The first picture shows my ESL kiddo's tracker and the progress they made at the end of the year. There were road signs along the road that indicated how much they'd grown, the last one being 1.5 years of growth. As you can see, not everyone met the big goal but everyone grew at least a year and our average was 1.25 years of growth. I'll take it.
The reason why I love this system so much is because of motivation. When students are off task, I redirect them to our tracker and talk about how making poor choices will make them not grow as much. When everyone else is moving up, they want to as well. It can be a little tricky explaining this to first graders, but for the most part I think they understood.
This past year teaching first grade I had an around the world theme and their hot air balloons went up as they grew. This is what our tracker looked like at the end of the year. I love first grade because of the tremendous amount of growth you see! With my super hero theme this year they'll all have a cape and will take off as they grow. : )
