Subtractimals is the eagerly awaited follow-up to Addimal Adventure, a 2014 Apple Design Award winning app. This app teaches children important strategies for solving subtraction problems. What are people saying? "Teachley's new app, Subtractimals is the perfect follow on to Addimal Adventure! This new subtraction app encourages the same deep mathematical thinking and grows with each student while guiding them in the process of subtraction." - Mauri Dufour, Kindergarten teacher and Apple Distinguished Educator "Subtractimals builds on Addimal Adventure by providing kids with important strategies for learning subtraction. Our students love playing Teachley's apps and have greatly enhanced their addition and multiplication skills. We cannot wait to start using Subtractimals too!" - Cathy W., K-4 Instructional Technology Coordinator About the game: The sinister Professor Possum makes his return in Subtractimals. In this app, kids use subtraction strategies to help Patooey and her cousin, Slurp thwart his latest evil plan. Developed by former teachers and experts in children’s cognition and learning, Subtractimals is an engaging game that teaches single-digit subtraction. During the tool round, children practice using important math strategies while the speed round encourages memorization but provides hints when needed. Most fluency apps focus on drill with digital worksheets and flashcards. In contrast, Subtractimals teaches effective math strategies and scaffolds learning to promote conceptual understanding and fact fluency. The app is also great for parents who want to support their children’s learning at home. Recommended Grades: K-2, 3-5 (intervention) Meets Many Common Core, TEKS, and other state standards. About Teachley: Founded by former teachers, Teachley uses cognitive science research to create apps that teach effective learning strategies and assess what kids know within engaging games. Our team includes experts in cognition and learning, Grammy and Emmy-award winning creative talent as well as new and noteworthy game designers. www.teachley.com *This app was made possible by the Federal Department of Education, with funding provided by the Institute of Education Sciences’ SBIR program.

ReceptionRating · Positive reviews · Number of ratings

Teachley Subtractimals holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: AB Math II has 34 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 76% of AB Math II's written reviews are positive against 60% of Teachley Subtractimals's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

AB Math II ships an update every 7 months, Teachley Subtractimals every 14 months. The most recent releases landed on November 7, 2026 and November 1, 2026 respectively.
