If all the mined gold in the world was melted across a football field, it would rise 5.4 feet. That's just one interesting fact pupils learn when using the debate topics website to determine if the United States should return to a gold...

Many people think the best solution to the Israeli-Palestinian conflict is a two-state solution. After reviewing the available resources, scholars determine whether they agree with that approach. They analyze graphs and charts about...

Using rates from a rental car company, young mathematicians graph data, explore linear relationships, and discuss the role of slope and the y-intercept. This lesson allows for the discussion of independent and dependent variables, as...

Students explore the changes in sea ice over several years. In this life science lesson, students review and examine 20 years of data. They use Excel to graph data and analyze trends.

Some things are hard to resist. Small collaborative groups build circuits and calculate the voltage using Ohm's Law. Budding engineers explore the connection between the voltage across different resistors and linear...

Life science learners construct lung-o-meters from gallon-sized milk jugs and then measure their lung capacities. For older students, have them graph the vital lung capacities of each person in the class. Cross-curricular pieces are...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

This fourth of twelve units in a series continues the investigation of functions through equations and inequalities. However, the modular nature of the lessons in the section make this an excellent resource for any curriculum...

Be shore to use this drifter resource. The third installment of a five-part series has learners using the NOAA's Adopt-a-Drifter website to track to movement of a drifter (buoy) in the ocean. Graphing the collected data on a map allows...

Planetary atmospheres vary greatly from planet to planet. Explore these variations by experiencing the motion of the atmospheric molecules through an engaging simulation. Pupils discover that temperature and mass contribute to...

Line up the temperature conversions. Pupils create the linear function between Celsius and Fahrenheit on a graph by plotting the freezing and boiling points of water. The scholars determine how the relationship changes based upon...

Pupils determine the probability of one mayoral candidate winning given the other's chance. The interactive provides a circle graph to help visualize each candidate's percentages of winning.

Functions are special types of relations, but what makes them so special? Pupils use an interactive to slide a vertical line across six different graphs. Ten challenge questions then assess understanding of functions.

To be (a function) or not to be (a function). An easy-to-use interactive has pupils drag a vertical line onto several graphs to determine if they represent functions. Some challenge questions assess understanding of this idea.

Cook up a good resource for systems of linear inequalities. Using an interactive, individuals graph a system of linear inequalities to represent constraints on the number of cookies a person must bake. A set of challenge questions...

Ride to success in checking solutions to equations. Scholars use an interactive graph to identify points that are solutions to a linear equation. Interpreting these points in terms of the context completes the activity.

Create a history of car sales. Pupils create a histogram/bar graph to show the number of car sales made during the week. Using the data display, learners calculate numerical summaries of the data and find the percent of cars sold during...

Connect the dots on frequency. Given a distribution table of scores on an assessment, learners create a frequency polygon by moving points on a graph to the correct frequency. The pupils use the display to answer questions about the...

Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...

Cameras use histograms to communicate the exposure of a photograph. An interesting lesson uses this idea to help learners deepen their understanding of histograms. It highlights the skew of the graphs by showing under- and overexposed...

Compound statements are actually quite simple. A virtual interactive provides a means to graph solution sets to compound statements involving and and or. Users then answer a few challenge questions on these solution sets.

There's nothing normal about an extraordinary resource. Scholars change the dimensions of a normal distribution using a slider interactive. Determining the area under the graph gives probabilities for different situations.

Rational functions become less mysterious when you know about limits. Individuals use an interactive to move a rational function on a coordinate plane and to investigate function values for certain x-values. They see how the limit...

There are an infinite number of reasons to use the resource. Scholars drag vertical and horizontal lines to the graph of a rational function to identify all asymptotes. They investigate the connection between asymptotes and limits to...
