Beginning in 1851, Thoreau recorded the dates of the first spring blooms in Concord, and this data is helping scientists analyze climate change! The culminating instructional activity in the series of four has pupils graph and analyze...

The next time you read a magazine or watch the news, make note of how many graphs you see because they are everywhere! Here, scholars collect, enter, and graph data using computers. The graphs are then analyzed to aid in discussion of...

Can two lines intersect at more than one point? Using yarn, create two lines on the floor of the classroom to find out. Cooperative groups work through the process of solving systems of equations using task cards and three different...

Fly through graphing functions with the Function Flyer. Young mathematicians use an interactive to graph different types of functions. A set of exploration questions has users investigate patterns in functions.

Two-variable equations can express a constant rate situation. The lesson presents several constant rate problems. Pupils use the stated constant rate to create a linear equation, find values in a table, and graph the points. The resource...

Create an understanding of solving problems that require more than one equation. The lesson introduces the concept of systems of linear equations by using a familiar situation of constant rate problems. Pupils compare the graphs of...

Use a graph to tell a story! Given a graph, young scientists create a story to match. They must provide their own axes labels and description of the scenario. The graph has increasing, decreasing, and constant sections.

Represent the ups and downs of a bank account. The two-part task points out that some types of graphs may better show discrete functions than others. Pupils analyze a graph on how well it represents the situation. They develop their own...

No graphing calculator? No worries, there's an app for that! Young mathematicians use an app to graph functions. In addition, they can also plot data points.

The fox population chases the rabbit population. Groups model the populations of foxes and rabbits with two trigonometric functions. Individuals graph both trigonometric models on the same graph, and then teams determine an explanation...

What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

Movie preferences will get your classes talking! Individuals read a pie graph and construct a bar graph using the same information. They then answer questions specific to the data and sample size.

Starbucks or house blend? Pupils analyze the unit rate as the cost per pound of coffee. They use a graph to visualize the unit rate given the cost for a quantity other than one pound.

Spread the word about seafloor spreading! Junior geologists prove Albert Wegener right in an activity that combines data analysis and deep ocean exploration. Learners analyze and graph fossil sample data taken from sites along the...

Not all data is the same. Using the interactive, pupils compare data represented in two different ways. The learners develop an understanding of the difference between discrete and continuous data and the different ways to represent each...

Get close to your favorite line. Scholars use end behavior to help find horizontal asymptotes. With the understanding of domains of rational functions, learners find vertical asymptotes and then use graphing calculators to verify the...

Explore the link between solar energy and cloud cover using real data from NASA from China! Future climatologists analyze and interpret graphs of solar energy on clear and cloudy days using a literacy cube. Investigators draw conclusions...

Is it safe to take data at its face value? Pupils use the interactive to evaluate a claim that Virgos are more likely to get into a car crash than others. Individuals determine whether another variable may be at play.

Put it in your own words. Scholars complete a mini instructional activity about paraphrasing then complete a note catcher using the text A Limited Supply. They continue studying Canada's natural resources by analyzing the graph...

An eye-catching hook makes a smart analogy between ingredients for a food recipe and ingredients for quality relationships. Scholars discuss and list qualities they feel contribute to positive interactions. Pupils create a recipe card...

Color the town red. Demonstrate the concept of graph theory with a task that involves determining the least number of colors needed to color a map so that neighboring countries are not represented by the same color. Pupils...

Fifth graders interpret data and create graphs. Given Fruit Loops, they sort and classify according to color. Using spreadsheet technology, 5th graders record their data and create bar and circle graphs. Students analyze data and...

Students examine the use of bar graphs and histograms. For this data representation lesson, students investigate the proper use of bar graphs and histograms to represent data. They learn the proper geometric definitions, experience...

Second graders study graphing using pictographs and bar graphs. They graph pie charts, line graphs, and also change the graph scale up to 1000. They use the pictograph on the left to create the same graph on the right using a bar graph.
