The Montessori Subtraction Charts help children with the memorization of the essential differences of subtraction!
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.
This activity is a time-tested method of reinforcing the basic subtraction differences and is used in Montessori classrooms around the world! This app was co-developed and approved by an AMI certified Montessori teacher with over 40 years experience in the field!
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!
Thanks for your support of our Montessori apps!
