An array shows equal groups in rows and columns, so a multiplication can be read straight from the picture. This 3rd grade expressions for arrays worksheet has five arrays of cups, hearts, balls, dots and squares. For each one, your child counts the columns and the number in each column. Then they write the multiplication expressions on the lines and find each product. The first array is worked out as an example, where 3 columns of 5 cups give 3 × 5 = 15 cups. The answers go up to 60, from 5 × 4 = 20 hearts to 10 × 6 = 60 dots. The second page is an answer key with every expression and product.
