Users explore number patterns and develop algebraic thinking based on spatial relationships with this interactive Java applet. Users choose a table which seats 4 or 6 persons and which are set in a straight line or rectangular arrangement. The number of tables in the chosen arrangement may also be adjusted, encouraging users to explore resulting number patterns for the total number of chairs. An "exploration" mode outputs the number of chairs as the parameters are adjusted, whereas a "guess" mode requires the user to determine the number of chairs for a chosen configuration.
