Is 0.56 stronger than -0.78? Interpret the correlation coefficient as the strength and direction of a linear relationship between two variables. An algebra lesson introduces the correlation coefficient by estimating and then...

Of course, there might be a correlation! Young mathematicians investigate several different data sets, create scatter plots, and determine any correlation. They consider whether a causation exists between any of the variables in question.

Reinforce number sense with a collection of math lessons for kindergarteners through fifth graders. Young mathematicians take part in hands-on activities, learning games, and complete skills-based worksheets to enhance proficiency...

Statistics come front and center in this unit all about analyzing discrete data. Real-world situations yield data sets that the class then uses to tease out connections and conclusions. Beginning with the basic histogram and...

Investigate the effect of one-axis rotations on geometric figures. Scholars learn to use snap cubes and the right-hand rule to draw figures after rotations about the x-, y-, or z-axes. They try their hands at examples created by the...

Twenty slides make up a set of festive, May-themed writing prompts designed to grab scholars' attention and warm-up their writing skills. Prompts include story starters, holidays, research questions, the five senses, and more! 

Trees are the star of a three-step unit celebrating Arbor Day. Step one takes an in-depth look into the structure of a tree, the process of photosynthesis, and the benefits of the leafy giants. Step two challenges scholars to create a...

During a cholera outbreak, scientists presented two theories; one theory was based on miasma and the other on germs and contaminated water. The lesson looks at the scientific process for finding the real culprit. 

The Renaissance is the theme of a five-week unit designed to boost reading comprehension, spelling, vocabulary, and expository writing skills. Scholars listen to and discuss daily readings and engage in skills practice activities...

Is there a correlation between the number of cats you own and your age? Use a scatter plot to analyze these correlation questions. Learners plot data and look for positive, negative, or no correlation, then create stem-and-leaf plots to...

Is there a better way to display data to analyze it? Pupils represent data in a variety of ways using number lines, coordinate graphs, and tables. They determine that certain displays work with different types of data and use...

Mortgages, payments, and wages correlate with each other. The short assessment presents scatter plots for young mathematicians to interpret. Class members interpret the scatter plots of price versus payment and wage versus payment for...

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

Find a statistical reason for a fresh start. Using a hypothetical scenario, individuals research statistical data of three different cities. Their goal? Find the best statistical reason for a business to move to a new location. Their...

Scatter plots tell a story about the data — you just need to be able to read it! Building from the previous lesson in the series where learners created scatter plots, they now learn how to find associations in those scatter plots....

Class members investigate relationships between two variables in the seventh installment of a 16-part module that teaches scholars how to find and describe patterns in scatter plots. Young mathematicians consider linear/nonlinear...

Build your library of strategies and activities for teaching phonemic awareness with the ideas provided in this resource. Described here are five different activities to try out with your class.

Do you have an energy hog in your home? Individuals pick at least one room at home to determine the amount of energy the appliances consume. Using that information, pupils fill out a worksheet to determine the cost of running each...

Bring awareness to the ingredients scholars ingest daily with two lessons that look deeply into food labels. The first lesson explores the difference between processed and fresh foods while the second lesson focuses on sugar content.

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

The final lesson in the 20-part series is a post assessment covering earthquakes and volcanoes. Twenty-three questions incorporate each of the previous lessons through multiple choice, justified multiple choice, expanded multiple choice,...

Develop a deeper understanding of statistics. The six released free-response items from the 2002 AP® Statistics Form B involve several concepts that are currently in the regular statistics standards. Teachers see how...
