That is one of their fun suggestions for the 100day ant magnets you can get cheap from them (50 black/50 red). We are all so busy especially at the beg. of the year, I wanted something simple where they could read their name and connect with me.
My last team partner makes double name tags, laminates library cards to a poster and velcros one set of names!! TOO MUCH WORK every year (and wastes recources) save them for something else
I make ONE roster with all my kids. Alpha order-the last few are added to the bottom out of order since I did get a few more. I set it up after the first few weeks since we use real roll calls sent to the office during that time.
THey get an ant from me, find their name and cover it. We also do a quick math subtraction with how many ants I have leftt vs how many kids in our class.
