GAM Rough Gradation Tablets

The set has 5 pairs of tablets, each carrying a different grade of rough surface, mounted on solid beechwood tablets measuring 13.5x9 cm. A box is included for storage. Because the roughness is graded in pairs, the child can both match and order the surfaces from least to most rough.

These montessori sensorial materials isolate texture so the child focuses only on how rough each surface feels. By running the fingertips over the tablets, matching pairs and then grading them from smoothest-rough to roughest, the child sharpens tactile discrimination and learns to notice fine differences the eyes alone would miss.

Each tablet is a solid beechwood board measuring 13.5x9 cm, a size that sits comfortably under a child's fingertips. The uniform shape means only the roughness changes from tablet to tablet, so nothing distracts from the tactile comparison the exercise is built around.

A child often works with fingertips lightly, sometimes with eyes closed, feeling each surface in turn. With 5 pairs they first match identical grades, then arrange the surfaces in order from least to most rough. Matching in pairs offers a built-in check, since a correct sort leaves no odd tablet.

As a sensorial exercise in tactile grading it suits preschool children who can sit and attend to feeling small differences with their fingers. It usually follows simpler rough-and-smooth work, once the child is ready to grade several degrees of roughness rather than judge only two.

Return the tablets to the included box after use and keep them out of direct sun and away from damp, so the beechwood and the rough surfaces stay in good condition. Wipe the wooden edges with a soft, just-damp cloth, taking care not to soak the textured faces.
