Lesson 9
The Birds
Lesson Purpose
The purpose of this lesson is for students to use whole-number multiplication to solve problems.
Lesson Narrative
In previous lessons, students learned to use the standard algorithm to multiply multi-digit numbers. In this lesson, they solve problems that involve multiplication. Students are not asked to use a particular algorithm when they solve these problems. Some of the numbers in the problems are large and cumbersome and lend themselves well to using the standard algorithm for multiplication. Other products have factors of 10 and other smaller factors and these lend themselves well to mental calculations or use of the associative and commutative properties of multiplication. Use this lesson as an opportunity to observe the strategies your students are applying.
