Key takeaway: Our grade 2 arrays worksheet gives second graders 24 problems on counting rows and columns, writing repeated addition equations and finding totals. A free answer key is included.
Early problems use dot pictures. Later ones ask children to draw an array, find a missing number of rows and correct a mistake.
This worksheet gives 24 problems on arrays with up to 5 rows and 5 columns. Students count rows and columns, write repeated addition equations, and find totals. Each problem lines up with Common Core standard 2.OA.C.4.
The first problems use pictures. The last problems are word problems with more than one step. Write an equation for each array.
Grade 2 Arrays Worksheet: problems 1–5
1. Count rows and columns
How many rows are in the array? How many columns are in the array?
2. Rows and columns again
How many rows are in the array? How many columns? How many dots are in each row?
3. Add the rows
Write an equation that adds the rows. Then find the total number of dots.
4. Add the columns
Write an equation that adds the columns. Then find the total number of dots.
5. Two rows of three
Write an equation to find the total number of stars in the array.
Grade 2 Arrays Worksheet: problems 6–10
6. Five rows of two
Write an equation that adds the rows. Find the total.
7. Finish the addition
An array has 4 rows. Each row has 5 stars. Find the sum: \(5+5+5+5=?\)
8. Four by four
Write an equation that adds the rows. How many squares are in the array?
9. Muffin tin
A muffin tin has 3 rows with 2 muffins in each row. Write an equation and find the total number of muffins.
10. Window panes
A window has 4 rows of glass panes. Each row has 3 panes. Write an equation and find the total number of panes.
Grade 2 Arrays Worksheet: problems 11–15
11. Draw an array
Draw an array with 3 rows and 5 columns. Write an equation that adds the rows and find the total.
12. Seats in a van
A van has 5 rows of seats. Each row has 2 seats. How many seats are in the van? Write an equation.
13. Same total
Write an equation for each array. Do the arrays have the same total?
14. Sticker rows
Maya puts 4 rows of stickers on a page. Each row has 5 stickers. How many stickers are on the page?
15. How many rows?
Jamal writes \(3+3+3+3+3=15\) for an array. How many rows does his array have? How many objects are in each row?
Grade 2 Arrays Worksheet: problems 16–20
16. How many in each row?
An array has 4 equal rows and 12 dots in all. How many dots are in each row? Write an equation to show it.
17. Doubles
An array has 2 rows with 4 dots in each row. Write a doubles equation and find the total.
18. Sticker sheet
A sticker sheet has 5 rows and 5 columns of stickers. Write an equation that adds the rows. How many stickers are on the sheet?
19. Garden rows
Priya plants tomatoes in 4 rows. She puts 5 plants in each row. How many tomato plants does she plant? Draw the array and write an equation.
20. Theater seats
A small theater has 3 rows with 5 seats in each row. Six seats are taken. How many seats are empty?
Grade 2 Arrays Worksheet: problems 21–24
21. Two cookie trays
Tray 1 has 3 rows of 4 cookies. Tray 2 has 2 rows of 4 cookies. How many cookies are on both trays?
22. Find the mistake
Diego has an array with 4 rows of 5 dots. He writes \(5+5+5=15\). What mistake did Diego make? Write the correct equation.
23. Rows and columns both
Ethan’s photo wall has 4 rows with 5 photos in each row. Write one equation that adds the rows and one equation that adds the columns. Show that the totals match.
24. Buttons
Aisha has 18 buttons. She wants to make an array with 4 rows of 5 buttons. How many more buttons does she need?
What does a 2nd grade arrays worksheet practice?
Problems 1 and 2 count rows, columns and dots in each row. Problems 3 and 4 then write equations that add the rows and the columns. Next, problems 5 and 6 repeat the idea with two rows of three and five rows of two. Because the pictures are small, children can count every dot.
How do the stories build the skill?
A muffin tin has 3 rows of 2, and a window has 4 rows of 3 panes. A van has 5 rows of 2 seats, and Maya’s page holds 4 rows of 5 stickers. Each story pairs a real object with an equation.
Which problems work backward?
In problem 15, the equation 3 + 3 + 3 + 3 + 3 = 15 appears, and children say how many rows it has. Next, 12 dots in 4 equal rows ask for the number in each row. Finally, Aisha’s story asks how many more buttons Aisha needs to make 4 rows of 5 from 18 buttons.
What is the mistake in problem 22?
Diego has 4 rows of 5 but writes 5 + 5 + 5 = 15. He added only three rows. The right equation has four 5s and totals 20.
How should you finish this page?
Draw a quick sketch for any story that feels tricky. Then match the number of addends to the number of rows. Last, use the key to confirm your totals and redraw one missed array.
