Getting Started
There are several Turtle Art manuals:
Start by clicking on (or dragging) blocks from the Turtle palette. Use multiple blocks to create drawings; as the turtle moves under your control, colorful lines are drawn.
You add blocks to your program by clicking on or dragging them from the palette to the main area. You can delete a block by dragging it back onto the palette. Click anywhere on a "stack" of blocks to start executing that stack or by clicking in the Rabbit (fast) , Turtle (slow) or Bug (debug) buttons on the Project Toolbar.
The basics
Drawing shapes
Displaying things
Boxes, Stacks and the Heap
(aka variables, subroutines and the stack)
Mathematics
Make pie charts [1]
