CK-12's Algebra offering (via website or Chrome app) is a set of well-organized resources you can use to supplement your curriculum. Resources include reading passages, pre- and post-read activities, assessments, videos, study aids, and web links, all of which can help in catering to students with different learning styles and abilities. The topics covered include Graphs and Functions, Rational Expressions, Matrices, Linear Equations, Polynomials, and Factoring, just to name a few. All topics are further broken down into subtopics, which makes it easy to find just the right resource for almost any algebra concept you're teaching.
Keep an eye out for the Read activities -- have students complete these to help reinforce concepts from your own lessons. You can assign them as individual reading, but it might be helpful to do the Guided Practice problems as a class. The videos are best used for whole-class instruction, where you can pause to give details and address areas of potential confusion. Use the assessments as post-lesson resources to gauge kids' learning, and offer them extra practice as needed.Continue reading Show less
Key Standards Supported
Expressions And Equations
Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
Solve linear equations in one variable.
Use the process of factoring and completing the square in a quadratic function to show zeros, extreme values, and symmetry of the graph, and interpret these in terms of a context.
Reasoning With Equations And Inequalities
Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
The Number System
Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.
Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.
