LearnZillion's Algebra module is a collection of video lessons that cover a generous portion of the algebra Common Core math standards. Although not all standards are addressed, the alignment is tight, especially for Algebra I courses. Lessons offer detailed examples with animated diagrams to help students develop a solid understanding of key algebra skills. Lessons that cover standards A.REI.3, A.REI.4B, and A.REI.5 include supplemental lesson commentaries and guided practice problems.
These video lessons are an excellent way to reinforce classroom instruction. After introducing a topic use the Assign tool to give kids lessons and videos -- have them work in small groups. Make sure they take notes, and encourage them to pause the videos as needed. Later, discuss the example problems as a whole class. For an assessment, you can ask kids to collaborate and develop their own problems -- exemplars they could present to the class.

Reasoning With Equations And Inequalities
Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
Solve quadratic equations by inspection (e.g., for x2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.
