Comments from Educators

Identify resources staff can use to develop relevant science curriculum

Brian A.

My students love CK-12's Braingenie, and I do too. This is my 2nd year using Braingenie, and I have helped several other teachers become acquainted with it too. I especially love that I can create the goals for my students and then track their progress through the reports.
