Our Adventures With Robotics: The Lego Mindstorm Kit [Wired: GeekMom]
Lego’s Life of George Takes Building to the Smartphone [Wired: GeekDad] - This awesome augmented reality app utilizes Legos and smartphones to challenge young kids to use their spatial reasoning skills (among others).
LEGO.com Architecture Home - Lego has created a series of detailed, rich models of actual architecture. These sets will give block-loving children a real world connection to STEM (not to mention history).The LEGO Ideas Book - Great book to inspire older students or those up to a challenge!
BONUS: For more on Legos (among other topics), read August's Weekend Reader on Robotics in Education. I also included Legos on my list of Toys & Games Every Kid Should Play With Growing Up.
