2025 MidSchoolMath National Conference

In this session, we'll look at two key strategies to support students in understanding and doing long division. We'll move away from the basic DMSB acronym, and look different ways attack division through the lens of multiplication/creating equal groups and counting up.

Using the question "How many groups of X fit inside Y?" and partial quotient strategies will prepare you to be able to teach division without the use of DMSB. These strategies can be used to teach division to students, whether it is the first time it's being taught or data suggests there is an intervention needed. You'll leave with experience in the strategies and handouts so that you can use these approaches with your students.
