Find a mistake by Wendy (Brooklyn, NYC)  4 Stars
October 04, 2009
Hi Guys,
This clock is a hit with the kids.
The answer to hour 4 is debatable.
50/2=100/X, x=4 true, 100/4=25. the four on a clock represents 20 minutes not 25 minutes.
Perhaps this may work better... 50/12.5=100/X, x=25, 100/25 =4
Your students might be challenged to find alternative equations to satisify both the hour and the minute aspects of the clock.
The quality is good, smooth finish, intriguing appearance.
Many people stop to just look at it.
Have fun.

Classroom Clock by reg (Houston)  5 Stars
October 06, 2008
As a former math teacher, I was drawn to this clock! I have purchased it for a former co-worker, who is also a friend, for Christmas. It should be a hit in his room. I was impressed with how quickly this arrived. I ordered Tuesday night and received it before noon on Friday. Since it didn't qualify for Prime, I'm glad it arrived quickly so I feel I got something for having to pay for shipping!
