App Description

The Montessori Subtraction Charts help children memorize the subtraction tables with a unique Chart System developed by Maria Montessori! This app will fit perfectly into any school system and is self-correcting so no extra supervision is required. For children ages 6 & Up.

Our team was one of the first to develop Montessori inspired apps starting in 2010, and our design & method is guided and approved by Manel Wickremasinghe, an AMI certified Montessori teacher with over 40 years of teaching experience.

In the first set of activities, children can practice individual subtraction sets, such as 11-5, 9-5, 5-5, etc, as well as, the complete chart in one activity. In these activities the solutions to the equations can be seen on the board, helping the child know which answer to search for among the scrambled numbers at the bottom of the screen.

In the advanced activity children can practice individual subtraction sets or the entire chart at once by finding the solutions without seeing the numbers on the board, thus, testing their memory.

REVIEW FROM ONE OF OUR CUSTOMERS using the ADDITION CHARTS app:

"Thanks for posting the new addition app. My 3-year-old had a chance to try it out. She loves it. I actually intended for my 6-year-old to do the work, but she chimed in and they did it together. Thank you for putting so much thought and detail into your apps."

We are confident you will find this SUBTRACTION CHARTS app, just as useful!
