Teachley: Subtractimals
© 2015 Teachley, LLC
This is the follow-up to Addimal Adventure (2014) using single-digit subtraction to help some animals. Subtractimals is a "virtual manipulative" that helps early elementary children break down and visualize the steps involved with single digit subtraction. The app contains animal characters including the sinister Professor Possum, Patooey and her cousin, Slurp. There are different modes of learning, including a speed round that encourages memorization but provides strategy hints when needed. Subtractimals teaches effective math strategies and scaffolds learning to promote conceptual understanding and fact fluency. This is a "Math fluency" app -- Most fluency apps focus on drill with digital worksheets and flashcards. In contrast, Subtractimals teaches math strategies to build conceptual understanding. The app is Common Core-aligned, and allows teachers to create or log in to their existing Teachley accounts, so they can to customize the experience for each child.
