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.
