Each set contains 12 beautiful hardwood triangular prisms, identifiable by colour coded musical notes which only appear on one end of the block, so they can be turned upside-down to test the user's discriminatory skills. Each colour coded sound prism makes a different sound when shaken (identical coloured pairs make the same sound). Used to encourage students to use their listening skills, an important precursor to early phonics. Size of triangular prism 50mm x 60mm.
