I've been collecting prices from a bunch of Montessori suppliers for various materials. It's amazing how big a price range there is for some products. For example, the least expensive Hundred Board is $22 while the most expensive is $166! Here's what I have so far:
Constructive Triangles
Continents Globe
Golden Beads
Grammar Symbols
Home Country Puzzle Map
Hundred Board
Large Bead Frame
Long Rods (Red Rods)
Multiplication Board
Multiplication with Bead Bars
Mystery Bag/Box
Number Cards
Pink Tower
Sandpaper Globe
Small Bead Frame
Sound Cylinders
Stamp Game
Trinomial Cube
World Puzzle Map
I have no idea what sort of variation in quality there is between all of these. I could see it mattering with things like the Puzzle Maps, but the Number Cards shouldn't really make a difference. I've seen plenty of official Montessori classrooms with Number Cards on laminated card stock.
