Task 1: BAGGIES Open the baggie and remove the items Open the baggie and remove the items You have FIVE minutes – Timekeeper, Leader, be alert! You have FIVE minutes – Timekeeper, Leader, be alert! Sort them into groups Sort them into groups –It is up to your team how many groups you create –It is up to your team how you determine the traits for a given group –SCRIBE: on your team’s paper, write #1, and then write down or draw a quick list or diagram showing how your team sorted the items

Share Out Speakers: How did your team decide on the groups? What traits did you use to sort things out? How many groups did you create? Speakers: How did your team decide on the groups? What traits did you use to sort things out? How many groups did you create?
