* I looked at the Turtle Art program installed in Activity/TurtleArt.activity and determined where I needed to make changes. I had to add a new primitive for square root to the talogo.py file (and also include the sqrt function from the Python math module. And I had to define a new brick for square root in tasetup.py and describe the bricks attributes: its size; how it connects to other bricks; and default values. Finally, I had to create a graphic for the brick (images/en/numbers/sqrt.gif) and modify the panel for numbers (images/en/numbers/numbersgroup,gif and numbersmask.gif). I made similar changes to the Spanish version (images/es).
