This program teaches students to make words from letters and then to make sentences from words. The student first sees the letters of a word in their correct order. The student then moves the letters into spaces provided to form the word. The student next sees the letters “scrambled,” i.e. in random disorder. The student then puts the letters in order in the spaces provided to form the word. After that, the student sees scrambled letters with distracters, and must choose correct letter in the correct order to make the word. It is basically an grammar dictionary that will check your work for you! And you get the convenience of being able to carry it with you all the time. Don't turn in that paper to your instructor until you've run grammar checker and fixed any little errors. Use it on your emails, so that your boss is impressed with your writing ability. Thanks By, K&P Team
