4th Grade Mathematics
UNIT 2: Multiplication
Our unit on multiplication is approximately 10weeks long; by the end of the unit, students will know how to multiply a multidigit number by 1 digit and a twodigit by a twodigit using many different strategies that emphasize conceptual knowledge. In Chapter 2 and 3 of our math text, students will explore and discover answers to the following essential questions:
 What strategies can you use to multiply by 1digit numbers and 2digit numbers?
 How can you use models to multiply a multidigit number by a 1digit number?
 How does the partial products strategy use place value?
 How can you use place value to multiply 2digit numbers?
 How can you use estimation to check your answer?
Go Math  Chapter 2
In Chapter 2, students will learn how to do multiplicative comparison problems, which helps them build their knowledge of multiplicative relationships and fact families. The example on the right shows how students will learn how to use models and diagrams to demonstrate their knowledge. Students will also learn how to estimate products and use the distributive property of multiplication to multiply.

Go Math  Chapter 3
In Chapter 3, students will apply what they know about the properties of multiplication, along with their knowledge of multiple methods of multiplication (partial product, distributive property, area model, and standard algorithm) to multiply 2digit by 2digit numbers. Like chapter 2, conceptual understanding and place value is stressed in this unit. Students will also rely on their understanding of estimate to determine if their product is reasonable.
