Enjoy this lite version of the famous Montessori Hundred board!

Full version description:

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.

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!

Ratings and Reviews

Lite version not good.


Very disappointed that this lite version only allowed my little one to count to 10.

Only works up to 25


I realise that this is the free version but this app only works up to the number 25. When you press 26 it switches to an info page and you can't go back. I downloaded the trial because I was considering buying the app but this is not enough to assess it as you don't see what happens when the child gets to 100. Not to mention the fact that my son worked hard to get to 25 and was then upset when it disappeared. Not at all the standard that I expect from Montessori.
