What is this? Ok I get it... But WHY do I need it?

So last week I ordered some pencils for my kids. I've decided for a long time now that at every holiday/special day that we "celebrate" in our class the kids gift from me will either be a pencil or a book or both. They don't need anything else plus 7 year olds EAT pencils. (How else could we go through so many every week?)

I usually try and buy the pencils at walmart because they're $3.50. I couldn't find any st. Patrick's Day Pencils though plus we have Dr. Suess week next week. So I got on Smilemakers.com because I had a $10 off coupon (I try to only ever buy anything if I have a coupon or it's on sale.)

One thing funny about Smile Makers is that they send out a few samples of their items with your order so they can try and get you to buy more stuff...The following are picture of one of the items I got in use (and yes I didn't know what it was until I read the directions!)

So I'm ready for it... Why would a teacher (who if they're anything like me spend most of the day TEACHING) need this?

Any creative ideas for how I can use it? Or maybe you would like it? I can't wait to hear your ideas...
