Number Sequencing

What Comes Before, After & In Between

These activities are also available in our complete Montessori Math app.


This is one of our most popular apps with schools. After learning how to count up to 100, children sometimes struggle with the concept of the sequence of numbers out of order.

In her classroom, Manel Wickremasinghe would make-up sheets with rows of numbers on them for children to write down the appropriate number that would come either before, after or in between the number(s) on the sheets. Those hand-made activities became the basis for this app.

The app is setup in a simple manner for children to navigate and it is self-correcting so they cannot place the numbers incorrectly. the child can fill out the sheets in any order they choose. The app keeps track of their progress, discretely presenting the number of correct & incorrect actions for parents/teachers to evaluate progress.

Thanks for your support of our Montessori apps!
