Unplugged Activity | Graph Paper Programming

This lesson is called "Graph Paper Programming"

and it's all about algorithms. Today we're
going to learn how to write programs that

show each other how to recreate simple black
and white images, using only hand drawn arrows.

An algorithm is a list of instructions for
completing a task. We'll follow this set of

instructions to make the bowl. Algorithms
are really helpful when you need someone else

to understand how to do something. If you're
writing an algorithm for a computer, you have

to break it down to little tiny steps. So
finish this row and go to the next, then the

next one, and you'll be done. I use algorithms
in my work. If I write down all of the steps

I can recreate that same piece again, or I
can teach someone else to do it. Put the glass

in the kiln, fuse it together, follow the
rest of the instructions to make the bowl.

Algorithms give you a road map for getting
something done.
