About these Tutorials

The tutorials (called "Scripts 1, 2 & 3") are a teaching activity for my classes.  Until 2010, I taught these lessons at OREC, and now in Fredericton I decided to put these into an official web site with YouTube videos.

I claim no ownership of Scratch.  All of the videos were made by me and you are free to use them in your classroom.  (Free to alter; free to mimic; free of cost.)

If you like these tutorials and/or if you are using them in your classroom, please let me know.

About Scratch

Scratch is a software tool that helps students learn software programming.   This is an entry-level tool (for students who have never programmed before).  It is free and open source software, and was developed by MIT.

What is  " mouse x " ?
What is  " mouse y " ?

Are these  " x " and  " y "  the same directions as your math graphs?     
In other words, if you move your mouse just up and down, what happens?    ... or just side-to-side?
