First, we estimated the circumference of our pumpkin. We started by letting one of the kids pull the yarn for her guess. Then, we put it around the pumpkin to see if it was too short or too long. It was a little too long, so we talked about making a good guess based off of what her string looked like.

|Clearly, this chart was made a LONG time ago (before I became obsessed with fonts), but it works well for comparing our yarn estimates.|
The next thing we did was estimate the weight of our pumpkin. We had a little mini lesson on weight and talked about things that weighted more and less than each other before we made our guesses. We passed our pumpkin around so we could get a really good feel for it, then made our guess. After lunch, we took our pumpkin to the office to borrow our secretary's scale...our pumpkin weighed 3 pounds!
|The boys liked it more than the girls!|
