A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

Statistically speaking, the content covers several grades. Featuring all of the statistics typically covered in a college-level Statistics course, the expansive content spans from sixth grade on up to high school. Material...

How do you assure that the resources you find for your classes are of good quality? Check out a vetting rubric that suggests eight questions to ask when considering lesson plans, activities, demonstrations, and pictures for classroom use.

What information can come from a box? Learners choose a data set to display as a box plot and decide whether to include the median in the calculation of the quartiles, show the outliers, and change the scale. To finish the lesson,...

Scholars see cross sections come to life using an app to investigate cross sections of three-dimensional solids. They look at prisms, pyramids, cylinders, cones, and double cones.

Let coordinate pairs show you the way home. Scholars plot houses on a coordinate plane with given coordinates using an interactive app. Alternatively, they can identify the coordinates of houses already plotted on a coordinate plane.

Spin into a dicey experiment. Pupils use a spinner or a pair of dice to determine the experimental probabilities of each outcome. The interactive allows for either, one, five, or ten consecutive experiments. Using the applet, learners...

Green roofs aren't just eco-friendly — they are literally green with trees. Groups learn about the concept of green roofs in order to be able to design one. The groups design a 5,000-square-foot green roof for a fictional apartment row...

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.

Polar opposites might not work together—but polar coordinates do! The interactive provides learners the opportunity to graph trigonometric and algebraic functions using polar coordinates. The program takes either individual data points...

How does life evolve? The interactive provides a simulation based on the Game of Life invented by mathematician John Conway. Users can run the applet with the preset rules and settings or adjust them to view whether overpopulation or...

Connect the points to create a function. Using points given by the applet, pupils try to connect them to create a line that would pass the vertical line test. The resource keeps track of the number of sets the learner is able to identify...

Find the needle on a lined paper. Pupils run a simulation of dropping a needle on a lined paper. The probability of the needle crossing at least one line is pi/2. After each trial, the interactive displays the approximation of pi based...

A change in a parameter can end in overpopulation. The resources gives pupils the opportunity to control the parameters of rabbits and wolves in a natural setting. Using the set parameters, the simulation runs and displays the population...

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...

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,...

Pasta is great for cooking—and for making Ferris wheels. Aspiring engineers use an assortment of pasta types to create a functioning Ferris wheel. They keep track of the design process to refine their designs, if necessary. Let's hope no...

Don't leave learning to chance! Assess your class's understanding of random sampling and making inferences using questions from the experts at Smarter Balanced. As the seventh of nine parts in the Gr. 7 Claim 1 Item Slide Shows...

The plot thickens to get a functional understanding. After a short review of plotting points on the coordinate plane, class members learn the difference between functions and relations in the second lesson in a series of nine. They...

Students consider the factors that relate to decisions regarding genetic disorders. They read case studies and complete a provided Bio-Ethical Decision-Making Worksheet.

Tenth graders identify stars based on their line spectra. In this astronomy lesson, 10th graders analyze spectrograph and determine the elements present in the star. They explain the relationship between temperature and star classes.
