I've been asked by a couple of people to teach an engineering / robotics class at our local co-op. I don't think they realized how much that might cost....or maybe they did...I'm super frugal so I'd never pay more than $40 for a co-op class..but robotics would be roughly $65 per student. Shoot, if we were to do the Lego robotics it's upwards of $400/robot! The $65 would give the kids each a robotic arm that they would build, and I'd teach them about the computer programming so they could program their robot to perform tasks. Does that seem too expensive or would you still sign your child up?
