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.
