Sensor technology is amazingly accurate and useful. Combining the sensor technology and mathematical knowledge, scholars design experiments to answer a question they have developed. Questions may focus on light sensing, temperature...

How vulnerable are you to COVID-19? High school mathematicians use the Pandemic Vulnerability Index to create models that help them collect and analyze data about the risk factors associated with COVID-19. After investigating four groups...

The mean might not always be the best representation of the average. The assessment task has individuals determine the measures of center for the salaries of a company. They determine which of the three would be the best representation...

Use graphs to interpret life in 136 counties. Pupils analyze histograms and describe the shapes of the distributions of data collected from several counties on different aspects of life. Scholars make predictions on the difference in...

Biking may be an outlier. Using data from 10 states on the number of people reporting they bike to work, pupils calculate the measures of center. Scholars determine the range and interquartile range and find which provides a better...

What does completing the square have to do with circles? Math pupils use completing the square and other algebraic techniques to rewrite equations of circles in center-radius form. They then analyze equations of the form x^2 + y^2 + Ax +...

Does writing the name of a color in a different colored ink affect one's ability to read it? Scholars design an experiment to answer this question. They collect the data, analyze the statistics, and draw a conclusion based on...

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

Make the most of your prom—with math! Pupils write and use a quadratic model to determine the optimal price of prom tickets. After determining the costs associated with the event, learners use a graph to analyze the break even point(s).

Students define human capital and income earning potential. In this algebra lesson, students analyze the relationship between income and capital resources. They calculate tax rates and understand how to read a tax table.
