With two summers of babysitting money, Mia needs a way to compare her earning from both years. Show your learners that they can organize the data onto a double-line graph to easily compare which summer was more profitable. The lesson...

Explore how to graph lines from different pieces of information. Scholars learn to graph linear functions when given an equation, given two points that satisfy the function, and when given the initial value and rate of change. They solve...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

With so many types of graphs, don't let your learners get stuck figuring out which one to use. To track how Zoe spent her allowance, use this interactive lesson to review all the types of graphs and pick the best one to display the data....

Building on knowledge from the previous lesson, the second lesson in this unit teaches scholars to identify and interpret rate of change and initial value of a linear function in context. They investigate how slope expresses the...

Circles, lines, dots, boxes: graphs come in all shapes in sizes. Scholars learn how to make a bar graph using univariate data. They also analyze data using those bar graphs.

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

If only there was a graph to show the distance traveled over a period of time. Given distance-time graphs, pupils read them to determine the answers to questions. Using the distance and time on a straight line, scholars calculate the...

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...

Young mathematicians first graph a series of quadratic equations, and then investigate how various parts of the equation change the graph of the function in a predictable way.

Statistically, waste may become a problem in the future if people do not take action. Using their knowledge of statistics and data representation, pupils take a look at the idea of waste generation. The four-part unit has class members...

What do those points on the graph mean? The 10th instructional activity in a series of 22 presents proportional relationships as graphs. Class members interpret various points of the graph — including the origin — within the context of...

Activate the strengths of your visual learners using an informative lesson. In the 15th installment of the series of 28, pupils graph their solutions on number lines to create a visual representation of solutions. Problems presented as...

Consider the preponderance of evidence when making a verdict. The third of five lessons in Unit 1: The Big Climate Change Experiment focuses on the evidence for climate change. Learners study graphs, diagrams, and pictures regarding...

The bounce of a golf ball changes the result in golf, mini golf—and a great math activity. Scholars graph the height of golf ball bounces before finding a line of best fit. They analyze their own data and the results of others to better...

Is American growing fatter? Scholars begin with a mini lesson plan on reading charts and graphs using information about Human Body Fat in United States. They then transfer what they learned to charts and graphs using  harmful and...

Model situations with graphs. In the fourth installment of a 16-part module, scholars learn to qualitatively analyze graphs of piecewise linear functions in context. They learn to sketch graphs for different situations.

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...

The key is ... After a day of instruction on key features of graphs, groups create a poster and presentation on the key features of their given function graph. The resource provides an extension activity of "telephone" using...

Discover another way to interpret multiplication. Using an interactive, learners slide points (representing the factors of multiplication) along the x-axis of the graph of y = x^2 and observe changes in the line segment connecting the...

Do women with college degrees get married later? Using a provided scatter plot of the percentage of women who earn bachelor's degrees and the median age at which women first get married over time, pupils conduct a linear regression...

Writing an equation of a line is as easy as m and b. A activity presentation gives individuals different strategies for writing equations of lines. Some items provide a slope and a point while others provide two points. Whatever the...

Math modeling is made easy with the first installment of a 16-part module that teaches pupils to model real-world situations as linear relationships. They create graphs, tables of values, and equations given verbal descriptions.

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.
