Once the times tables are solid, children can use them on bigger numbers that end in zero, like 40, 70 or 500. This 3rd grade multiplying multiples of 10 worksheet shows how. It has 12 problems written in columns, labeled a to l, with a whole number from 1 to 18 under each top number. The top number is 10, 20, 30 and so on, up to 500. A boy with a stick runs past the title, and a girl stretches in the corner. Most products stay under 1,000. A second page gives the answer key.
