I retired from Handley on June 2, 2006 and will not update the Problem of the Week page.

However, I have started a Problem of the Month page and it can be found at:
Problem of the Month  

Thanks to all who have sent in your answers over the years -- it's been great!   I have posted a "Problem of the Week" every week in my classroom since September 1968, and I have posted one on the internet since March 1998.   So, this is going to leave a void in my life.
