App Description

This app is an extension to the Montessori Hundred Board to help children with their counting from 1 to 100 using Roman Numerals. The board and the number squares are exact replicas of these classic classroom materials!

Three lessons are included:

1. Standard sequencing from 1 to 100 (with or without a control).
2. Even numbers only.
3. Odd numbers only.

The child has to search for the next appropriate number in the scrambled numbers on the right side. When they choose the correct one the number will automatically move into position on the board. You'll be pleasantly surprised at how long it takes to finish! At the bottom a score is presented for parents to observe how their child is progressing.

This activity is a time-tested, teaching tool used in the Montessori classroom that children enjoy doing. The app itself was co-developed and approved by an AMI certified Montessori teacher with over forty years experience. Use this app as a complement to your child's classroom education and as a follow-up to the other Montessori applications in the app store! Your child will enjoy this challenging and fun activity!


Please look for our other follow-up apps to the Hundred Board, including 101-200 and Skip Counting! Both are now available in the App Store.

We sincerely thank you for your support!
