Computation Assessment – Grade 6
September 2010
This assessment has been created to support Grade 6 teachers in identifying their students’ computation
skills. In September, all middle school students will take this assessment within the first two weeks of
school. Teachers will use the results to better understand how to individualize their instruction to support
the needs of their students.
This assessment will parallel one more assessment given this year so that you can see how your students
have progressed in enhancing their computation skills throughout the year. Please see the district
assessment schedule to determine when to administer these assessments.
In order to truly assess students’ computational fluency, students should not be allowed to work on the
assessment during a second block of time. Students should not be given access to scrap paper or
calculators. Some questions may be at a higher level than what is expected of students, but this will help
you identify your advanced students in addition to your struggling students. Ask students to attempt
every question.
Teachers should hand score the assessment. While scoring, pay close attention to the methods students
use to solve each problem, such as partial sums or partial products. Identify each student’s strengths and
weaknesses and record them on the provided spreadsheet
Please share these results with your school’s math coach so that they can identify methods of support for
you in your instruction. You may decide to use these results to help you discuss each child’s
mathematical strengths and needs with parents. Reporting of scores to the district math office is not
required.
