Who's First?

Nifty huh?  But what is it?  Glad you asked.... Little numbered flags so that when my kids have a question with their school work and I'm busy with someone/something else, they can grab a flag and keep working on something independently.  Then when I come back to the table I can see at a glance who is first, second, and so on. 

I got the idea from this book.  (Great read btw.) 

I made them with skewers stabbed into playdoh tubs.  We've used these for a couple of weeks now and it's working wonderfully.
