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.

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. /BHA

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. > > /BHA |
