Lesson 8
Multiplication Fluency
Lesson Purpose
The purpose of this lesson is for students to play games to continue to develop fluency with multiplying multi-digit numbers with the standard algorithm.
Lesson Narrative
In this lesson, students continue to find products of a 2-digit number and a 3-digit number with a strategic goal. They continue to play Greatest Product and they also use 5 given digits to try to make a product that is as close as possible to a given number. This is more challenging than making the greatest product as rather than putting the largest digits in the largest place values students will need to experiment or reflect about how each digit in the numbers influences the value of the product. This lesson provides an opportunity for teachers to observe students as they use the standard algorithm and offer support, as needed.
