The baggie in front showed what "100" looked like. I usually don't have such large quantities but I figured this was a special occasion!
To make it easy (and to save time for our kiddos and teachers,) I actually had the teachers names on the recoding sheet so kids could easily circle them.. It looked like this. (But precut, of, course!)
The winning guess was, I believe 405 or 605...I forget. But I do remember who won: a cutie from my class! She got to take home a huge bag of goldfish covered in Dr. Seuss ribbon and stickers.
It was so much fun that we're thinking of having a school-wide weekly estimation station next year. Since it's a small school, it should be easy to implement. Do you have an estimation station? Do you give out prizes to the winner? I've gone back and forth as to what I should do but have finally decided on letting the kids sign the Bravo Board. They LOVE it! I should take a pic and post it here. I'd love to hear how you implement yours.
