I started out teaching the students to write the room in abc order with the first 2 worksheets printed out back to back. They would put it on a clipboard and walk around to find and write words. For a fun element I allowed them to use a marker to write the words.
Once they understood what they were doing I changed it up to writing 5 to 10 words on the ABC Order sheet depending on their ability. Then they would transfer those words to the second 1⁄2 sheet.
This is a great way to learn alphabetical order and have fun doing it!
