Partial Products Multiplication helps students learn and practice the partial products multiplication method step by step. The app gives students a visual way to multiply numbers by breaking the problem into smaller partial products. The partial products are then added to find the final answer. Students can solve randomly generated problems or enter their own multiplication problems. The Partial Products Method: In the partial products method, each place value is multiplied separately. For example, in 39 × 24, the partial products are 36, 120, 180, and 600. These are then added together to get the final answer: 936. Teacher endorsements: “The math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary. They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice.” — R. Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada “There are students who see my examples who still need some guidance, and after using your app have said, ‘Now I get it.’ The feature of selecting possible solutions in each step helps some of my students who are still building their multiplication facts.” — Z. R. Prowell, Highlands Elementary, Edina, Minnesota, USA Easy to Use: The numbers are aligned automatically so students can focus on solving each step. After the student solves each partial product, the correct answer moves into the right place. If the student presses the wrong button, the answer appears above the keyboard but does not move.

This is a robbery, it is useless,it does not say if the result is wrong. ### 5/5 — Clear and simple practice tool *2016-03-10* This is a clear and simple learning tool for 10 or 11 year olds. It doesn't quite follow the same format as I learned in the 1980s - when multiplying a number in the 10s column, we automatically added a zero in the 1s column of the result line underneath, and worked across. But this 'partial products' method works just as well, and my 9-year-old daughter tried it out successfully, despite saying she hadn't been taught it at school yet. ### 4/5 — Helpful app *2013-05-22* For those of us who did not use the partial product method when we learned how to multiply large numbers this app is very helpful. It helped me understand the algorithm. I was better able to explain it. My third grade son was having some trouble "seeing" how the process worked and this app broke down the steps for him and gave him visual cues. After just one session he felt that he did not need the color cue anymore and the number prompts were enough. It is an expensive app, but given the level of frustration over homework that has been diffused in my house it was well worth the price. My son is feeling much more confident now. I can see this app also being very helpful in a classroom to give support to visual learners and to those who need help remembering the steps of the algorithm. ## Frequently asked questions about Partial Product Multiplication ### What is the partial products multiplication method?
