Try Turtle Art
What shape will this set of commands make? Try it and see.
Drag each puzzle piece onto the turtle's floor. Next, click the bar next to the piece, then type numbers to enter the number values you see, such as color and shade. Once all the pieces are locked together, click the first puzzle piece to start your turtle.
Did your turtle draw this shape?
If your turtle didn't draw the shape of an uppercase A, or if the color is different, check each puzzle piece one at a time, pretending that you are the turtle trying to understand the command you gave it. When you see a number or a piece that is out of place, change it and try again.
