answer = "Rectangle" then

    Turtle.Move(100)

    Turtle.Turn(90)

    Turtle.Move(250)

    Turtle.Turn(90)

    Turtle.Move(100)

    Turtle.Turn(90)

    Turtle.Move(250)

    Turtle.Turn(90)

else

    TextWindow.WriteLine("I dont understand what you said?")

EndIf

Shape Drawing Program

1. Shape selected at start of program and added to variable called "Shape".

2. If shape selected is rectangle run code to draw a rectangle.

Must haves

1. Variable name must match.

2. Code in IF statement needs indentation (space).

3. EndIf to show code in IF statement completed.
