By now the kids should be walking around proudly with their chimes in hand. Ask them what they will do with them now. What I've noticed with this project is that NONE are left behind.
This is my gauge for project success... if lots of projects are left behind i know that it is not working and the kids don't like it. Simple!

Here is a marking rubric for the project. If you want to get all fancy its an example of criterion referenced assessment. Nice to know all the years in university are not going completely to waste... :-)
In our district we cannot mark in a subjective way. Projects have to be marked objectively which is really tough in our area. This marking sheet make it easier, hopefully. I also always give students the chance to fix or improve things and re-submit for a better mark. This marking sheet gives the student a clear picture of what the grade looks like. A mark really should NOT be a surprise for a kid.
