I, too , use a sign in/sign out method. The kids show me a sign language sign to ask to go to the bathroom (that way they don't verbally interrupt as I teach, others are working, etc.), and I nod my head if it is an alright time for them to go. They then sign out in a small book and sign back in when they come back. They have to read the analog clock to write down the time they leave and the time they come back - this gives them time telling practice. It also helps to know who was in the bathroom at what time if there was an "incident," which seem to happen in school bathrooms! It is also the Calendar Person's job to enter the date every morning in the bathroom log.
