These are the math tasks that go along with my Task Rubric (free!). They align with the Common Core Standards for Secondary Math 1.
I use these as a quiz weekly, after I have taught the material. I grade the task in two parts, 1) the computation- did the student answer all parts of the question and get it correct, 2) the essay- was the student able to describe or prove how they got their answer.
