How tall is the Empire State Building? Lead your class through a collaborative estimation activity to determine the number of quarters it would take to reach the top and teach the following concepts: human capital, human resources,...

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Perform the operation ... and then do it again. Scholars investigate recursive formulas by creating and graphing them. Using the interactive, pupils set the variable, determine the initial value, and type in a recursive formula.The...

Read the story, The Very Hungry Caterpillar, and complete activities from multiple subjects. Make a mural, create a class graph, discuss the life cycle of a butterfly, research information about butterflies on the Internet and make...

How good is the fit? Using an interactive, classmates create a scatter plot of bivariate data and fit their own lines of best fit. The applet allows pupils to display the regression line along with the correlation coefficient. As a final...

What is the relationship between two variables? Groups work together to gather data on arm spans and height. Using the interactive, learners plot the bivariate data, labeling the axes and the graph. The resource allows scholars to create...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

Convert a table to probabilities. Pupils set up the winning rules for the sums of two dice. Using the rules, the applet fills out a table showing the winners for each combination. Learners determine the probabilities of winning for each...

Is GIS the real manifestation of Harry Potter's Marauders Map? Introduce your class to the history of geographic information systems (GIS), the technology that allows for easy use of spatial information, with a resource that teaches...

Scholars decide which job to take based on the pay. They then research cars to potentially purchase and determine the total cost of the car. Finally, they calculate how long they would have to work to purchase the car along with how much...

Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

In this Fact Finder worksheet, students access the Internet to a specific site to find the answers to five questions with multiple choice answers.

In this Fact Monster search engine worksheet, students access the Internet to a specific website to find the answers to five questions with multiple choice answers.

In this Fact Monster search engine worksheet, students access the Internet to a specific website to find the answers to five questions with multiple choice answers.

Make history come to life by using the Frontier House series to engage students in the past. Your class will "prepare" for a trip to 1833 Montana. They will learn about homesteading, frontier life, inflation, and cost of living. Using...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...

Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Students find out how to use annual reports to analyze a corporation whose stock they may buy for the Global Stock Game. They read the investor information section, which provides detailed information about the company's products and...

What does it mean to be financially responsible? Pupils begin to develop the building blocks of strong financial decision making by reviewing how their past purchases are examples of cost comparing, cost-benefit analysis, and budgeting.

Students demonstrate how to tell time using an analog clock. In this time measurement lesson, students read the book Clocks and More Clocks and use analog clocks to demonstrate the time that the teacher called out.

Grab some marbles from a bag. The applet simulates drawing marbles from a bag. Pupils determine the number of four colors of marbles in a bag and how many marbles to draw. Using information on whether order matters in the draw and if...

Fly through graphing functions with the Function Flyer. Young mathematicians use an interactive to graph different types of functions. A set of exploration questions has users investigate patterns in functions.

Derive tangent lines through derivatives. Scholars use an app to graph functions and investigate derivatives and tangent lines. The interactive automatically graphs a tangent line at a specified point and can also produce tables of values.

What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.
