Robotic Residencies can happen any time in the school year. It works best if you plan for two classes to split a morning or afternoon. Plan for between 5 - 8 visits for a solid robotics working experience.
When booking for Robotics Residencies, try not to request multiple days in a row. A Monday / Wednesday, or a Tuesday / Thursday pattern with breaks in between robotic times works much better than a solid week particularly with younger students. Contact me if you need help with scheduling.
Be sure the robots are assembled and the batteries are charged before our first time together. If you have just bought the robots, check out the podcast, Getting Started With New NXT Kits.
