Right now we have Interactive Science K-8 and before you dismiss selling the current list programs with new standards coming out think about this - NOBODY is going to "flip a switch" and start implementing the NGSS in their classrooms all at once. Regardless of what is said by customers, what is promised by superintendents, and what is expected in schools, the methods of instruction, classroom set up, and the switch to activity based learning simply can't happen overnight. Customers need a transitional strategy - Interactivce Science is a phenomenal solution as it is correlated to the NGSS, hits a home run on all of the Common Core Literacy standards, and has plenty of hands on and activity based options for customers.
