In this investment problem worksheet, students read story problems and use the interest formula to determine the total amount invested, or rate of return. This one-page worksheet contains six problems, with answers.

Rates and ratios can easily be applied to real-world situations. Learners explore a series of websites in order to procure comparable data. They define ratios and rates, view videos, and use the internet to explore how ratios and rates...

What are some of the benefits of physical activity? Young learners take a look at not just the physical benefits, but also the emotional and social benefits of being physically active. There is a heart rate activity to count their...

Young scholars study the Manduca bug and its growth data. They look for patterns and compare their own growth rate to that of the Manduca.

Students investigate reaction rates.  In this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...

View a PBS video entitled Horatio's Drive and explore Horatio's Ratios. Collaborative learners form groups to use Mapquest to determine distances covered. They generate the mathematical averages, ratios, and rates in order to calculate...

For this kinetics worksheet, students review activation energy, rate of reaction, and reaction mechanisms. This worksheet has 13 multiple choice questions.

Young scholars play a game based on "The Amazing Race" to practice using rates and fractions. In this fractions and rates lesson, students work in small groups competing to complete the tasks in the quickest time. At each stage of the...

Explore the concept of work with your class, using bottles, water, and corks to calculate work, while using the formula work = rate x time. Learners conduct multiple experiments, timing how long it takes for water to drain out of the...

It's shark week! In this problem, young mathematically minded marine biologists need to study the fish population by analyzing data over time. The emphasis is on understanding the average rate of change of the population and drawing...

Scholars learn all about the International Monetary Fund. They discover how to calculate exchange rates using an online calculator before completing a short answer assessment. 

In this Using Supply and Demand instructional activity, students draw curves and diagrams, make predictions about graphs, solve problems, and answer questions.

Which is faster, a Ford or a Ferrari? The short assessment has pupils analyze graphs to determine the rates of change between the two. Individuals interpret the rates of change within the context of speeds of the cars and develop a map...

Usain Bolt and Superman have something in common—speed! A video of one of Bolt's races introduces young scholars to the concept of unit rate. Using data from the race, the narrator calculates a unit rate in kilometers per hour, which...

Add up area to find total change. Pupils learn what it means to find the area under a curve and how to calculate it geometrically. They first find the accumulation of change given a rate of change function. Scholars then apply that...

Does a linear or exponential model fit the data better? Guide your class through an exploration to answer this question. Pupils create an exponential and linear model for a data set and draw conclusions, based on predictions and the...

A set of quizzes and assessments would make a great companion to your lesson on making decisions and opportunity risks. Learners watch a PowerPoint before answering multiple choice questions about interest rates, saving money, and the...

Does the home team have the home field advantage in football? Class members look at a graph that displays wins at home and wins on the road for each NFL team from 2002–2012. Then they answer eight word problems that look at the...
