Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
This lesson introduces a method of division that supports a conceptual approach by dividing up two digit numbers by one digit. This lesson is intended to be the entry level and contains modifications for both lower and higher level students.
Using an interactive website, students use the Sieve of Eratosthenes to help them discover prime numbers, understand divisibility and inverse relationships between multiplication and division.
