Read and Match Dominoes are self-correcting. This will allow the game to be played without adult supervision. The dominoes are designed for young readers who can both recognise common sight words and form words as they sound and blend single sounds. The wipe clean dominoes 95mm x 40mm, are printed using bright non-toxic inks. They are supplied, complete with instructions, in a strong plastic storage box. This game can be used as an individual activity or played in a similar manner to traditional dominoes by 2-6 children
