HELP......Formative Assessment in Distress

Formative assessment! I need to get better at this. That is the bottom line. I'm teaching everyday, the kids are actively engaged, they are answering questions, talking about the concepts, and correctly finding solutions. It's all good! Then comes the unit assessment.  Can you hear "The Imperial March" from Star Wars.......The results.........I have failed as a teacher. Too many students are not proficient! What the hell!!!! So I will do better. I will use Formative assessment more. I will not let these kids fail!!!

DAMN GRADES ANYWAY!
