In this assessment task, students us a band representation to show different way students can be organized in an array.

In this assessment, students use a flower representation to create arrays and write equations.

This is the About the Cluster document written by the NC2ML group who created the instructional frameworks. This is a great resource to read while starting to plan for Second Grade Cluster 3.

This video resource is useful in helping students to understand how to partition a rectangle by using rows and columns. The video is the second one on the page.

This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Math.

Students roll a die to determine the number of rows for the array and roll the die a second time to determine the number of counters to put in each row of the array. Next, students draw the array and write an equation to express the total number of counters as a sum of equal addends.

This file contains sample anchor charts to create with students. Anchor charts are to be made with students, then displayed as a classroom reference. Parents may also benefit from seeing anchor charts, as they provide a snapshot into the math class.

This assessment may be used for instructional or assessment purposes. A scoring rubric is included.

In this lesson, students create arrays to solve a problem within a real-life context and write repeated addition equations that represent the arrays they have created.

A Common Formative Assessment (CFA) provides a snapshot of current student understanding. It serves as a checkpoint, and may be used to guide future whole and small group instruction. This CFA addresses 2nd grade, Cluster 3 standards.

This resource is part of Tools4NCTeachers. The Family Letter is intended to be sent home at the beginning of Cluster 3. It explains big ideas of the cluster using family-friendly language. Families can also find tips for working with their children at home, digital games, videos, and books. This file contains both English and Spanish versions of the Cluster 3 Family Letter.

The intended purpose of this document is to provide teachers with a tool to determine student understanding and suggest instructional moves that may help guide a student forward in their learning. It is not an exhaustive list of strategies.

In this lesson, students explore ways to design trays that will fit different amounts of cookies in order to develop their understanding of arrays and repeated addition.

In this lesson, the students are analyzing arrangements of shapes and identifying whether or not they are arranged in an array. This lesson needs to be after the students have already learned the vocabulary associated with arrays and have worked with arrays.

This is lesson three in a series of six lessons focused around developing a mathematical community at the beginning of the school year. While this lesson addresses standards NC.2.OA.2 and NC.2.NBT.4, the primary goal is for students to recognize that mathematicians listen to and learn from one another.

This resource is from Tools4NCTeachers.  In this lesson students explore arrays through the context of flats of flowers.  Students determine the total number of flowers and write an equation using equal addends.  Students calculate the total cost of flats of flowers within 99¢ and represent cost with variations of quarters, dimes, nickels, and pennies.

In this lesson, students use square tiles to create rectangles using the vocabulary rows and columns. They write an equation to represent the total.
