The Turtle's Pen
The turtle carries an invisible pen. By default, the pen is down — meaning whenever the turtle moves, it draws a line behind it on the canvas.
- ✏ Pen Down — puts the pen on the canvas so the turtle draws as it moves
- ✋ Pen Up — lifts the pen so the turtle moves without drawing
💡
Pen is Down by Default
The turtle always starts with the pen down. Add Pen Up at the start if you want to move to a starting position without drawing.
Drawing a Square
A square has 4 equal sides and 4 right-angle corners. To draw one:
- Move Forward 80 → Turn Right 90°
- Move Forward 80 → Turn Right 90°
- Move Forward 80 → Turn Right 90°
- Move Forward 80 → Turn Right 90°
That is 8 blocks for one square. Notice the pattern? In Lesson 5 you will learn to do this in 2 blocks using a loop!

The 360° Rule
A square has 4 corners, each turning 90°. Total = 4 × 90° = 360°. Every closed shape you draw will always total exactly 360° of turning — that's a real geometry rule!
