Play a board game:
Place the board in the center of the table. Go around the table-- each person can roll a die to move the game piece that number of spaces and answer the corresponding question. Questions can include things like “What was your earliest Passover memory?” “Which character in the haggadah do you identify with and why?” “Act out something from the haggadah”.
This is a fun way to engage everyone at the table, including the children. You can include "question" categories that are both serious and personal, as well as fun and silly.
