Pupils work through a guided activity on fitting a linear equation to a set of data by entering the data into a calculator and trying to envision a line of best fit. They then have the calculator determine the least-squares line and...

Represent linear equations in both two and three dimensions using parametric equations. Learners write parametric equations for linear equations in both two and three variables. They graph and convert the parametric equations to...

Computers are useful for more than just surfing the Internet. Pupils first investigate scatter plots and estimate correlation coefficients. Next, they use Microsoft Excel to create scatter plots and determine correlation...

You may be able to see patterns visually, but mathematics quantifies them. Here learners find correlation in scatterplots and write equations to represent that relationship. They fit a line to the data, find two points on the line, and...

Determine the slope when the unit rate is difficult to see. The 17th part of a 33-part series presents a situation that calls for a method to calculate the slope for any two points. It provides examples when the slope is hard to...

Don't give your classes the third degree. Use radians instead! While working with degrees, learners find that they are not efficient and explore radians as an alternative. They convert between the two measures and use radians with the...

As a middle school assessment task, learners first examine line graphs of monthly temperatures for two locations, and then match box plots to each line plot.

Educate your class about blood alcohol levels by combining health with math practice. Class members read a little bit about blood alcohol concentration and then solve some problems related to determining alcohol levels and alcohol...

Work on graphing linear equations using the provided materials. The print and video lesson thoroughly review the concepts related to graphing linear equations in slope-intercept and standard form. The materials prepare learners for...

Practice finding the equation of a line with this algebra lesson. Middle schoolers are given a pair of coordinate points representing two points and are asked to write the equation of a line. Then, they are given an equation and asked to...

Turn your classroom into a local cell phone store. Then, have your cell phone agents use linear equations to visually display three cell plans and their advantages. It makes for a great group project. Discuss how to decide which plan is...

Learners design questions that can be answered by collecting data. In this line-plot lesson, pupils collect data and graph on a line plot on world records. An abundant supply of teacher support is provided in this resource.

Students write a journal exercise that relates to pets. They collect information from each other in order to practice making and interpreting bar graphs. They Continue building different kinds of graphs with the group.

Students graph inequalities and solve the equations. In this algebra lesson plan, students graph their solutions on a number line and create an inequality for a word problem.

Fifth graders interpret data into graphs and percentages.  In this organizing data lesson, 5th graders discuss bar, circle and line graphs.  Students complete bar graph and apply probability using the results.

In this quadratic inequalities worksheet, 9th graders solve and graph 10 different problems that include various forms of inequalities. First, they solve each equation shown algebraically. Then, students state the solution set of the...

Students identify real graphs and misleading graphs. In this algebra lesson plan, students surf the Internet for real life scenarios where graphs are used in a misleading way as well as in a correct way.

In this statistics worksheet, students examine and interpret pictographs and line graphs. Students analyze the provided data in order to create bar graphs, circle graphs, and box and whisker plots. The nine page worksheet accompanies a...

Students use commercial software to organize and visually display data to draw conclusions; students use graphing software to create several types of graphs illustrating the number of each color of M&M's in one bag.

In this straight line graph worksheet, students identify linear equations.  They plot points of given problems.  This one-page worksheet contains 3 problems.

Eighth graders graph solutions to problems on a number line. After discussing algebraic expressions, 8th graders discuss how to solve them using an inequality. They observe examples and then work problems at their desks and on the...

Seventh graders review different types of graphs such as bar graphs, line graphs, box & whisker plots. As a class, they read a story and construct graphs to solve the data in the story. Students play "Graph Jeopardy" which requires...

Plot data using the number line and discuss how negative numbers are used in math and science. Sixth and seventh graders share their graph with the class and provide an explanation for their plotting.

In this graphing lines learning exercise, students graph 28 lines given various data.  Students graph lines given two points, a point and slope, and a line perpendicular or parallel to a point.
