This Instructional Activity is a part of the Lesson 6, Unit 2, Grade 6. Today, we work with partitive division. Let's find the quotient of using the partitive division interpretation. We use the partitive interpretation and interpret the divisor, 2 thirds, to be the number of groups. I'm asking myself, "50 is 2 thirds group of what size?" Draw a model. How many units do we draw? How do you know?
