Counting Seeds

Counting seeds involves a lot of work.  First we made referent piles of seeds (e.g., 10, 20, 25) and then we estimated how many seeds we had in our pumpkins.  After getting our estimates, we actually grouped our seeds in numbers that we could all skip count by in order to get an accurate count.  As you can see, some of the groups got quite sophisticated and kept their groups of seeds organized by using rulers as boundaries.  A lot of negotiating and cooperating go into counting hundreds of seeds.
