Chalk-A-Word

About Chalk-A-Word, from BoardGameGeek:

The more words you know the greater your chances. Use your letter cards to create new words or add to existing words in play. Spell as many words as you can and earn the most points before the chalkboard gets wiped clean. Using the letter cards in their hands, players take turns creating new words or adding to words already in the play area. Points are awarded for each letter used. In addition to Letter Cards, there are other cards that are wild or award special powers. The player with the most points at the end of the game wins. -description from the publisher
