Card Sort Your table will be given an envelope full of numbered cards. Put these cards into groups in the best way you see fit. Be prepared to justify WHY you sorted them the way you did.

Gallery Walk You will each receive 2 sticky notes. Title one “I notice…” and the other “I wonder…” Walk around and look at the way each table sorted their cards. Respond to any table with each of your sticky notes.
