Lesson 10 — Draw with turtle

Title: Make colorful drawings with Python

Description: Use Python's built-in turtle module to draw lines, squares, stars, and simple art.

Why it matters for kids: Drawing makes code visible. You can see every command become part of a picture.

1. First turtle

Create draw.py:

pythonpython

import turtle

pen = turtle.Turtle()

pen.forward(100)
pen.right(90)
pen.forward(100)

turtle.done()

A small window should open and show the turtle drawing.

2. Draw a square

pythonpython

import turtle

pen = turtle.Turtle()

for side in range(4):
    pen.forward(100)
    pen.right(90)

turtle.done()

The loop repeats the same two drawing steps four times.

3. Add color

pythonpython

import turtle

pen = turtle.Turtle()
pen.color("purple")
pen.pensize(4)

for side in range(4):
    pen.forward(120)
    pen.right(90)

turtle.done()

Try "red", "blue", "green", or "orange".

4. Draw a triangle

pythonpython

import turtle

pen = turtle.Turtle()
pen.color("green")

for side in range(3):
    pen.forward(120)
    pen.left(120)

turtle.done()

5. Easy star

pythonpython

import turtle

pen = turtle.Turtle()
pen.color("gold")

for point in range(5):
    pen.forward(150)
    pen.right(144)

turtle.done()

6. Tiny art project

pythonpython

import turtle

pen = turtle.Turtle()
pen.speed(8)

colors = ["red", "orange", "yellow", "green", "blue", "purple"]

for color in colors:
    pen.color(color)
    pen.forward(100)
    pen.right(60)

turtle.done()
