You can keep the 'first day of school ideas' firmly at the back of your mind, because I have something ready for you!
Copy one of these pages for each of your students. Once completed (they write info about themselves and draw a picture), shuffle them and place them in a face down stack. Choose students to take a paper from the top of the stack, turn it over and read it to the class.
The rest of the class guess who the student is by listening to the clues read.
{Note: For the 'I am...' section, have students write something other than their name}
Once this activity is completed students can add their name to their poster and display it on a bulletin board or collate them into a class book.
For added fun, fill one out yourself as the teacher!
