Classroom Resource

Subject Area

Mathematics

Grade(s)

4

Overview

When first learning to multiply two 2-digit numbers, students will use the area model. To start, students will use their knowledge of place value to decompose into tens and ones. To decompose means to break apart. This video will introduce students to this strategy. 

Mathematics (2019) Grade(s): 4

MA19.4.11

Find the product of two factors (up to four digits by a one-digit number and two two-digit numbers), using strategies based on place value and the properties of operations.

Knowledge

Students know:
  • How to compose and decompose numbers in a variety of ways using place value and the properties of operations.
  • How to represent the product of two factors using an area model.
  • Use strategies based on place value (partial products), the properties of operations, arrays and area models to represent a two digit factor times a two digit factor.

Skills

Students are able to:
  • Use strategies based on place value and the properties of operations to find products.
  • Illustrate the product of two factors using rectangular arrays and area models.
  • Explain the product of two factors using equations.
  • Make connections between models and equations.

Understanding

Students understand that:
  • arrays, area models, place value strategies, and the properties of operations can be used to find products of a single digit factor by a multi-digit factor and products of two two-digit factors.
