Ten different wooden cylinders with tactile surfaces and an accompanying solid wood board with the same reliefs.
The tactile contrasts (differences in touch perception) are clear. The color contrasts are also clear, which is attractive to all children, and extra useful for the visually impaired. The colors also repeat on the board, which provides extra visual support.
Initially with open eyes, later possibly blindfolded, your child can place the cylinders one by one in the correct place on the board.
For the visually impaired and blind, this version is the best to start with.
A fun game can also be played with several children.
The pieces and the board are beautifully finished and varnished.
