Color-coding of quantities? Ok, it's easier to find a box of various
colored chalks, than a collection of different thicknesses of chalk -
but what's the code?!?

This is one of those ideas that sounds better on paper than in the
classroom I think. It's a lot more convenient just to draw the mark
over the symbol than to change chalks. Note--this isn't based on any
analysis of time and motion expended, it's a psychological thing--not
sure I can explain it but try it both ways and see what happens.

If it's chalk, colors didn't erase well enough. And a lot of colors
couldn't be seen from the back of the room even if the board was
black. The arrow above symbol is the best. However,
if the OP has to do something different (than what has worked best
over the years), writing the character twice with the second one offset
will give a "bold" rendition.

I used to carry a full set of whiteboard markers of different colors
with the intent of doing something like this. In practice I used the
black one unless I was drawing a diagram.
