In earlier lessons, students learned to divide two digit numbers by one digit numbers when regrouping is required. Regrouping is required with the division of the digit in the tens place of the dividend by the divisor results in a remainder in the tens place.
In this lesson, students extend that knowledge to learn to use the standard algorithm to divide a three-digit number by a one-digit number when regrouping is required in one or more places.
In this lesson, students extend what they have learned about using the standard algorithm to divide a three-digit by a one-digit number to division problems in which a four-digit number is divided by a one-digit number.
