One of our City Council members is speaking to a large group of 3rd graders this Friday and wants me, as a rep. of the planning dept., to come along and talk to the kiddies about planning in our city. Ugh! I've spoken to older kids about planning, but none that are this young. I don't have kids so I could really use some help (quickly, please!) with some ideas that will engage 100 or so 3rd graders for 45 minutes. Thanks in advance!!!!
