๐ŸŽฏ Learning Goals

By the end of this lesson, you'll be able to:

  • โ—‹ Can combine straight lines and rotations
  • โ—‹ Can draw the 'ใ„ฑ' shape
  • โ—‹ Understands that code order matters

โšก 30-Second Challenge

Run the code below to see the 'ใ„ฑ' shape!

Did it work? Let's learn more about it below!

Core Concepts

Analyzing the 'ใ„ฑ' shape

'ใ„ฑ' is made up of two lines:

Order Action Result
1๏ธโƒฃ Move forward Horizontal line
2๏ธโƒฃ Turn right 90 degrees Change direction
3๏ธโƒฃ Move forward Vertical line

Order matters!

Watch the order!

If you rotate first, you get a different shape!

  • Move โ†’ turn โ†’ move = ใ„ฑ shape โœ…
  • Rotate โ†’ move โ†’ move = ใ…ฃ shape โŒ

๐ŸŽฏ Mission
โ—‹ Try drawing the 'ใ„ฑ' shape! (forward โ†’ right 90 degrees โ†’ forward) 
# Add blocks and the Python code will show up here...
Add blocks and the flowchart will show up here...
100 90 90 100 







Example Code


import turtle
t = turtle.Turtle()
t.shape("turtle")
t.forward(100)   # Horizontal line
t.right(90)      # Going downward
t.forward(100)   # Vertical line





What Happens


The 'ใ„ฑ' shape gets drawn!






Quiz



    
Quiz: the order for the 'ใ„ฑ' shape

    

        Which order is correct to draw the 'ใ„ฑ' shape?
    

    

        
        
        
    

    






Show Answer

Answer: B) Move โ†’ turn โ†’ move


First draw the horizontal line, change direction, then draw the vertical line.

Problem: a different shape shows up instead of 'ใ„ฑ'!




โŒ Wrong order


t.right(90)      # If you turn first...
t.forward(100)   # Move down
t.forward(100)   # Keep going down (ใ…ฃ shape)


Cause: the rotation angle or direction is wrong






โœ… Correct order


t.forward(100)   # Go right first
t.right(90)      # Then turn
t.forward(100)   # Downward (ใ„ฑ Shape)


Fix: right(90)Use it, and check the order!






Try Coding It Yourself


Take what you learned with the blocks and write it yourself in Python code!


Drawing the ใ„ฑ Shape


forward()and right()Draw the 'ใ„ฑ' shape with it.








Example Answer

import turtle
t = turtle.Turtle()
t.shape('turtle')

t.forward(100)
t.right(90)
t.forward(100)



Result: The turtle draws the 'ใ„ฑ' shape!








ใ„ฑ Shape Practice


    

  • Order: move โ†’ Rotate โ†’ move
    • 

  • Rotation function: t.right(90)
    • 

  • Number of lines: 2(horizontal + vertical)
    • 







Review Checklist


    

  • [ ] You can describe the order for drawing the 'ใ„ฑ' shape (move โ†’ turn โ†’ move)
    • 

  • [ ] You know why you use right(90) for the 'ใ„ฑ' shape
    • 

  • [ ] You understand that changing the order of the code makes a different shape
    •
