My students have worked in "recorder groups" for a few years now. I created this chart to track each group's goal and the average of their playing test grades.
I paste a copy of the goal chart up on the Smartboard for a student to fill in. Each group discusses what they want their average test score to equal for the first column. The 2nd column is for them to post their actual average.
Test scores this past year went through the roof for EVERY child.
Included in this are 4 different charts (in PDF form) : 2 in "color" and 2 in b/w. One set is for a class with four groups and the other set is for a class with five groups.
