Similes and metaphors make writing more beautiful and detailed, but can be a little harder to decipher during a first reading. Use a passage from The Man Who Loved Words to show young readers how to think through passages that...

Triangles, triangles, and more triangles! In this second installment of a 36-part series, your young mathematicians explore two increasingly challenging constructions, requiring them to develop a way to construct three triangles that...

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...

Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...

Find the box with two green balls. The applet uses six balls, three green and three red, and hides them in three boxes. Pupils choose a box and click on it to reveal the color of balls inside. Using the chosen box, the simulation keeps...

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.

Community service is a win-win! Scholars discover how to gain valuable career skills through helping others using a lesson about volunteer work. Second in a six-part career and college readiness series, the activities focus on...

The current population distribution throughout the world is largely based on geopolitical events that have forced groups of people to leave their homes forever. High schoolers learn more about the diasporas scattered around the world as...

The ABC book format is used to organize information found in a Holocaust research project. Class members use the library and/or online resources to collect information and organize their findings under key terms, places, or names. Before...

The wonderful world of Oobleck is entered in order to awaken your learner's sense of touch! As a warm up, learners put their hands in mystery bags in order to identify things that are wet, dry, hot, cold, hard, soft, rough, and smooth....

Students examine how European-America aestheticians (philosophers of art) do not all agree about the value and definition of art. students examine how some cultures do not have a distinct word or definition for art.

“What do you mean that my language is improper?” Prior to My Fair Lady was Pygmalion. Fair Eliza’s struggles with English, which according to George Bernard Shaw “is not accessible even to Englishmen,” come alive in the 1938 film version...

Students experiment with unconventional units (toothpicks, etc.) to estimate and measure. They consider the advantages of using standard measuring units.

Young scientists discuss the results of carelessness during experimentation and the temptation to misrepresent findings. These activities are intended to develop the ability to identify scientific error, misconduct, and fraud. Use this...

State reports can be a lot of fun, especially when the learners get to choose the state they study. This research and writing-focused social studies lesson engages learners in collecting information, essay structure, research, and...

Learners examine and discuss prime numbers, composite numbers, and prime factorization. They develop and create a factor tree mobile using exponents.

Students work in a cooperative groups to create a free standing tower of straws and pins in ten minutes. They watch a video of the cooperative groups working, discuss the process and list the things they could do to improve the cooperation.
