About this resource
Description
Arrays are a sweet way to see equal groups. This sweet rectangular arrays addition activity helps 2nd and 3rd grade students find the total number of cupcakes in arrays with up to 5 rows and 5 columns, then write the total as a sum of equal addends, with one addend for each row.
Children pick a cupcake array card, count the cupcakes in one row, count the rows and add one row at a time. Then they hunt for the lettered equation card that adds those rows, such as 4 + 4 + 4 = 12, and record the letter and the total on the Array Match sheet. The cards also make a fun memory game. A 2nd grade practice page shows four new arrays for children to turn into addition sentences on their own.
What’s Included
- A colorful cover page
- A How to Use page with simple steps
- 10 cupcake array cards and 10 lettered equation cards
- An Array Match recording sheet
- A 2nd grade practice worksheet
- An Array Match answer key and a practice answer key
Why This Activity Helps Kids
- Seeing equal rows in an array builds the idea of equal groups, the first step toward multiplication.
- Writing a sum of equal addends links the picture to a number sentence.
- Matching cards gives quick feedback, so children can spot and fix mistakes.
Ideas for Teachers and Parents
Use the cards at a math center or with a partner. Build the arrays with real counters or cereal pieces before matching. Older students can write a multiplication sentence for each array too. This 2nd grade arrays activity is a great bridge into skip counting. Come back to the sweet rectangular arrays addition activity whenever your class needs a fun review.
