The Graded Rough Tablets material promotes development of the tactile senses by matching a series of sandpaper-covered tablets.  The set includes ten wooden tablets in five matching pairs, with different grades of sandpaper attached to one side of each tablet.  The student is expected to identify the correct matching pairs and arrange them from either finer to coarser grit or vice-versa.

• 10 wooden tablets in 5 matching pairs
• Sandpaper roughness ranges from fine to very coarse
• Tablets measure 13 cm x 9 cm (about 5" x 3.5")
