The Word List Generator Project has created a database of 2084 words that elementary school teachers can use to help students practice and build sounding out and word-form recognition skills
"The computer will randomly pick a term used in science. Discover the word the computer has picked by guessing which letters are in it. Each incorrect guess you make causes the atom man to decay. Solve the puzzle before the atom man completely decays!
Attention Teachers!! Add your own vocabulary words for your class to use!"
