I use the overhead to have students arrange words into sentences and sentences into paragraphs. I type the words on the computer using a large font, print them on a transparency and then cut up the sentences. When students are able to move the words around on the overhead and the class can see what's going on, they pay attention. Sentence strips can be used in the same manner. To modify for younger students, one could use letters to make words or show a picture and have the students give the correct word.
