DT125 Four-Object Sorting Tray with Shells
We have this tray made locally exactly to our specifications. The smooth sides of the indentations make it possible for the child to feel the shape of even the tiniest bean or seed, for sorting with eyes open, and eventually blindfolded.
This tray is for sorting 4 kinds of objects. It is 7" x 12", made of finely polished hardwood. The set of forty small shells contains ten each of four different kinds. One can also, of course, use pebbles, beans, buttons, many different sorting objects.
