So, here's what we did (yes, in late February)... We created a SCORE BOARD (ahem ... rubric)!
Here is what it looks at. I have been giving a new goal everyday! They are to score at least a certain amount of points per writing! If they meet it, there is a reward! Then I "up the anty" every week by 10 points! We are now up to getting 50 points on each of our writings! It seems to be working. Here is what the score board looks like! Enjoy!
