My Montessori training center, MECA-Seton in Chicago, had monster requirements of their future graduates. We made vast quantities of materials for approval by sage, Celma Perry. Our final opus was a Montessori thesis. Here is a condensed version of mine posted in parts for you to view.
I was working on my masters in clay when I discovered Montessori.
Practical Life and Math in Clay
What better complement to flowers than the earthiness of a clay vessel.
Wheel thrown and hand built vases
Miniature pitchers for rice or water pouring exercises
Matching pitcher and bowl sets
Tweezer Sorting Exercises
Tiny squares are paired according to dots of color
Extruded geometric and decorative colored-clay shapes are grouped according to likeness
I carved the original pattern into a plaster stamp to decorate these clay slabs with leaf and flower motifs.
Clay rings paired according to natural clay color.
Clay counters. What a relief from those plastic discs!
