[Free Registration/Login Required] Connects what we have learned about slope as a ratio to linear equations. We had previously used the term rate of change, but can now connect it to the idea of slope. There are information pages and...

In these KQED Lowdown infographics, explore how adult obesity rates in the United States, as measured by body mass index (BMI), have dramatically changed in the past half-century. A circular graph and a pictograph depict data by decade,...

Students examine differential equations and slope fields in this rate of change example. The resource consists of an enlarged printable version of a slope field available in PDF format.

Explore the inflation rate from 2013 through this informative case study. Trace the consumer trends through the graphs and charts on the site.

This resource consists of graphs and articles that review general demographic changes and related national policies on migration. The goal is to provide information about general population trends, while encouraging a critical...

Investigate data on changes over time in where our apparel is made and how much we spend on it in these images from KQED. In the accompanying classroom activity, students use the interactive and graph the data. They also look for...

Explore the relationship between degrees Fahrenheit and degrees Celsius. This video focuses on developing an expression to model the relationship between the temperature scales using a line graph to calculate slope and the y intercept.

This site gives a concise outlook of the United States Economy in the early twenty-first century. The summary is brief, but it is easy to read and understand. Includes numerous links to graphs.

Interpret graphs showing changes over time in the percentage of foreign-born US residents and in annual deportations in this interactive from KQED. In the accompanying classroom activity, students use the interactive and look at how...

In this activity, students simulate the spread of a virus. They produce a graph representing the spread and analyze the rates of change over time. Students compare how viral and bacterial infections spread in a population.

Using Avida-ED freeware, students control a few factors in an environment populated with digital organisms, and then compare how changing these factors affects population growth. They experiment by altering the environment size (similar...

Dozens of statistical terms are defined and illustrated in this glossary.

In this problem, young scholars are presented with the equations of two linear functions and their intersecting graphs. They are asked to label the graphs and compute values for several points on the graphs. Aligns with F-LE.A.1.b.

[Free Registration/Login may be required to access all resource tools.] Evaluating and solving basic exponential functions, introduction to ''e''.

This lab is designed to have students investigate the factors that affect the rate at which a capacitor charges. Students can change the resistance and capacitance in the circuit and monitor the current, voltage and charge on the...

This site from the World Bank provides data on population for most of the countries of the world in 2020, and shows the change in the rate from 1960 to 2020. Statistics are presented in a chart, line graph, bar graph, and map. The data...

This lab is designed to have students investigate the factors that affect the rate at which a capacitor discharges. Students can change the resistance and capacitance in the circuit and then monitor the discharging of the capacitor....

This lab is designed to have students investigate the factors that affect the rate at which a pendulum oscillates. Students can change the length of the pendulum, the angle of release, and the heavenly body on which the pendulum is...
