Reflection: Unit Exams Elapsed Time Assessment - Section 2: Assessment


I will use the results from this assessment to determine which students need additional practice and reteaching on elapsed time.  During this unit, several of my students were familiar with time, and would count out the elapsed time mentally.  

Although they were able to calculate the elapsed time accurately, they did not always use the number line.  Because of this, I am unable to determine from this assessment if they have a true conceptual understanding of elapsed time. I will be asking these students to complete a performance task with a number line to complete their assessments. The use of a number line is essential because it is used throughout all future grade levels and it is a model that can be used for all mathematical concepts.  Developing the students skill in using number lines will also assist them when taking high stakes testing. This is a critical model in the Common Core Standards, and one that I want them to use accurately.
