Multiplying by 1-Digit Numbers Using Partial Products: Missing Numbers

Help students boost their multiplication know-how with this partial product worksheet! Growing mathematicians are given nine problems to work through, each of which requires multiplying a multi-digit number by a one-digit number. Students will fill in the missing partial products in each problem to find the final product. 

Geared towards fourth and fifth graders, this worksheet reinforces how to break numbers down into partial products when multiplying by single-digit numbers. Using the partial product strategy can be helpful when multiplying larger numbers and can promote confidence in mental math strategies. Mastering this strategy also prepares students for more difficult multi-digit multiplication problems in the future.
