Grade 4 Multi-Digit Multiplication Worksheets, Partial Products

Product Description

If both factors have two digits, the student could multiply the tens and ones and skip the two cross products. The pages for area models make these pairings visible. The student labels the factors or uses place value parts, multiplies the pair, and adds the partial products. The key shows how an expanded factor becomes the smaller factors which become the partial products for the precise product.

Part 1 works with a one-digit multiplier and goes up to four-digit multipliers. Part 2 has two-digit factors and includes factors where the digit in the ones place is a zero. Students also round factors to estimate products and evaluate a classmate's answer. This gives a purpose for discussing not only the digits in the result but also its size.

The application pages use trays, groups, seats, and other situations where the factors represent the number of groups and the quantity per group. Encourage students to identify the quantities before multiplying. For an intervention activity, go back to one area model that has been completed and relate each box to a term in the equation.
