Production Notes - Beta Edition V2.0
Montessori stamp game is for performing arithmetic with numbers less
than 10 000. Before using this material, a child must grasp the idea
that in our number system we represent a group of ten objects with one
object of a higher category and that exchanging must take place when
we add and subtract numbers.
There's a great demo about how to use the stamp game made in Flash by the Montessori Academy of Evansville, Indiana. It's sort of interactive -- waits for you to click on the next object which has to move, then illustrates it. Not true simulation because there is no counting, but nevertheless impressive.
The stamp game is one of the Montessori favourites! Typically it is used by children (ages 4-7) for both static and dynamic addition, subtraction, multiplication and division. This electronic version only supports addition and subtraction, but it incorporates "snap" to keep work neat, group select, and hot keys for rapid category exchanging. The stamp game also monitors the user's activity, offering help and instructions. This is the first material we developed which keeps score. Watch out for stamps snapping on to each other - use the hot keys. Calculation limit 9 999.
The circular chips above the stamps hold the place
for a category with 0.
|The stamp game's memory resets with each new question to avoid confusing the child with undo steps from a previous question.|
The stamps occasionally snap over one another. Use of the hot keys, or releasing a stamp on equal sides of an opening with minimize this tendancy.
No tutorial has been developed as yet. Version 2.0 incorporates Flash buttons with effects, a new layout, and new colour scheme. Some improvements have also been made in the logic.
