4th Grade Math Worksheets

Fourth grade moves into multi-digit work: students read, round and compare numbers to a million, multiply up to four digits by one digit, and divide with remainders. Fractions grow to equivalence, adding and subtracting like denominators, multiplying by whole numbers, and tenths and hundredths as decimals, alongside measurement conversions, angles, and lines of symmetry. Every worksheet below is free, prints as a PDF with an answer key, and can be assigned online.
