Making Arrays WORKSHEET
Suitable for Grades: 2nd Grade, 3rd Grade
CCSS: 2.OA.C.4, 3.OA.A.1
CCSS Description: Use addition to find the total number of objects arranged in rectangular arrays with up to five rows and up to five columns; write an equation to express the total as a sum of equal addends.
Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7

Making Arrays WORKSHEET DESCRIPTION
Introduce students to arrays with this worksheet. At this stage, arrays are used to represent repeated addition as multiplication is introduced.
In section A students are presented with various repeated addition problems and they will choose from pairs of arrays, the array that correctly matches each problem.
Next students will draw arrays to match given number sentences, helping them visualise the concept of repeated addition in a more interactive way.
Lastly, in section C learners are shown different arrays and must write the corresponding repeated addition number sentence for each one. This allows learners to begin to see how different addition statements can be written about the same arrays.
