Smallest to Largest Name the smallest things that you can think of. Obama’s brain excluded… What are some of the largest things you can think of? Federal deficit excluded… What about the most distant object?

Distance Tabs On your desk there is an envelope marked with ‘A’ or ‘B’ & a #; with pieces of paper. Open the envelope, please… In your group - place these in order on your table; small to large Small on left, large on right GUESSSome you won’t know; GUESS! GO!

Distance Tabs Now, collaborate with your CONTERPART group Each group updates tabs in order with your partner group (A1 & A2…) Report and record. Now, collab with a MEGA-GROUP (OTHER A’S…) reviews and edits. Discussion & review.
