About these arrays worksheets

An array is a group of objects in equal rows, like eggs in a carton or chairs in a classroom. In 2nd grade, children use arrays to add the same number again and again: 3 rows of 4 is 4 + 4 + 4 = 12. This repeated addition is the bridge to multiplication in 3rd grade.

These worksheets keep to arrays of up to 5 rows and 5 columns. Children count rows and columns, write the total as a sum of equal addends, add the same array by rows and by columns, draw arrays from words, work with equal groups, and solve short array word problems.

Most pages come as Sheet A and B. Every page has an answer key on page 2, and all pages print in black and white on US Letter or A4.

Standards

  • CCSS.MATH.CONTENT.2.OA.C.4Use 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.

How to use them

  1. Build arrays with counters or snap cubes first. Rows go across, columns go down.
  2. Use Arrays: Rows and Columns, then Arrays and Repeated Addition.
  3. Use Add by Rows and by Columns to show that 3 rows of 5 and 5 columns of 3 have the same total.
  4. Have children draw arrays from words, then try equal groups and the word problems.
  5. Point out arrays at home: muffin tins, window panes, egg cartons.

Teaching tips

  • Rows go across, like rows of seats. Columns go up and down, like columns holding up a roof.
  • Write one addend for each row: 4 rows of 3 is 3 + 3 + 3 + 3.
  • Skip counting helps: 5, 10, 15, 20 for 4 rows of 5.
  • Equal groups and arrays are the same idea. Each row is one group.

Questions teachers and parents ask

What is an array in math?

An array is a set of objects arranged in equal rows and equal columns. 3 rows of 4 dots is an array with 12 dots.

How do arrays help with multiplication?

An array shows equal groups. In 2nd grade children add them (4 + 4 + 4 = 12). In 3rd grade the same array is written as 3 × 4 = 12.

How big are the arrays?

Up to 5 rows and 5 columns, the size 2nd grade standards use.

Are there answer keys?

Yes. Every page has an answer key on page 2. The Draw an Array key shows the finished array.
