The Phonics Game and The Math Game

I've used The Phonics Game many times with 1st and 2nd grade learners and it works really well, especially in small groups of about 4-5. I have never used The Math Game or The Vocabulary Game but I ssume they are similarly effective. In case you are unfamiliar, it The Phonics Game is described as "a total phonetic reading system, cleverly disguised as a series of fun, interactive games" and it truly works. It has a variety of difficulty levels and is useful at home as well as the classroom.
