TOPIC 5

Use Models and Strategies to Divide Whole Numbers

Students will use place-value patterns and mental math to find quotients and use compatible numbers and place-value patterns to estimate quotients.  Then, they will use models to find quotients and solve division problems using partial quotients.  Next, students will find the quotient when the divisor is a multiple of 10, and decide where to place the first digit of the quotient when dividing whole numbers.  Finally, they will use estimation to decide whether a quotient is reasonable when dividing two-digit numbers.
