There is nothing more powerful than knowing exactly where your student is developmentally in mathematics so you know how to make strategic goals for your small group or intervention time. If you teach children in the upper elementary grades, it is possible you don't have the primary background to know the phases they children naturally pass through as they acquire an internal understanding of mathematics. Even so, often times those children were just told what to do and if they were not developmentally ready, they may have developed some inefficient compensation strategies, such as using tally marks for adding three digit numbers.
Knowing in which developmental phase your student is working will give you power to make the right instructional decisions to help move him forward in a natural progression, rather than forcing him to perform at a frustrational level.
Students who struggle in math do not progress if they are asked to perform tasks that are above their developmental level.
