Don, while writing a 48G program to to discrete timedomain convolution , I realized that Polynomial Multiplication was the exact same process.
Perhaps if you tell them they are doing CollegeLevel EE work, they will feel more proud. It is easier to visualize anyway when you look at the signal functions anyway instead of formulas.
Reverse the second signal and then shift from the left, multiply and add. For example:
Discrete Signals: 


 
 
 
   
   
  conv.   =   
  
x + 3 x + 3 x^2+ 6x +9
