*****Used in schools and by parents all over the world! *****

This app is now promoted by the Australian Institute for Teaching and School Leadership as an effective app for learning number sequencing techniques!


This app is a fun and educational exercise found in the Montessori classroom to help children with their counting from 1 to 100. 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.
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.

In the Japanese version, children can also practice counting 1 - 100 using Japanese characters!

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 teaching introductory math! Your child will enjoy this challenging and fun activity!



"This looks very simple, but, you'd be surprised how engrossing the children find this lesson to be. I've watched our five year old daughter spend over an hour working with it, trying to get to a hundred!"

"Our son (6) started first grade and is ecstatic to be the only kid to write all the numbers from 1-100! Your app is fun to him!"


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

We sincerely thank you for your business!
