The town of Prosaic was a dull, boring place. That was until a group of aliens, led by Greg Arious, arrived with a special gift." 'Greg Arious and the Lexicons' has been designed to help teachers introduce the concept of synonyms and to demonstrate the use of a thesaurus to Key Stage 2 (ages 7 - 11) children. It can also be used as a focus when looking at lots of other topics including different types of words (nouns, verbs, adjectives), antonyms (opposites), dialogue words and onomatopoeia.
