Unit 3, Lesson 10
Concepts of Division (Optional)
Grade 5
Preparation
Lesson Narrative
In this optional lesson, students revisit whole number division considering the relationship between dividend, divisor, and quotient. This lesson attends to concepts of division developed since IM Grade 3. Students examine the relationship between the numbers in division problems and compare the size of the quotient by reasoning about the relative sizes of the divisor and dividend. This prepares them to make sense of division involving whole numbers and unit fractions in subsequent lessons.
