Grab your favorite dictionary and play WordsWorth. As you play, you'll learn about permutations of words called reverses, palindromes, semordnilaps, and anagrams.

Assign a letter score to each letter in the alphabet, a through z, as follows: a = 1, b = 2, c = 3, and so on, up to z = 26. The WordsWorth of a word is the sum of the letter scores of the word's letters.

Most of the play in WordsWorth is thinking: knowing words, learning more words, and devising strategies for finding answers. People are well equipped to do this type of play. Some of the play is more mundane: looking up letter scores and adding them to get the WordsWorth of a word. First grade students might start with base-10 blocks as their WordsWorth calculator, and then move on to mental math and paper and pencil math as their addition skills improve by playing WordsWorth.
