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.

Engagement

Engaging, especially for kids who have already been introduced to physical Montessori materials. Numerous settings on this well-designed app help kids start at their current math level. Difficulty grows as kids master their current level.

Learning Approach

The main activities are based on Montessori tools, and often include similar skills that build upon one another for kids to master adding and subtracting large numbers. Games and monster-making are just for fun practice and reinforcement.

Support

A thorough explainer page under the "Note to Parents" tab provides the rationale behind each activity, and tips on how to customize gameplay settings.

Self-Direction

  • working efficiently

Kids can learn the concepts and methods behind adding and subtracting large numbers, including carrying and borrowing. Kids can also learn to apply the Base 10 system to problems involving larger numbers, and practice using the Montessori system of color-coding. As kids work to solve larger addition and subtraction problems and play the games under time pressure, they are also growing in math operations proficiency and speed.

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?

QUALITY

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.

Families can talk about...

  • Use the settings options to customize gameplay for your child's current math level.

  • Explain some of the systems that make math more predictable, such as color-coding, groups of 10, and tables.
