Call a group of students up to the front of the room. The number of students will vary with the number of words in the sentence. Give each student a word card. At first, have only a few students stand at the front of the room and make an incomplete sentence. Discuss what makes that sentence incomplete. Then have the rest of the group join in. They must make the sentence complete by standing in order. I like to have them do this activity without talking. Then make a new group with new students and repeat the process.
