Right Mind Math (RMM) is a Free & Open Source Software math app. It develops instant recall for simple arithmetic.

RMM also teaches easy solutions for multi-digit and long-division problems given instant recall for single-digit arithmetic.

RMM can be run on most devices as a local app called a Progressive Web App (PWA). It is also Free, and 100% Private.

Daniel Kahneman (Nobel Prize winner) best sums up RMM's raison d'etre:
Acquisition of skills requires a regular environment, an adequate opportunity to practice, and rapid and unequivocal feedback about the correctness of thoughts and actions.
That is our design/learning philosophy — and a key benefit for your child. This is what we call right-mind learning.

The main reasons to use RMM:

  • Helps you show engagement & interest
  • Optimized for right-mind learning
  • Free & Open Source — forever
  • Pretty darn well-designed app
  • 100% private

Item one (engagement & interest) is the most important factor at work here. Engaging with, and being interested in your child's learning process is much, much more important than the app you use. Fortunately RMM makes this easy & natural for you.

A series of Topics is below. Yes there are a lot of them. They hopefully both explain RMM completely, and help you best assist your child. Please take the time to read them. As you read the Topics it may help to click the link below to run RMM for reference in a separate window.

Check It Out:

To evaluate RMM by running the actual app Click Here (opens a new window). Please note:

  • The app thats runs in the browser window opened with this link will be the same as the app you install as a PWA.
  • The first time you open the RMM app you are prompted to provide a device name. This is used to initialize the your browser javascript database (IndexedDB).
  • Since RMM is a PWA, it enjoys the very deep and robust browser security features developed ensure user security (e.g. the database identified above).

If you like RMM after trying it, continue reading. You will need to invest some time doing this. It will be worth it.

Reference:

• A recent authoritative study titled What the Science of Learning Teaches Us About Arithmetic Fluency explains the benefit of arithmetic instant recall as a means to more easily learn math. It concludes:
We described how understanding of numbers, relations, and operations—collectively referred to as 'early number sense'—serves to bootstrap fluency...
The study can be found here. (opens in new tab)

• This YT video is an interesting take on RMM (terms used are "sharp focus" (left mind)' vs. "open focus" (right mind). Note how Jeff calls out how sharp focus can be "confusing" — is this what you want your child to exerpience learning basic arithmetic? Link (opens in a new window possibly with a YT ad at the start)

More About PWAs:

RMM is a Progressive Web App (PWA) like the original Wordle. (Unlike Wordle, RMM is both Free & Open Source.) Even though RMM runs great in a web browser window, it is important to install it as a PWA (see topic below).
