Students in a college algebra class use graphs to solve inequalities. Using the coordinate graphing system, they represent the relationship between x and y intercepts. They practice solving equations with complex numbers and locate...

Fifth graders explore the math concept of graphing integers. In this graphing integers lesson, 5th graders examine visual examples. Students also practice solving problems that their instructors model.

Students explore the concept of graphing stations.  In this graphing stations lesson, students head to various teacher set-up stations involving slope, point-slope, standard form, parallel lines, etc.  Students work problems at...

Students work to complete various algebraic equations using different methods. Given a word problem, students create a poster identifying the various parts of the equation as well as the solution to the problem. Posters are presented...

Explore slope using geometric patterns. Young mathematicians investigate towers built from cubes to develop a linear pattern. They move the data to a coordinate plane to connect the pattern to slopes.

Young mathematicians explore transformations of graphs by graphing sets of functions on the same pair of axes. They use their graphs to determine the effect that the values of a and b in y = ax + b have on the graph of y = x.

Domain to a math teacher makes perfect sense, but it can seem like gibberish to high schoolers. As it is laid out in clear terms, domain is introduced and explained among all types of functions throughout the handout. The first three...

In this online math activity, students solve systems of equations by using addition and subtraction . This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific...

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,...

Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.

Class members create a table of the number of chords that can be drawn given the number of points on a circle. Pupils analyze the data created, find a function to fit to it, and use the function to make further predictions.

You can't go wrong with a lesson that involves candy! Learners solve and graph one-variable inequalities and use candy to graph the solution. Individuals associate open circle graphs with life savers and closed circle graphs with round...

Collaborative groups utilize their knowledge of parent functions and transformations to determine the equations associated with graphs. The graph is then related to the scenario it represents. 

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

What are terms, factors, and coefficients? This slideshow provides definitions and examples of various parts of algebraic expressions, and provides guided practice problems in writing and identifying parts of algebraic expressions for...

Sixth graders complete worksheets and make journal entries to interpret mathematical expressions about the pyramids. In this equality by balancing equations lesson plan, 6th graders participate in groups or by themselves to complete...

Students discover for which kind of linear function is appropriate to use the "scatter" or the "connected" term. In this lesson, students investigate functions using variables, patterns book, graph paper, rulers and the graphit program.

In this systems of equations practice worksheet, students use their problem solving skills to solve 24 problems.

An engaging, and not to mention attractive, lesson plan has prealgebra and beginning algebra scholars examining linear relationships. They consider the rising water level as a swimming pool is being filled. They do so by charting and...

Ninth graders solve multi-step equations.  In this Algebra I lesson, watch a video on solving equations with variables on both sides of the equal sign.  Students visit an Internet site to solve simple equations through the use...

Students read real world problems, determine the variables, and set up the function using algebraic statements. After entering data into the graphing calculator, they display information in the form of graphs and scatter plots. ...

Students graph linear equations using intercepts, find y-intercept, find x-intercepts and graph linear equations that use horizontal and vertical lines.

Students are introduced to the basic ideas needed for understanding linear functions.

Students solve systems of equations. In this algebra instructional activity, students identify the domain and range of each function. They use the slope and y-intercept to graph each line.
