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

Love the idea - LITE version indeed!


The LITE (or free) version should at least let you go all the way to 100. After 25 you click 26 and it counts as incorrect and takes you to the "buy the full version" screen. As a 'Montessori mom' I think these apps are a fun way to reinforce what they're learning in school when away. I do also think the numbers need to be randomized in the 'tray' each time too - otherwise it's a not learning, but memorizing a location!

Needs changes


I like this app and would by the full version, but when you reset the chart it places the numbers in the same spot every time. Instead of learning the number order, my students are memorizing where the numbers are.



Clean and simple design, easy for children to navigate and use. Worth a try!
