I had to click on it to see the graphic.

I am not saying what you have doesn't have value. In fact, the opposite.
However, it's my personal opinion that the output is not readable by a
student at the level we are discussing (which is very very low). I
could be wrong. Just my 2 cents.
Another idea: Why not break the 20 or so steps to solve a problem down
to questions? Each step would be presented, follow by "Is this
correct? (Y/N)" Occasionally, present a wrong step (eg, subtracting a
3 instead of a 4). If they answer incorrectly, just put them back on
the right path. If they answer correctly, give them a point or a star
or something.
