What are the chances? Teach your classes to answer this question using mathematics. The first part of a three-day lesson on determining significance differences in experimental data prompts learners to analyze the data by...

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

So trendy! Show your class how to identify trends in sales patterns using mathematics. Scholars use a software simulation to collect data on age groups, price, and sales at a fashion store. This data allows individuals to determine the...

More than half of AP Chemistry test takers earn a high enough score to get college credit. Improve that statistic by using past test questions including precipitate, molarity, and chemical equations to prepare for a future exam. The...

With so many math standards to fit into a school year, it can be difficult keeping track of what you have and have not covered. This collection of Common Core checklists allows you to maintain a running record of when each...

Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Smog? Vog? What is being done about air pollution? Government classes investigate federal and state programs designed to improve air quality, and then develop a proposal for further actions that are needed.

Using a carousel activity, class members gain an understanding of the idea of inferences by using pictures then connecting them to mathematics. Groups discuss their individual problems prior to sharing them with the entire class....

Class members create a table of the number of chords that can be drawn given the number of points on a circle. Pupils analyze the data created, find a function to fit to it, and use the function to make further predictions.

Math is all fun and games with this activity! Learners use an activity designed around hula hoops to collect data. They create scatter plots with their data and then analyze the graphs for correlation. 

Is foot length to forearm length a linear association? The class collects data of fellow scholars' foot length and the length of their forearms. They plot the data and find a line of best fit. Using that line, they make predictions of...

Scholars determine how two quantities vary with respect to each other. They complete a fill-in-the-blank activity by stating whether the entities vary directly, inversely, or jointly, create equations that match different variations, and...

Double the fun — calculate two measures of deviation. The lesson plan provides information to lead the class through the process of calculating the mean absolute deviation and the standard deviation of a data set. After learning how to...

Counting is not all it adds up to be — sometimes it involves multiplying. The lesson introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the formulas...

Examine different types of graphs as a means for analyzing data. Math scholars identify the type of graph from a series of data displays and then develop questions to match each one. Then, given a scatter plot of height versus age...

Not all pie graphs are about pies. The class conducts a survey on favorite fast food categories in a lesson plan on data representation. Pupils use the results to create a circle graph.

How many different interpretations of the mean are there? Scholars place numbers on a number line and determine the mean. They interpret the mean as the average value and as the balance point.

Understanding of probability will probably increase with the use of a refined resource. Pupils learn to distinguish between dependent and independent events as they calculate the probabilities of these types of events in various...

How much time does it take to jump over three balloons? Pupils calculate the speed of tasks that require different motions. They determine motions for tasks such as walking, skipping, hopping, and jumping before creating a...

Help plan a road trip with linear equations. Scholars consider two different rental car companies and write equations representing the cost for each company. They graph the system of equations to determine the conditions under which each...

Which function models the data best? Pupils work through several activities to model data with a variety of functions. Individuals begin by reviewing the shapes of the functions and finding functions that will fit plotted data points. By...

The teacher demonstrates how to use a graphing calculator to create box-and-whisker plots and identify critical points. Small groups then create their own plots and analyze them and finish by comparing different sets of data using box...

Pupils work through a guided activity on fitting a linear equation to a set of data by entering the data into a calculator and trying to envision a line of best fit. They then have the calculator determine the least-squares line and...

Just how far away from the mean is the data point? Pupils calculate the standard deviation for a set of data and find out how many standard deviations a point is away from the mean. The teacher leads a discussion on how to calculate...
