First LEGO League

First LEGO League is a fantastic international robotics and research project competition where students “develop critical-thinking and team-building skills, build STEM self-confidence, and gain valuable perspective on the importance of failure in the learning process.” (More information)

Parental involvement and contribution is expected, and an in-person interview is required – we want to have a great experience for everyone.

We will start our first meeting on Friday, Sept 13 from 310pm-415pm and will meet weekly through January or February when the state-wide competitions begin.
