Second Grade
Mathematics Summative Assessment
In response to North Carolina legislative and State Board requirements, the NC Department of Public
Instruction provides Local Education Agencies with state-developed assessments to be implemented
for Kindergarten, First and Second Grades. These assessments are to include documented, on-going
individualized assessments throughout the year and a summative evaluation at the end of the year.
These assessments monitor achievement of benchmarks in the North Carolina Standard Course of
Study: Common Core State Standards for Mathematics.
The intended purposes of these assessments are:
To provide information about progress of each student for instructional adaptations and early
interventions.
To provide next-year teachers with information about the status of each of their incoming
students.
To inform parents about the status of their children relative to grade-level standards at the end of
the year.
To provide the school and school district information about the achievement status and progress of
groups of students in grades K, 1, and 2.
These state-developed assessment materials are aligned with the Common Core State Standards
for Mathematics and may be adopted or modified as appropriate for individual school districts.
The North Carolina Department of Public Instruction appreciates any suggestions and
feedback, which will help improve upon this resource. Feedback may be sent to NCDPI
Mathematics Consultant, Kitty Rutherford ([email protected]).
INTRODUCTION
The Second Grade Mathematics Summative Assessment is designed to assess student proficiency on
selected standards from the Common Core State Standards for Mathematics at the end of second
grade. The tasks assessed in this document were established based on research and information from
numerous experts, including the Common Core State Standards authors.
The tasks in the student mathematics assessment booklet are designed to mirror tasks and assessment
items that students should be experiencing throughout the year. District leaders have the option to use
the assessment as presented or to adapt the assessment to best meet student needs and district
requirements.
The number of days used to administer the assessment is a District decision or a teacher-based
decision based on each class’ situation. However, the assessment is to be administered at the end of
the school year.
NC DEPARTMENT OF PUBLIC INSTRUCTION SECOND GRADE 2
ASSESSMENT MATERIALS
Each student will need a student booklet and a pencil. Each student will also need access to counters
or cubes throughout the assessment. The counters or cubes can be provided to each student in
individual bags or boxes, or they can be located in a central space from which the children can access
as needed.
ASSESSMENT MATERIALS Included Additional
Student Booklet
Inch Ruler
Pencil
4 crayons (red, blue, yellow, and green)
Calculators are not used during this assessment.
*NOTE: It is possible that printing may have caused graphics to shift. Please check measurement
graphics for accuracy.
ADMINISTERING THE ASSESSMENT
Preparing the students
Because the assessment tasks are similar to the tasks used for daily instruction and on-going formative
assessment, no special preparation for students is necessary. However, teachers may want to explain
to the students that these tasks provide a way to see what each student knows and what each student
still needs to learn. The teacher may also want to explain that the students will need to answer each
question on their own, without support from other classmates or the teacher.
As during daily instruction, students should have a relaxed atmosphere in which to do the tasks. This
assessment is not timed. Students should have as much time as needed, within reason.
Selecting the tasks The tasks can be administered in a sequence that best fits the learning environment. The tasks do not
need to be administered in the order presented. District leaders(s) may decide a particular order for
assessment administration or the decision may be left to the individual teacher. However, some tasks
may have multiple parts that will need to be administered together.
Administration models
The assessment can be administered in several ways. The District Leader(s) may designate a uniform
administration process for all teachers to follow within the LEA/District or the teachers may be asked
to decide on one or more assessment models to use based on their particular students and unique
situations.
NC DEPARTMENT OF PUBLIC INSTRUCTION SECOND GRADE 3
Whole Class: The teacher reads the directions for each task aloud to the entire class ad all
students complete the same items in their student booklet at the same time.
The teacher needs to consider the varying abilities of the students and select items to be
presented in this format that are most likely answered in approximately the same
amount of time. This prevents situations in which students who need additional time to
complete the task are rushed, or students who are ready to move on to the next question
are waiting for other classmates to finish.
Small Group: The teacher reads the directions for each task aloud to a small group of students.
A small group of students complete the same items in their student booklet at the
same time.
This model allows students in the same room to be working on different work at the
same time. Teachers need to read the directions aloud to the students, so it is possible
that some of the students are completing assessment tasks while other students are
working on other classroom tasks and activities. Teachers may decide to set up various
centers/stations of which the students move through, thus completing many of the
assessment tasks after an entire rotation is completed.
Individual: Depending on the students’ needs, the teacher may opt to read the directions for
each task aloud to one student.
This model allows for students who may have been absent from assessment
administration or students who require more one-on-one support for the completion of
the assessment.
The teacher reads aloud all directions and all questions to the students. If a student(s) asks for
clarification, the teacher may reread the directions and questions aloud as often as needed or may
substitute a familiar word for an unfamiliar word (e.g., “number sentence” for “equation”).
However, since the teacher is seeking information about what the student can do independently, the
teacher may not coach or instruct a student on how to answer a question.
Monitoring Students at Work
While students are working in their mathematics assessment booklet, teachers may make notes as needed
about the manner in which students accomplish tasks. For example, a teacher may note if a student uses
counting strategies for simple computation or if the student has an alternative strategy. They may note if
the student works with confidence on all of the tasks or if there some aspects that seem more difficult.
The teacher is encouraged to find out as much as possible about what students are thinking and how
they go about working on tasks. As the teacher circulates, s/he asks the students questions to gain
insight into their understanding and makes notes about students’ responses. For example, the teacher
might say, “Tell me about the picture you have drawn.” or “What else can you tell me?” Discussions
with students offer rich information about students’ understandings.
NC DEPARTMENT OF PUBLIC INSTRUCTION SECOND GRADE 4
If students do not understand a question and ask, “What does this mean?” or say, “I don’t get it.” the
teacher may simply repeat the directions, substitute a familiar word for an unfamiliar word if
necessary, and say, “Do the best you can.”
SCORING THE ASSESSMENT
What does Proficient mean?
When students are proficient with a particular standard/cluster, then they:
can model and explain the concepts,
use the mathematics appropriately & accurately, and
are fluent and comfortable in applying mathematics.
This Summative Assessment is designed to provide additional evidence of students’ independent
work and will be included with other information gathered about the student. This assessment is not
intended to provide a complete picture of a student’s mathematics understandings. When
determining overall student proficiency levels, this assessment should be combined with additional
documentation such as student products, formative assessment tasks, checklists, notes, and other
anecdotal information.
Determining Proficiency in Performance and Understanding
The Summative Assessment is scored using the Proficiency Rubric. As the teacher scores each
student’s booklet, the teacher may record notes and observations for that student on the Student
Summary form. A Class Summary form is provided to gain a global understanding of the class’
proficiency and for assisting with instructional groupings and planning.

understanding for each task or collection of tasks. Page 8-18

conferences for individual students.

Used to compile all students’ proficiency levels with

Page 19
When scoring each student’s response, the teacher needs to pay particular attention to what the student
does and does not understand. Both are equally important in determining the next instructional steps.
In addition, the teacher needs to look beyond whether an item’s answer was correct or incorrect by
looking carefully at the types of mistakes that were made. Some mistakes that children make come
from a lack of information. At other times mistakes reflect a lack of understanding. There is logic
behind students’ answers. The teacher must look for the reasons for the responses and identify any
misconceptions that may exist.
Student Summary
Once the student’s work has been carefully reviewed and the proficiency scores have been determined
using the Proficiency Rubric, the teacher summarizes the student’s strengths and areas of focus for
NC DEPARTMENT OF PUBLIC INSTRUCTION SECOND GRADE 5
each of the domains on the Student Summary form. The information on this form can then be used to
guide instruction, to share with families during conferences, to inform support staff, and to discuss in
Professional Learning Communities.
Proficiency Beyond the Summative Assessment
As stated earlier, the Summative Assessment is one piece of data collected to determine a student’s
mathematics understanding. When determining overall proficiency for a particular standard or cluster,
a variety of evidence is collected. In addition to the collection of evidence, the following Mathematics
Proficiency Levels rubric (page 15) can help solidify to what degree a student has reached overall
proficiency in mathematics.
SUMMARY
This Summative Assessment has been provided to help efforts to conduct on-going assessment of
students. These items and tasks within this assessment are not intended to provide a complete picture
of a student’s mathematics understandings. Combined with additional documentation, teachers will be
able to make inferences about student achievement and support each student’s development as a
competent mathematician.

2.G.3 Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves,
thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths,. Recognize that equal shares
of identical wholes need not have the same shape.
ANSWER
KEY
A-C. Accept any drawings that accurately represent the flag descriptions. The
pieces do not have to be congruent, but the size should be (relatively) equal.
D. Yes, the pieces are equal. Accept explanations that show that students recognize
that equal shares of identical wholes need not have the same shape.
Level I The student incorrectly partitions shapes A-C OR does not correctly identify D as
partitioned into equal pieces
Level II The student correctly partitions shapes A-C and correctly identifies D as partitioned into
equal pieces, but does not provide an explanation that demonstrates understanding of the
concept.
Level III The student correctly partitions shapes A-C, correctly identifies D as partitioned into
equal pieces and gives ample evidence that the concept of equal shares is understood and
generalized.
