 Function and Algebra Concepts Most of the applets in this section are geared toward fifth grade students and higher; however, some can be modified and used as tools to check multiplication table drill work sheets. Activity: Appropriatelesson ideasfor grades: Can be used to: Simple Plot 3 and 5 Introduce students to the Cartesian coordinate system by having them plot ordered pairs of numbers, either as a scatter plot or with the dots connected. This tool may also be used to allow students to correct multiplication drill work sheets. Ordered Simple Plot 3 and 5 Another version of "Simple Plot" which allows the user to plot and connect ordered pairs in the order that they are input. This enables pictures to be drawn by connecting the pairs rather than having the computer connect them from left to right. Graphit 3 and 5 Introduce students to the Cartesian coordinate system by having them plot ordered pairs of numbers and/or functions similarly to a graphing calculator. This tool may also be used to allow students to correct multiplication drill work sheets. Simple Coordinates Game 5 Introduce students to the Cartesian coordinate system by having them calculate and enter the coordinates of a randomly placed house. This particular applet only deals with the first quadrant. General Coordinates Game 5 Introduce students to the Cartesian coordinate system by having them calculate and enter the coordinates of a randomly placed house. This applet is a more complicated version of the Simple Coordinates Game and uses all four quadrants. Simple Maze Game 5 Allow students to have fun while mastering their understanding of how the Cartesian coordinate system works by maneuvering a robot through a mine field. This applet is only utilizes the first quadrant. Maze Game 5 Allow students to have fun while mastering their understanding of how the Cartesian coordinate system works by maneuvering a robot through a mine field. This applet is only utilizes all four quadrants. Slope Slider Upper level 5 Help students manipulate the linear function F(x)=mx+b and explore the relationship between slope and intercept in the Cartesian coordinate system. Function Flyer Upper level 5 This version of Slope Slider allows the student to enter in the function of his or her choice. This will encourage the user to explore the effects on the graph of manipulating the constants and coefficients. This applet can also be used as tool to correct graphing work sheets. Graph Sketcher Upper level 5 This applet allows the student to enter in the function of his or her choice as well as modify the graph scale size. This will encourage the user to explore the effects on the graph of manipulating the constants and coefficients. This applet can also be used as tool to correct graphing work sheets. Number Cruncher 4 and 5 Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule on without at least having two data points. Whole Number Cruncher 4 and 5 Similar to "Number Cruncher" but only generates multiplication and addition functions to avoid outputting any negative numbers.

 Statistics and Probability Concepts Activity: Appropriatelesson ideasfor grades: Can be used to: Histogram 4 and 5 Have students view their own data, ranging from shoe sizes to the cost of candy bars, using a histogram. A histogram is a bar graph that looks at frequency. Pie chart 3, 4 and 5 Have students manipulate a pie chart to represent their data. Also can be used to familiarize students with percents and their relationship to a whole, while practicing their graph reading ability. Stem and Leaf Plotter 3, 4, and 5 Help students organize and graph data they have collected into Stem and leaf plots. This applet can also be used help students practice calculating mean median and mode. Boxplot 1 3, 4, and 5 Represent and organize data students have collected using a box plot. This tool allows students to view their data in individual sets as well as compiling all their data in to one large set. This applet can also be used to introduce students to the terminology used with box plots. This box plot applet does use the median to calculate the interquartile range Boxplot 2 3, 4, and 5 Represent and organize data students have collected using a box plot. This tool allows students to view their data in individual sets as well as compiling all their data in to one large set. This applet can also be used to introduce students to the terminology used with box plots. This box plot applet does not use the median to calculate the interquartile range Bar Graph 3 4 and 5 Enter data to create a bar graph, then manipulate the graph's maximum and minimum values. Bar Graph Sorter 1, 2, and 3 Sort colored shapes into a bar graph. Appropriate for elementary grades. Circle Graph 4 and 5 Enter data categories and the value of each category to create a circle graph. Similar to "Pie Chart" but the user can define the data set. Understanding Experimental Probability 3, 4, and 5 Experiment with experimental probability using a fixed size section spinner, a variable section spinner, 2 regular 6-sided number cubes or design your own number cubes. Racing Game with One Die 3, 4, and 5 4 and 5 Introduce students to probability by having them work in pairs and experiment with the applets parameters allowing them to "see" the effects of each variable on race results. Racing Game with Two Dice 3, 4, and 5 4 and 5 Further students concept of probability and the effects different variables have on the out come of race results. This applet allows the students to be challenged with more complex math concepts than the Racing Game with One Die applet because it adds another die into the game and allows the race to have multiple contestants. Monty Hall Game 4 and 5 Students choose one of three 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." Parameters: Staying or switching between the two remaining doors. Crazy Choices Game 4 and 5 Allow students to explore theoretical and experimental probability in groups of three playing games of chance using dice, cards, spinners or coin tosses. Spinner 3, 4, and 5 Allow students to explore theoretical and experimental probability. Parameters: Number of sectors, number of trials. Adjustable Spinner 3, 4, and 5 Allow students to explore theoretical and experimental probability. Parameters: Sizes of sectors, number of sectors, number of trials. Marbles 4 and 5 Allow students to explore theoretical, experimental, and learn about sampling with and without replacement by modeling drawing marbles from a bag. Parameters: Number and color of marbles in the bag, replacement rule. Dice Table 4 and 5 Allow students to practice their fraction to decimal and decimal to percent conversion skills while experimenting with the outcome distribution for a roll of two dice by playing a dice throwing game. Parameters: Which player wins on which rolls. Plop It! 4 and 5 Allow students to graph their information using a simple bar graph and investigate mean, median, and mode. Parameters: Range for observations Measures 3, 4, and 5 Have students enter data and view the mean, median, variance and standard deviation of the data set. Parameters: Number of observations, range for observations, which statistics to view, identifiers for the data. Fire!! 5 Allow students to experiment with theoretical and experimental probability. Fire can also be used to develope students awareness of different possible outcomes for multiple step problems as students run a simulation of how a fire will spread through a stand of trees. Parameters: Probability that a tree will set fire to each of its four neighbors. Directable Fire!! 5 Allow students to experiment with theoretical and experimental probability. Fire can also be used to develope students awareness of different possible outcomes for multiple step problems as students run a simulation of how a fire will spread through a stand of trees. Parameters: Probability that a tree will set fire to each of its eight neighbors.
