Students recall division facts with products through 100 and divide two-digit and multi-digit whole-number dividends by one-digit divisors using place value, partial quotients, area models, or the standard algorithm. They divide typically up to four-digit dividends by two-digit divisors, estimate quotients using rounding and compatible numbers, and verify results with multiplication while expressing remainders as less than the divisor. Students solve division word problems involving equal groups or group size, represent relationships with equations or models, and interpret remainders as leftovers, ignored quantities, or additional groups, with limited contexts involving a unit fraction divided by a whole number.
