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...

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness. 

Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...

Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

You'll have no regrets when you use the perfect lesson to teach regression! An interactive resource has individuals manipulate the slope and y-intercept of a line to match a set of data. Learners practice data sets with both positive and...

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.

Writing an equation of a line is as easy as m and b. A lesson presentation gives individuals different strategies for writing equations of lines. Some items provide a slope and a point while others provide two points. Whatever the given,...

Pupils analyze a display of data and review dot plots to make general observations about the highest, lowest, common, and the center of the data. To finish, learners match dot plots to scenarios. 

Students explore how to multiply and divide by 10, 100, and 1000. In this computation lesson, students participate in an online activity using the interactive whiteboard. Students generate sums by using dice.

Second graders convert fractions to percentages.  In this interactive whiteboard percentages lesson, 2nd graders problem solve using percentages, fractions, and decimals.

Students explore subtraction. In this mathematics lesson, students practice how to subtract numbers from 20, 100 and other whole numbers. Students realize that there are number bonds which can help with subtraction like 3 and 17 bonds to...

Students use a calculator to solve math problems. In this calculator usage instructional activity, students get into pairs and familiarize themselves with the keys. Students are then given problems to solve using the calculator. Students...

To prepare for a field trip to a local art museum, art class members journal their initial reactions to a reproduction of the work they will focus on during their visit. The whole class then considers the artistic elements in the piece...

One of the most common questions in a science classroom is, "Do we get to dissect anything?" With a fun and interactive experience, your eager biologists can perform a virtual dissection on a frog, as well as learn about different kinds...

Which dot am I? Pupils create dot plots to represent sample data through the use of frequency tables. The third segment in a series of 22 asks individuals to analyze the dot plots they created. The scholars translate back and...

Eighth graders conduct research on various careers that are of interest to them. They conduct Internet research on a selected career choice, and create a nine card stack using HyperStudio to describe their career's salary, required...

Young scholars cooperate in small groups to create an audio tour of a zoo exhibit during a field trip. They record personal reactions, zoo sounds and information learned about the exhibit. They then edit the audio recording and add music...

Some things remain the same, such as the world being on the brink of war, or college attendees writing home requesting money. As part of their research into events that led up to President Wilson's declaration of war on...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

The incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson...

Chart your way to an understanding of nanoscale. Using a Google map, learners estimate a radius around their location of 1,000 and 1,000,000 meters. Predicting what 1,000,000,000 meters would look like takes them off the charts!...

Don't let your eyes play tricks on you ... use scale to keep your eyes in check! Young scholars observe images without scale and try to identify the structure. Then, they look at the same image with a scale bar and assess whether their...
