Lesson objective: Divide whole numbers by a two-digit divisor using partial quotients.

This lesson helps to build the procedural skill of dividing whole numbers. Partial quotients is used here because it extends student work with area models and arrays, and provides another approach to solving division problems. This work develops students' understanding that a variety of strategies can be used to solve real world problems.

Students engage in Mathematical Practice 8 (Look for and express regularity in repeated reasoning) as they connect principles of place value and operations to efficiently solve problems.

**Key vocabulary:**

- area model
- partial quotients
