This guide builds on the curriculum developed by Karen Tanenbaum during her work at Intel. The guide also builds on activities and ideas from Leah Buechley, Mike Petrich, Jie Qi, Jay Silver, and Karen Wilkinson.

Other contributors include Mitchel Resnick, Jackie Gonzalez, and Clubhouse staff and mentors around the world. A special thank you to all of the Clubhouse youth throughout the Network who tested these activities and helped to make them even more engaging, meaningful, and fun.

Thanks also to Gail Breslow, Director of the Clubhouse Network, for supporting and guiding the development of this book and the Start Making! initiative.

Roger Stewart at Maker Media expertly guided the book from draft to completion, and Michelle Hlubinka of Maker Media provided valuable feedback along the way.

We are grateful for support from Intel, the LEGO Foundation, and the Lemann Foundation.
