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. [2-OA4]

Subject: Mathematics (2)
Title: Roll an Array
Description:

This lesson presents a hands-on partner activity to introduce second graders to making rectangular arrays. Students will use number dice to roll numbers and then build the coordinating array. An equation will be written to show the sum of the equal addends.

This is a College- and Career-Ready Standards showcase lesson plan.

Title: Arrays in the Real World
Description:

Students will be introduced to arrays in this second-grade engagement activity. As students examine real-world examples of arrays, they will use terms such as rows and columns to describe the array. In a whole group discussion, the teacher will use student observations to highlight the different attributes of arrays that make them a useful model for repeated addition.

This activity was created as a result of the ALEX Resource Development Summit.

Subject: Mathematics (2)
Title: Array We Go!
Description:

In this activity, the students will look at concrete representations, followed by pictorial representations of arrays. Students will write equations, using repeated addition, to determine the total number of objects in a rectangular array.   

This activity was created as a result of the ALEX Resource Development Summit.
