In this Grade 5 Eureka Math lesson, students connect area models and the distributive property to partial products of the standard algorithm with renaming. Using problems like 64 × 73, they decompose multi-digit factors, identify how each partial product from the area model corresponds to a step in the standard algorithm, and practice renaming tens and hundreds during multiplication. The lesson builds fluency with multi-digit whole number multiplication while reinforcing the relationship between visual models and symbolic procedures.
Section 1
Multiplying Mixed Numbers with an Area Model
To multiply two numbers using an area model, decompose each factor into its place value components.
The total product is the sum of the partial products obtained by multiplying each component of the first factor by each component of the second factor.
For factors and , the product is:
