Montessori Math: Add & Subtract Large Numbers
Did we miss something on diversity?
Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.

The parents' guide to what's in this app.
What Parents Need to Know
Parents need to know that Montessori Math: Add & Subtract Large Numbers uses systematic, color-coded math activities to help kids learn skills that are required to add and subtract large numbers, such as carrying and borrowing. From the creators of Montessori First Operations, the number range on this more advanced app is much greater: from 0 to 9,999. Kids should at least be comfortable with two-digit numbers before progressing to the games here.

What’s It About?
Kids can play three Montessori-themed activities and three fun games. As they do so, they earn points that can be spent in the Monster Shop on parts to build monsters. There's also a "magic slate" that kids can write on or tap numbers to solve problems. Parents can tailor the app to each user's current level.
Is It Any Good?
Montessori Math: Add & Subtract Large Numbers uses some very interesting, systematic visual and organizational clues to help kids grasp the concepts required to solve addition and subtraction problems with large numbers. Color-coding place values (green for thousands, red for hundreds, blue for tens), using the Base 10 system, and moving from concrete to abstract in the activities all help kids learn. The points-as-rewards system is not necessarily in the spirit of the Montessori philosophy. Overall, this app is not a replacement for hands-on Montessori math tools, but it can be a fun digital supplement.
