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.

Sad pumpkins

Halloween decorations!  All moldy and sad!  A

super science experiment too!

Pumpkin Math

Pumpkins were a big theme this past week in math.  First we read this wonderful book which taught us all some very interesting things about pumpkins.  Did you know that the more lines in your pumpkin, the more seeds it will have?  I had 5 pumpkins for the kids to work with in small groups. Their job was to do some measuring before they thought about carving their pumpkins, which was clearly their first priority!
