**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.
**Standard(s): **

[MA2015] (2) 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)
