My students have to sign in on a dry erase board as one of their jobs when they arrive each day. I have an easel dry erase board set up with magnets that have the numbers 1 through 18. (I bought counters and hot glued magnets onto the back of them. Then I wrote a number on each one. I wish I had a picture...) The students find their number and sign in next to it. I start out by just having them sign in with their first name. After a couple weeks when they are used to that routine, I switch it to signing in with their last names, then first and last names and eventually they sign in with their middle names too. As the year goes on, I switch the sing in skill. I have had students sign in with their phone numbers, street addresses and even their birthdays. The students LOVE signing in and it's a great way for them to practice their names, address, phone number and birthday just to name a few!
