When my son was learning to read, we played a game on paper. Starting with one word, each of us would change one letter, making a new word - starting with CAR, changing the R to a T makes the word CAT, and so on.NextWord is this game on the Palm.To accommodate players of varying abilities, NextWord is highly configurable2, 3, 4, and 5-letter words whether a player may reuse words whether they can reuse the last word they used whether they can reuse the last words other players used how many letters they may change how many letters they must change My son Daniel is allowed to reuse any words, and may change two letters of three-letter words. His sister Katherine, an accomplished third-grade reader, is only allowed to change one letter - and may reuse words, except for the most-recent word each player has used. Mommy and Daddy aren't allowed to reuse words at all.In addition, NextWord includes a “Speed Game” – where a single player plays against themselves, spelling words as rapidly as they can.Both my children have enjoyed watching NextWord develop, and keep asking to play it. I hope this enjoyment means a good game that you and your children will enjoy!
