Looking For Arrays


If you have an everyday object that is an array, please send it in for our upcoming math unit. Also, I am looking to borrow some mini muffin pans for a center using pom poms to make arrays.


 Thanks
Mary






Work with equal groups of objects to gain foundations for multiplication. 

CCSS.MATH.CONTENT.2.OA.C.3
Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends.
CCSS.MATH.CONTENT.2.OA.C.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.
