Easy to implement while still meeting academic standards.


Apply physical science concepts, engage in scientific inquiry, and perform data analysis.


Create and test programs in projects combining hardware and software with variables, loops, and conditionals.


Collaborate, communicate, and create innovative designs using the Engineering Design Process.


Reason abstractly while solving multi-step real world problems and algorithms.

A lot of teachers have a hesitation with getting out of their comfort zone. When you are talking coding, you are talking a foreign language. That hurdle has been taken down. It was to a point to where teachers could learn easily with the students. It has helped with knowledge transfer and has become something they can do themselves.”
– Mike Bell, Digital Learning Coach, Floyd County Schools
