===1 LEARNING WITH TURTLE ART===
It is very fun to get the turtle doing tricks, but the way you do that is also very similar to the way you program a computer, so when you finish figuring out how to program your turtle, you'll be on your way to learning how to predict what each instruction will cause the turtle to create with line art. It helps you understand the repetition of instructions, and understand following instructions only when a certain condition is met, which is important in computer programming, mathematics, and science.

You program with Turtle Art by snapping together blocks. Each block is a command for the turtle, e.g., there is a block to tell the turtle to go forward, to turn right, etc.

The blocks are organized on palettes: one for the turtle, one for the pen, etc.

Start by clicking on the turtle to show the turtle palette. Try dragging blocks from the palette onto the turtle canvas. Click on them to see what they do...

For example: IF x<30 THEN the turtle will go right ELSE the turtle will go left(We will generate a random number from 0 to 50(x) and then we will check IF this number is <30 .If the statement is true the turtle will go right .But if the number is > 30 our turtle will follow the ELSE and will go to the left).

These blocks are for defining variables and subroutines.

Here we can find the start block which connect the action to toolbar 'Run' button. When we are using this block we only have to push it and the turtle start to compile.

And here is the result of our paint program.

What shape will this set of commands make? Try it and see.

So if all this is clear you can make something new, something creative, something invented by YOU!
