Young scholars create a scatter plot for bivariate data and find the trend  line to describe the correlation for the sports teams. For this scatter plot lesson, students analyze data, make predictions,and use observations about...

There are four irrational numbers that participants need to graph. Pi(π), -(½ x π), and √17 are easy to approximate with common rational numbers. On the other hand, the commentary describing the irrational number 2√2 is not...

Determine how close the line is to the scatter plot. Clear video instruction shows how to plot a scatter plot and find the best fit line using the linear regression function on a calculator. Pupils use the information from the calculator...

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

Here's a great lesson that looks at slope as an instantaneous change. Using an estimated tangent line, the presenter shows the class how to find an approximation for the instantaneous rate of change. Scholars determine the slope of the...

Learners build and program a car to drive a specific challenge distance.They must at the end of the lesson plan, have the car that stops the closest to a challenge distance.

What's in a name? Pupils create a data set from the number of letters in the names of classmates. Each group then takes the data and creates a visual representation, such as a histogram, circle graph, stem-and-leaf plot, etc.

Talk about technology in the classroom. This plan has all the resources needed to create a non-linear or branching story. Included is a step-by-step tutorial that walks middle schoolers through the project description, a model of a...

Here are a set of graphing lessons that have a real-world business focus.  Math skills include creating a scatter plot or line graph, fitting a line to a scatter plot, and making predictions. These lessons are aimed at an algebra 1...

Explore linear functions! In this Algebra I lesson, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

Students explore the concept of linear regression. In this linear regression lesson plan, students find the line of best fit for a set of data pertaining to a frog population. Students use their line of best fit to predict the frog...

Add more points on the graph ... and it still remains a line! The 13th installment in a series of 33 leads the class to the understanding that the graph of linear equation is a line. Pupils find several solutions to a two-variable linear...

Using the TI-Nspire calculator, statisicians identify outliers and their effect on the least-squares regression line. In finding the line of best fit, they determine what points will affect the least squares regressions and what points...

Young writers generate descriptive words. They use pictures of various landscapes (from books, magazines, or the Internet) and complete a story pyramid. The pyramid (included here) asks to describe the main character, the setting, and...

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The lesson also includes the discussion of slopes of parallel and...

Practice using linear models to answer a question of interest. The 12th installment of a 16-part module combines many of the skills from previous lessons. It has scholars draw scatter plots and trend lines, develop linear models, and...

Kevin Henkes has composed a series of books in which Lilly the mouse is a main character. Third graders use illustrations and key details as they compare and contrast the books, Lilly's Purple Plastic Purse and another...

Your birthday can be more than just about presents; it can even teach about absolute value. The class investigates absolute value as the distance from zero on a number line. Plotting birth months and comparing each birth month to July...

Learners investigate the relationship between perpendicular and parallel lines on a coordinate plane. In this geometry lesson, students differentiate lines based on their slopes.

For this analytic geometry worksheet, 9th graders graph and solve 13 different types of problems that include determining whether equations are linear to matching given equations to their corresponding equation in the second column....

Students explore statistics by completing a graphing activity. In this data analysis lesson, students define a list of mathematical vocabulary terms before unpacking a box of raisins. Students utilize the raisins to plot data on a line...

Learners examine sea surface temperatures to see how hurricanes get heat from the oceans surface.  In this hurricanes lesson students use the Internet to find data and make line plots. 

The battle of the sexes? Scholars first examine data on hurricane-related deaths and create graphical displays. They then use the data and displays to consider whether hurricanes with female names result in more deaths than hurricanes...

Use coordinate grid paper to plot points and identify shapes that are already plotted on the paper by saying their coordinates. Pupils also measure the distance between points and play the game Battleship. There are several web links and...
