Lesson 3

Workshop: Multiplication Methods

Est. Class Sessions: 1–2

Before the Lesson

Review student work and progress from previous lessons to guide instructional decisions about the following Expectations:

E1. Demonstrate understanding of the place value concepts and mathematical properties involved in multiplication of 2-digit by 2-digit numbers (e.g., use the distributive property to multiply).
E2. Show connections between models and strategies for multiplying 2-digit by 2-digit numbers (e.g., demonstrate partial products using a rectangle model for multiplication).
E3. Estimate products of multidigit numbers.
E4. Multiply 2-digit by 2-digit numbers using mental math strategies and paper-and-pencil methods (e.g., expanded form, all-partials).

In Part 2 of the lesson, students will choose problems based on self-assessment of their progress with these Expectations. Use your own evaluation of students' progress to help guide their choices.
