Multiply a whole number of up to four digits by a one-digit whole number

What you'll learn

1. Decompose a multi-digit multiplication problem into partial products using place value (e.g., 3 x 423 = 3 x 400 + 3 x 20 + 3 x 3)
2. Use an area model (rectangle diagram) to organize and visualize the partial products in a multiplication problem
3. Multiply a whole number of up to four digits by a one-digit whole number using strategies based on place value
4. Multiply two two-digit numbers using an area model and partial products
5. Illustrate and explain why a multiplication strategy works by connecting the visual model to the written equations

Prerequisites

• Recognize that in a multi-digit number, a digit in one place represents ten times what it represents in the place to its right
• 3-nbt-a-3
