A lively song guides you through a hot air balloon adventure, where altitude follows a clear math rule: height equals time multiplied by three (e.g., 3 meters at 1 minute, 9 meters at 3 minutes). It shifts to a function machine, where outputs like 9 correspond to inputs like 3, revealing the inverse rule: divide the output by three to find the input. With a rhythmic chant, it emphasizes identifying input-output patterns, testing guesses, and mastering the multiplication and division rules with c
