What you'll learn
- 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)
- Use an area model (rectangle diagram) to organize and visualize the partial products in a multiplication problem
- Multiply a whole number of up to four digits by a one-digit whole number using strategies based on place value
- Multiply two two-digit numbers using an area model and partial products
- Illustrate and explain why a multiplication strategy works by connecting the visual model to the written equations
