Braingenie is a free service offered by the CK-12 Foundation. Braingenie provides online math and science practice activities for elementary, middle, and high school students. Braingenie’s library of activities is divided into nine sections and many subsections. The nine sections are 1-8 Math, Brain Math, Algebra I, Algebra II, Precalculus, 6-8 Science, Biology, Chemistry, and Physics.

Students can use Braingenie independently by simply going to the site and clicking on the “learn and practice” button. Students can use any and all of the practice activities without having to register on the site. Students who do create Braingenie accounts can save their progress and their scores. Registered users can also have their top scores appear on the leader board for each practice activity.

Braingenie can also be used by students as part of class accounts created by their teachers. Teachers can register on Braingenie to create a classroom account. Teachers are able to generate accounts on behalf of their students and even manage students’ passwords. That’s a great option for elementary school and middle school teachers. Teachers who create classes on Braingenie can set class goals and give their students specific practice activities to work toward reaching those goals.

Like most online practice services, Braingenie isn’t a replacement for your own instruction. Braingenie offers instructional videos for students to watch before diving into each set of practice activities. This makes Braingenie a good complement to your instruction as a place for students to refresh their knowledge and practice their skills.
