Do Now
1. How many lines of code? 4 6 8 5
2. What is around the word turtle on line 5? ( ; " *
3. Which on is a colon? : ; . <
4. On which lines was the TAB key used?
5. How can you change the shape from turtle to circle in line 5?

First look 👀
Ignore the first lines...
task1() is a function we define
we have to call 📞 task1() to run it 👟
Inside task1()
we create a turtle 🐢 variable called tina
tina has a function called shape() ⬛🔴🔺⬆️🐢
The goto() function
tina has a function called goto() which moves her🏃♀️➡️to given coordinates:
goto(150,50)
goto(100,-100)
goto(-50,50)
def task2():
tina =
tina.shape( )
tina.goto( )

Challenge: move to 3 other coordinates

Topic 2
Turtle Movement
Which function creates a turtle 🐢?
turtle.New() turtle.Turtle() turtle.Start() turtle.Init()
What name did we give to our turtle variable?
toby tarik tess tina
Select the right shape() function ⬛🔴🔺⬆️🐢:
shape(turtle) shape("dvd") shape("turtle") shape(heart)
Challenge: What function moves 🏃♀️➡️ the turtle to the coordinate x=100 and y=100?
Do Now
First look
tina has a function called forward() to move by pixels
tina has a function called left() to move by degrees
Let's finish the square!
Opposite functions!
opposite of forward()?
opposite of left()?
they work the same way!
let's create the opposite_square() function!
triangle()
Complete the code to make the below triangle!
def triangle():
tina = turtle.Turtle()
tina.shape("turtle")
tina.forward( )
tina.left( )

pentagon()
Complete the code to make the below pentagon!
def pentagon():
tina =
tina.shape("turtle")72

Tic Tac Toe Field
penup(): function to stop drawing
pendown() function to start drawing
Complete the field!

goto(100) goto(-50) goto(-50,-150) goto(100,-50,50)
Select a valid 🏃♀️➡️ forward() function:
shape(turtle) shape("dvd") shape("turtle") shape(heart)
