The WCPSS Math Department produced this video to support teachers as they teach the unit Strategies for Division in the grade 4 math curriculum.
The expanded notation strategy uses the division bracket. The quotient is built place value by place value above this bracket. These partial quotients are added together to solve the division problem.
Students often make the connection between division with expanded notation to the standard division algorithm. The division algorithm is not an expectation in the math curriculum until middle school.
