Use the command center to create a turtle
First define its shape
Next create one turtle
5
Now give commands to the turtle
Set to T for turtle
Give the command pd for pen down
6
Begin to draw a box using the commands fd
(forward) and lt (left turn)
7
Make your algorithm into a procedure
Commands to create the turtle in a
procedure called setup
Commands given to the turtle in a procedure
called go
8
Create 2 buttons to run your proceduresUse the
button icon on the interface toolbar.
Runs the setup procedure
9
Try out your new buttons
