I was wondering if anyone had some ideas... I am finishing our explorer unit by having an "explorer day." I want to do something fun that the kids will remember for a culminating activity. We just studied Columbus, Erickson, Marco Polo, Dias, and DeGama. So far, I'm going to tape off a section of the room for our "ship" and the kids can't leave it because we are sailing. We are going to write letters in bottle about how it's on the ship and switch them with another class. I was also going to have biscuits as a snack. Does anyone have any other fun ideas?? Thanks so much!!
