This lesson introduces the notion of a system of inequalities and demonstrates how to graph such a system.
Editable PPT on how to set up a system of equations in context.
In this Khan video, students will learn how to logically set up a system of equations.
This is a Khan video with Graphical Systems Application Problem.
Class project with rubric writing and using systems of equations.
Article on how to solve systems of equations by elimination and multiplication.
Students solve a system of inequalities by using what they learned in the previous two lessons and apply their new knowledge to some real-world linear programming-type situations.
This video explains what the words term, factor, and coefficient mean. Think of an expression as a sentence. A sentence has parts, and so does an algebraic expression.
This task has a couple of aspects designed to encourage students to attend to the structure of the equation and the meaning of the variables in it. By focusing on different variables in parts (a) and (b), it fosters flexibility in seeing the same equation in two different ways: first as an equation in t with constants v and d, then as an equation in v with constants t and d.
Texas Instruments activity that describes functions and the effect of transformations on domain an range; requires TI-83/84 technology.

This classroom task is meant to elicit a variety of different methods of solving a quadratic equation.
Here's a nifty word problem in which we find the dimensions of a garden given only the perimeter.
Practice worksheet on two step word problems.
This video introduces two variable linear equations.
Texas Instruments directions to finding intersection of two equations;REQUIRES TI technology
The purpose of this task is to deepen student understanding of the standard deviation as a measure of variability in a data distribution. The task is conceptual rather than computational and does not require students to calculate the standard deviation.
The goal of this task is to represent an exponential relationship by an equation and identify, using knowledge of the context and the structure of the equation, possible graphs for the equation.
