Hehehe no, well maybe....just kidding :) The 'in' thing right now in 4th and 5th grade is to have marbles. All the schools seem to be like this. The bad part is they want to play it all the time in class. My rule as a sub (and generally the teacher's rule too) is that they can have them as long as they only play with them at recess. If it happens in class, then I get to 'have' them. I just have a baggy and collect them and put them in the teacher's desk and write the student's name on it.
Well it didn't take too long for me to get a collection going...and all from one kid lol. You think after he lost his best marble to me he'd learn. It's called a cookie because of the bits of glass in it looks like crumbs. I also happen to have one and took a pic
