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.

Progress through various aspects of the  "The Beautiful Era" in this presentation. Political, technological, and scientific contexts surround the time of innovation and change in the world landscape. The short length of this slide...

Students participate in a probability-based exercise. They consider the implications of testing positive for a cancer when the test is less than 100% accurate and analyze their results.

Young scholars identify that yeast are a single celled fungi that are a great model organism for studying respiration in the classroom. They also fill the bulb of a disposable pipet (eyedropper) with yeast, then submerge the pipet in a...

Students make and fly a sled kite out of plastic garbage bags, dowel rods, and more. In this kite lesson plan, students plan the kite to have symmetry and make adjustments as they test it.

Second graders observe and describe the similarities and differences in the African Mask exhibit at the Ackland Art Museum. They use describing words to express the feelings of the masks.

Young scholars read and analyze the short story, "The Hell of Mirrors," by Edogawa Rampo. They write diary entries, develop a video, create an illustration, conduct research, and write a short story.

A short piece on Leonardo da Vinci from the Science Learning Network. Placed here because a) there's a decent drawing of an Archimedes' screw, and b) there's a link to an adequate definition thereof.

This set of lesson plans contains background information on the teacher and school featured in the one hour video Workshop 7: Controversial Public Policy Issues.
