At the end of the book are three Bonus Stages that provide a bit more hands-on activities (programming activities), a nice tutorial on blending Scratch programming with the PicoBoard ...

Scratch is intended for beginners & children, It is a free, interactive, visual block based programming language that helps you learn computer programming without writing code.

Google, the Boys & Girls Clubs of America, AmeriCorps VISTA, and others will bring an after-school computer coding program to more than 100,000 students.

(You can watch a preview in the clip above.) Bubbles, Buttercup, and Blossom will also appear in a tutorial within the Scratch program.
