CCSS MATHEMATICS ASSESSMENT TASK ARRAYS GRADE LEVEL 2 MATHEMATICS

Grade Level: 2

Mathematics Domain and Cluster:

Domain: Operations and Algebraic Thinking

Cluster: Work within groups of objects to gain foundation for multiplication

Common Core standard(s) being assessed (if the task is intended to assess only one part of the standard, underline that part of the standard):

2.OA.4 Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends

Student Materials:

• Pencil

Teacher Materials:

• Array assessment sheets

Directions (for teacher to administer assessment task):

Teacher may choose whether to assess students in small groups or as a whole class.

• Hand out Array assessment sheet (one per student)

• Tell students, “For each array, you will need to write a matching equation and show how you added to find the total.”

• Have students work independently on task.

Prompt:

See attachment.

C

5, 10, 15, 20, 25

Answer may look similar to this.

5 + 5 + 5 + 5 + 5 = 25 or 5 + 5 + 5 + 5 + 5 =

10

15

20

25

10

20
