Partial Products Multiplication
Learning Objective
I can multiply a two-digit number by a one-digit number using partial products.
Key Concepts
When multiplying 37 × 6, we can break up 37 into 30 + 7 and then multiply each by 6.
37 × 6 can be expressed as (30 × 6) + (7 × 6), which equals 180 + 42, resulting in a final answer of 222.
Using the column method, we multiply the ones place (7 × 6 = 42) and the tens place (30 × 6 = 180) separately, then add these partial products to get the final product of 222.
