After everyone has an opportunity to complete the worksheet (I let them do it with their center partner--but they each have to do a recording sheet) we then go over it as a class. The challenge for the class is to figure out which item was the heaviest in the basket. the debate among them was fun. For some of them, it was the realization that just because an object was the largest in the basket, it didn't mean it was the heaviest.
So they liked it so much, they talked me into making another one. So when you download it, you get 2 versions. Click HERE for the Freebie. Enjoy!
