An array is a group of objects, pictures, or numbers in columns and rows. An array can be interpreted in two ways, and you can teach your kids those two ways with this colorful, fun worksheet. First, an array can be represented in terms of rows, as shown in the picture. That is, 3 rows in 4 places make 12. Or, an array can be represented in terms of columns, as also shown in the picture. For example, 4 columns in 3 places make 12. Note that both cases always amount to the same sum. Now, help your child trace on the dotted lines from the number sentences to the cars that match.
