This is part four of a series of posts on writing in math class using mathematical proficiency as a framework. Please be sure to see the other 3 posts.

**Adaptive Reasoning: **

*In these types of prompts, students are really trying to communicate their mathematical thinking. They are trying to communicate their understanding, defend their ideas, and map out their ways of knowing. *

These prompts really tap into depth of understanding. Students,, as well as teachers, can find out for themselves if they really know a particular concept. Is it possible to choose prompts for students depending upon their competency level or should the same prompt be given to the entire class?
