Develop another way to find the equation of a line. The lesson introduces the procedure to find the equation of a line given two points on the line. Pupils determine the two points from the graph of the line.

This lesson introduces the idea of slope and defines it as a numerical measurement of the steepness of a line. Pupils then use the definition to compare lines, find positive and negative slopes, and notice their definition holds for...

They appear to be different, yet they are the same line. Part 24 out of 33 lessons provides a theorem about the relationships of coefficients of equivalent linear equations. Pupils use the theorem to determine whether two equations are...

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...

Scholars connect slope-intercept form and standard form to the values of m and b by first matching a set of cards that have slope-intercept form, standard form, values of m, values of b, and graphs of linear equations. They then...

Functions have families, too. Learners first graph the parent functions for linear, quadratic, and cubic functions, and then use vertical translations to graph families of functions.

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...

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...

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...

Step up to learn about step functions. The lesson, designed for high schoolers, first covers piecewise functions and how to draw their graphs. It then introduces step functions, including the greatest integer (floor) and...

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...

Individuals learn how to plot rational numbers on the number line in the sixth lesson of a 21-part module. They identify appropriate units and determine opposites of rational numbers.

Before graphing and finding distances, learners investigate the coordinate plane and look at patterns related to plotted points. Points are plotted and the goal is to look at the horizontal and vertical distances between coordinates and...

Do you need to graph lines to see the point? A thorough lesson plan provides comprehensive instruction focused on solving systems of equations by graphing. Resources include guided practice worksheet, skill practice worksheet,...

Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

You can't see patterns in a jumble of numbers ... so organize them! Learners take a set of data and use a line plot to organize the numbers. From the line plot, they find minimum, maximum, mean, and make other conclusions about the...

Young mathematicians write equations of lines in this algebra activity. They solve linear equations into the slope intercept form. Next, they graph the lines using the slope and the y-intercept, and they write equations for the lines...

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...

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.

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

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

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.
