Choose your license above: Personal for your home or classroom, Commercial if you want to print and sell.

One cube. One bar. One square. And suddenly a big number makes sense.

Small fingers drop a single red cube into the green tray. Click. Then a bar of ten into the blue one, and a whole square of a hundred into the red. "One hundred and eleven!" The number tiles stand up behind each tray, and the number is right there, made with their own hands.

The Montessori Counting Cubes & Place Value Trays set is a complete decimal system corner you print yourself. Every file comes pre-coloured in 3MF according to traditional Montessori colours, so multicolour printing is effortless. Designed in the Playtessori Studio and test printed on standard FDM printers.

⚠️ This is a DIGITAL DOWNLOAD (STL/3MF files). No physical items will be shipped.

Smart printing tips for the number tiles
