In this unit, we did one practical assignment, where the students had to use a graph to estimate the height of the school (not formally evaluated). After going over tons of examples, it seemed that the students weren't completely ready for the final test. The purpose of this assignment was to get them ready. In order to maximize learning, students did the assignment in groups of 2 or 3. I'm sure it would be just as easy to give this out as an individual assignment. Going through the questions as a group helped the students to learn more and learn faster. The downside was that almost all groups were in the level 4 range, which was not representative of all students individual abilities. That being said, the positive results were that students are now much more comfortable moving between equations, tables of values and graphs.
I took advantage of the group work to evaluate students "Collaboration" learning skill. This is the last page of the assignment, under "Behaviours Observed". The students gave me the success criteria they wanted me to evaluate, and we put them into a checklist. At the end, I had students evaluate themselves using the second grid from the top, and to have their teammates evaluate them in the third and fourth grids. Students had to use pencil to fill in their parts. I put my own evaluation in the top grid in highlighter and pen, with a final overall grade. I explained several times that only my evaluation counted for the report card. The rest was just for their own reflection and self-improvement. Their "Collaboration" mark had no impact on their actual math grade.
