Polygon 3 part cards
Umamah Learning Academy Style
I printed out these cards from Free Montessori, titled Polygons. You will find the control chart in the first list and the nomenclature cards in the second list. The pictures are quite self explanatory.
I ended up improvising an extension as Lil Muallimah counted the sides and wanted to place her beads.
She really enjoyed counting the sides and making the shape with the beads. All set for next time :)
