Small basic lesson 1

• Computing
• Lower Secondary (Key Stage 3)

Do now - What
shape will be
drawn?

Extension

Do now activity should take 3 mins for students to answer after accessing lessonup. 

Extension task allows students to develop their typing skills which will be useful when we move to text based languages. 

Do Now answer

A rectangle will be drawn

Lesson objectives 

Conquer: Understand the concept of a sprite.

 

Aspire Higher: Utilize this understanding to manipulate the turtle sprite. 

 

 

Aspire: Create a set of loops to make a program more efficient.

What is a sprite?

A sprite is an image or set of pixels that can be manipulated using code or code blocks.

• We are going to control a sprite by programming its instructions. 

Block vs Text

• We are used to programming using text based blocks. 
• Now we will become real programmers, now you will be typing instructions for the computer to follow.

Let's test out some code. 3 mins

• Delete the code already there(Click here)

Test these 2 lines of code

• Turtle.move (100)
  
• Turtle.turn (90)
  

Draw a square with these 2 lines of code.

Small basic glossary. 

In a moment we will be doing a drag and drop about what this code does.

Let's test it first! 

Click here

Turtle.move(100)

Turtle.turn(100)

Turtle.TurnRight()

Turtle.TurnLeft()

Turtle.Penup()

Turtle.PenDown()

Test the code

Complete the grid

Moves turtle 100 pixels

Turns turtle by 100 pixels

Stops turtle drawing

Starts turtle  drawing

Turn left 90 degrees

Turn right 90 degrees

Student should test this code - this is a longer activity where students are testing each piece of code in small basic. 

Creating small programs (ISL)

Lets use the lines we just learnt to create some shapes. 

Extension: 

Give the students some time practicing these lines of code, most students should complete shape 1 and 2

What is a sprite?

1. A set of pixels controlled by the user.
2. A non player character
3. An image.
4. The code to move a character.

Which code moves the sprite forward?

1. turtle.move
2. turtle.move(100)
3. turtle.move()
4. move.turtle()

What is the purpose of this line of code?
turtle.penup()

1. Makes the turtle draw.
2. Stops the turtle from drawing
3. Changes the colour of the pen
4. Changes the width of the pen.

What is the purpose of this line of code?

GraphicsWindow.BackgroundColor = "red"

1. Makes the turtle draw.
2. Changes the colour of the pen.
3. Changes the colour of background
4. Changes the width of the pen.

What is the purpose of this line of code?

Turtle.Hide()

1. Hides the turtle from view.
2. Hides the pen from view.
3. Makes the pen ink invisible.
4. Makes the background see through.
