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.

Verdict

The call

The clearest difference is price: Rounding at Free against Partial Product Multiplication's $3.99. Rounding also leads on rating (4.0 vs 2.5) and ratings volume (79 vs 2). Partial Product Multiplication's advantage is in-app purchases (none vs 1) and ads (none vs shown). On review sentiment, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Rounding holds the better App Store score, 4.0 against 2.5. That said, the two scores are not equally well evidenced: Rounding has 79 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Partial Product Multiplication's written reviews are positive against 64% of Rounding's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Partial Product Multiplication ships an update every 8 months, Rounding every 12 months. The most recent releases landed on September 21, 2026 and June 1, 2026 respectively.
