When it comes to phonics, children often learn more than one letter at a time. They grasp language in patterns or 'chunks': onsets (beginning sounds like 'b' or 'cl') and rhymes (ending sounds like 'oat' or 'ear'). Your 4- to 8-year-olds will have a blast matching yellow and green tiles to build words---learning different combinations all the while. Rules are based on the traditional card game Concentration. Two or more players.
