Generally the purpose of classroom computation isn’t quantity, it is quality with a focus on explaining the strategies used and how/why it is true. However, the purpose of targeted skills practice includes fluency, as well as additional review to build comprehension. I am looking for the student to demonstrate their fluency on this skill by completing the assessment with very few errors and within a reasonable amount of time. The assessment is meant to be completed in approximately 15 minutes.
