As the teacher, I will supply the information needed for class.  I will be using Kahn Academy's resources on Algebra and point the learners to specific videos and practice problems on that page. As a teacher who has done this many times before, I can tell you that using a web resource in place of a textbook far-better prepares a student for his/her future academic and professional career. 
 In college and the real world, nowadays, information is readily available if someone knows how to access it. All of the same information that is in textbooks are now available on credible free websites.

Students should also have a pencil,  and graph paper. Calculator is needed for this class.

This course is not for the student just being introduce to linear equations and linear graphs.

Parents should make sure their learners are ready to dig deep into linear Algebra word problems.  The course assumes they have strong foundational skills in plotting graphs using slope, intercept, variables, coefficients, ordered pairs, point-slope formula, standard formula, slope intercept form, perpendicular slope, and all other basic constructs of a linear plot.  In addition, the student should have a strong grasp of basic pre-algebra skiils including:
1) Real Numbers, Variables & Expressions 
2) Order of Operations 
3) Properties of Numbers
4) Distributive Properties 
5) Adding & subtracting polynomials 

So if your student is at an Algebra 1 level and already has a handle on those skills that teachers reinforce at the start of the year, but wants to dig deep and MASTER linear algebra, this is the course for them.
