Adding and Arrays Worksheet

Arrays turn addition into a picture a child can actually see. When squares are lined up in equal rows, a second grader can count the rows, add the same number again and again, and find the total without counting one square at a time. This Adding and Arrays Worksheet gives students six rectangular arrays to study and two story problems to solve, so repeated addition becomes a strategy they reach for instead of a rule they memorize. An adding and arrays worksheet is one of the clearest ways to build the bridge between addition and the multiplication work that comes next.

On this printable page, students look at each array, add the rows, and write a number sentence such as 4 + 4 + 4 = 12 on the solid line below it. Part B moves the same thinking into two short story problems about a tray of muffins and rows of carrots in a garden bed. This repeated addition worksheet keeps every total at 20 or below, so the numbers stay friendly and the focus stays on the structure of the array. Use it as morning work, as a small-group warm-up, or as a quick check after teaching equal groups.

What’s Included

• One printable worksheet page with six rectangular arrays to turn into addition equations
• Two real-world story problems built on rows and equal groups
• Solid, roomy writing lines sized for second grade handwriting
• A complete answer key on the final page
• A print-ready PDF you can reuse with every class

This activity helps children in three ways. First, it makes equal groups visible, so students stop counting by ones and start adding by rows. Second, writing the whole number sentence instead of just the answer builds the habit of showing mathematical thinking, which is exactly what second grade addition standards ask for. Third, the story problems ask students to picture an array they cannot see on the page, and that mental step is the one that carries them into multiplication next year.

Teachers and parents can stretch this page further. Build each array with counters, cereal, or square tiles before writing anything down, and let students say the equation out loud as they touch each row. Ask a child to turn one array sideways and notice that 3 rows of 4 and 4 rows of 3 both make 12. At home, hunt for arrays in real life — an egg carton, a muffin tray, a window pane, the tiles on the kitchen floor — and write a number sentence for each one on scrap paper.
