3rd Grade Math Worksheets
Third grade is the year of multiplication and division: students learn what they mean, master the facts within 100, and solve one- and two-step word problems. They also meet fractions as numbers on a number line, round and add within 1,000, find area and perimeter, tell time to the minute, and read scaled graphs. Every worksheet below is free, prints as a PDF with an answer key, and can be assigned online.
