Shodor Interactivate: Cantor's Comb
Learn about fractions between 0 and 1 by repeatedly deleting portions of a line segment, and also learn about properties of fractal objects.
Shodor Education Foundation
Shodor Interactivate: Derivate
View the graph and the equation of the line tangent to any function at any point on the function.
Shodor Education Foundation
Shodor Interactivate: Vertical Line Test
Learn about the vertical line test for functions by trying to connect points in the plane to build a function. When you have connected all of the points, you will be told if your graph is a valid graph of a function.
Shodor Education Foundation
Shodor Interactivate: Histogram
View histograms for built-in or user-specified data. Experiment with how the size of the class intervals influences the appearance of the histogram.
Shodor Education Foundation
Shodor Interactivate: Incline
This applet allows the user to make observations about the relationship between speed and position and how both of these are affected by initial velocity and the incline on which the biker is traveling.
Shodor Education Foundation
Shodor Interactivate: Fraction Four
Students play a generalized version of connect four, gaining the chance to place a piece after simplifying fractions, converting fractions to decimals and percentages, and answering algebra questions involving fractions. Choose...
Shodor Education Foundation
Shodor Interactivate: Sierpinski's Carpet
Step through the generation of Sierpinski's Carpet, a fractal made from subdividing a square into nine smaller squares and cutting the middle one out. Explore number patterns in sequences and geometric properties of fractals.
Shodor Education Foundation
Shodor Interactivate: Regression
Plot a bivariate data set, determine the line of best fit for their data, and then check the accuracy of your line of best fit.
Shodor Education Foundation
Shodor Interactivate: Function Flyer
This activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers.
Shodor Education Foundation
Shodor Interactivate: Measures
Enter data and view the mean, median, variance, and standard deviation of the data set.
Shodor Education Foundation
Shodor Interactivate: The Chaos Game
Play the Chaos Game by experimenting with probabilities. Learn about an apparently random process with a not-so-random, geometric fractal result.
Shodor Education Foundation
Shodor Interactivate: Skew Distribution
Change the median and standard deviation of an automatically generated normal distribution to create a skewed distribution, allowing you to observe properties like what it means for the mean, median, and mode to be different.
Shodor Education Foundation
Shodor Interactivate: Plop It!
PlopIt allows users to build dot plots of data using the mouse. View how the mean, median, and mode change as entries are added to the plot.
Shodor Education Foundation
Shodor Interactivate: Normal Distribution
Change the standard deviation of an automatically generated normal distribution to create a new histogram. Observe how well the histogram fits the curve, and how areas under the curve correspond to the number of trials.
Shodor Education Foundation
Shodor Interactivate: Scatter Plot
Graph ordered pairs and customize the graph title and axis labels. Points are connected from left to right, rather than being connected in the order they are entered.
Shodor Education Foundation
Shodor Interactivate: Order of Operations Four
Students play a generalized version of connect four, gaining the chance to place a piece on the board by answering order of operations questions (addition/subtraction, multiplication/division, exponents, and parentheses).
Shodor Education Foundation
Shodor Interactivate: Advanced Monty Hall
Choose one of N doors to experimentally determine the odds of winning the grand prize behind one of the doors, as in the TV program "Let's Make a Deal."
Shodor Education Foundation
Shodor Interactivate: Arithmetic Quiz
This activity gives the user randomized questions to answer on arithmetic with whole numbers and integers.
Shodor Education Foundation
Shodor Interactivate: Buffon's Needle
Experiment with a simulation to get an approximation of Pi by dropping a needle on a lined sheet of paper.
Shodor Education Foundation
Shodor Interactivate: Shape Builder
This activity operates in one of two modes: auto draw and create shape mode, allowing you to explore relationships between area and perimeter.
Shodor Education Foundation
Shodor Interactivate: Crazy Choices Game
Compare theoretical and experimental probabilities, using dice, cards, spinners, or coin tosses. Three different probabilities can be compared at once.
Shodor Education Foundation
Shodor Interactivate: Marbles
Learn about sampling with and without replacement by randomly drawing marbles from a bag.
Shodor Education Foundation
Shodor Interactivate: Julia Sets
Enter a complex value for "c" in the form of an ordered pair of real numbers. The applet draws the fractal Julia set for that seed value.
Shodor Education Foundation
Shodor Interactivate: Fractal Dimensions
Determine the fractal dimensions of several line-deformation fractals. Input the scale factor and number of similar copies, and the dimension will be calculated.
