In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

This fourth of twelve units in a series continues the investigation of functions through equations and inequalities. However, the modular nature of the lessons in the section make this an excellent resource for any curriculum...

This first of twelve algebra 2 resources provides a broad review of many algebra 1 concepts through a number of separable lessons and labs. Starting with the real number system and its subsystems, the sections quickly but thoroughly...

Graphing all kinds of situations in one and two variables is the focus of this detailed unit of daily lessons, teaching notes, and assessments. Learners start with piece-wise functions and work their way through setting up and solving...

Time to study the most sensible function — rational functions! The seven-lesson unit develops the concept of a rational function through a connection to rational numbers and fractions. Scholars graph functions, solve equations, and...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

This fabulous resource is a must-have for any algebra teacher's arsenal of lessons. Developing the idea of equations and use of variables from basic physical scenarios, learners gain valuable intuition in the structure and meaning of...

An informative module highlights eight polynomial concepts. Learners work with polynomial functions, expressions, and equations through graphing, simplifying, and solving. 

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

Your learners explore growing patterns by describing, extending, creating, and evaluating practical pattern problems in this three-day collaborative unit. Beginning with concrete patterns and function tables to extend and...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

Practice evaluating expressions in two variables by plugging in values for the variables. These problems include some fractions and decimals. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch...

Practice evaluating expressions in two variables by plugging in values for the variables. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] Evaluate multi-variable expressions by using a given value for the variable.

Practice plugging in a value for the variable in an equation. These are introductory problems, so the expressions aren't too complicated. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

Practice writing slightly more complex algebraic expressions to model real-world situations. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

Learn how to solve and explain two-step equations using whole numbers and inverse operations. Complete the lessons and practice activity and then play the interactive games to test your skills.

Practice spotting the mistake in someone else's work as they attempt to solve two-step equations. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice solving equations that take two steps to solve. These problems involve arithmetic with fractions and decimals. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive...

Practice problems where the goal is to find the mistake in two-step equations.
