Lexisaurus is a cross between a game and a thesaurus! Expand your vocabulary by discussing, sorting, using and applying a range of similar words. In Lexisaurus, children must sort and discuss vocabulary. Not only is this a great way to get them thinking about words and their meanings, it also helps them to expand their verbal skills, by the very process of discussing the words. Children are then expected to use the words they have discussed to create a story or paragraph of writing, to show off their new-found skills.
