Students make several models of the solar system to learn the positions of the planets in the solar system as well as relative distances and sizes. Creation of these models will help them identify the planets by size, shape, color,...

The more you text, the less you study. Have classes test this hypothesis or another question related to text messages. Using real data, learners use technology to create a scatter plot and calculate a regression line. They create a dot...

What if you were paid to attend class? What kind of payment schedule would you choose? Learn how exponential functions will eventually exceed linear functions by comparing two different payment schedules for attending class.

Can people predict the number of future divorces? Scholars research and analyze data on the number of divorces and teenage pregnancies in Virginia over time. They use the data to create graphs, determine the best-fit equations, and make...

What locations on Earth get the longest number of hours of daylight in the summer? Hint: It's not the equator! Use real-world sunrise and sunset data to develop trigonometric models that can be used to estimate the number of hours of...

Gain a little interest in functions with a real-life task. Young scholars analyze home loan data with a geometric sequence and series. They use the models to make predictions about the total loan payments at certain intervals in a...

As part of an investigation of transformations of exponential functions, class members use Newton's Law of Cooling as an exponential model to determine temperature based on varying aspects. The resource makes comparisons between...

Starting with similar triangles and dilation factors, this unit quickly and thoroughly progresses into the world of right triangle features and trigonometric relationships. Presented in easy-to-attack modules with copious application...

Physics fanatics time five cars as they pass on the highway. They use the times and a 20-yard distance to calculate velocity. They also graph distance vs. time. A page of student pre-lab questions is provided in addition to the activity...

This is an opportunity for young mathematicians to apply reasoning to solve real-world problems with ratios. Even though there are three candidates for class president, students will only consider two at a time, making the first problem...

Do homework grades really determine test scores? Learn whether lines of best fit, correlation coefficients, and residuals can be used to determine test scores when given homework grades. (It would certainly save teachers time in grading...

It's never too early to start saving for retirement. In fact, the earlier one starts, the better! Use this retirement planning activity to teach the importance of a retirement strategy and why to start at a young age. 

Help pupils to determine whether using square roots is the method of choice when solving quadratic equations by presenting a lesson that begins with a dropped object example and asks for a solution. This introduction to solving by...
