# Give Us Our Daily Math

Middle schoolers may not easily see the connection between data analysis problems invented for the classroom and math problems encountered in their daily lives. You will spark their interest in data analysis by showing them its value in finding solutions to real problems in many settings — from buying a soda to taking after-school jobs to understanding weather reports. When you introduce data analysis to middle school students, you are exposing them to applications that correlate with the NCTM Principles and Standards: creating and reading graphs, calculating statistics, and, above all, solving real-world problems.

Working Hours: How Much Time Do Teens Spend on the Job?
This activity challenges students to interpret a bar graph to determine the average number of hours teenagers work per week. A hint suggests that students assume that 100 students participated in the survey. Interesting statistics about the hourly wages and annual salaries of various occupations are given.

Does It Make a Difference Where You Shop?
In this online activity, your students compare soda prices from two stores using data displayed on a scatterplot graph. Students are shown how the line y = x can be used to analyze the data and draw a conclusion. Further problems involving scatterplots compare car mileage and the performance of NBA players.

The Global Sun Temperature Project
This web site allows students from around the world to work together to determine how average daily temperatures and hours of sunlight change with distance from the equator. Students can participate in the project each spring, April-June. You will find project information, lesson plans, and implementation assistance.

New York Times Daily Lesson Plan: Mathematics
These lesson ideas from the New York Times offer suggestions for ways to draw on real-world issues and statistics to develop lessons in mathematics. Each lesson idea includes a description of the activities along with handouts and questions for discussion. Links to related Times articles provide an interactive aspect to each of the lesson entries.

# Math in Spring and Summer Sports

In the springtime, some middle school students enjoy outdoor sports much more than they enjoy their math classes. Why not use two of these popular sports to our advantage in the classroom? The following problems with baseball and track themes challenge students to exercise some of the skills they learn in the middle school curriculum.

What Is Round, Hard and Sold for \$3 Million?
This activity challenges students to determine which is worth more today: Babe Ruth’s 1927 home-run record-breaking ball or Mark McGwire’s 70th home-run ball that sold in 1999 for \$3 million. Compound interest is the main topic.

Who’s On First Today?
In this activity, students use hits and at-bat statistics to determine which of two baseball players has a better batting average.

Fun with Baseball Stats
In this lesson plan, students use baseball cards to convert statistics to decimals, fractions and percentages. Then, they use their statistics in playing a game. Activity sheets can be downloaded.

Can You Run As Fast As a Car?
This activity asks the student to determine if Florence Griffith-Joyner moved faster than a car traveling 15 miles per hour when she ran 10 meters at a record-breaking 0.91 seconds during the Seoul Olympics. Along with the answer, students will find a description of how to make unit conversions and other problems related to conversions of units of measure for volume, distance, currency, and temperature.

We want and need your ideas, suggestions, and observations. What

students asked? We invite you to share with us and other readers
you think and tell us how we can serve you better. We appreciate
your feedback on all of our Middle School Portal 2

# Using Real Data in Environmental Science Classes

Students are naturally curious about the world they live in. What better way to satisfy this curiosity than by giving them hands-on opportunities to collect data and find answers to their questions? These resources provide opportunities for students to collect data and to present and analyze their findings. These skills are an important part of the Science as Inquiry strand in the National Science Education Standards.

Down the Drain: How Much Water Do You Use?
In this Internet-based collaborative project, students collect data from their classmates and from members of their own households to determine the average amount of water used by one person in a day. They can share that information with other classes online and compare the average amount of water used per person per day in other parts of the country and the world. The project goes beyond merely collecting data to considering some real questions on wasted water.

Global Learning and Observations to Benefit the Environment (GLOBE)
Students participate in this environmental science program by collecting local data, such as air temperature, cloud cover, and soil moisture content, and posting that data on the web site. The growing body of data is available to both scientists and students. Although only GLOBE-trained teachers can have their students post data on the web site, anyone can view or download the data.

Earth Exploration Toolbook: Using GLOBE Data to Study the Earth System
This site guides students through the process of locating and graphing web-based environmental data that has been collected in the GLOBE program. Basic concepts in Earth science are explored as students investigate a specific case study. The GLOBE Graphing Tool is used to superimpose four different environmental data sets as a single graph to show otherwise hidden relationships. Seasonal changes in soil moisture are highlighted, as are the concepts of reservoirs, the flow or flux of moisture between reservoirs, and the role of solar energy as a driver of this flux.

Journey North: A Global Study of Wildlife Migration and Seasonal Change
In this online project, students share their field observations with other students across North America. They track the coming of spring through the migration patterns of monarch butterflies, bald eagles, robins, hummingbirds, whooping cranes, and other birds and mammals; the budding of plants; changing sunlight; and other natural events.
