Class Homework No "Class Homework" exist(s) Class Links fraction comparision  experimental probabilityStudents can choose one of six available spinners, figure the theoretical probability of the needle landing on each color of the spinner, then spin it hundreds of times in a second to compare the experimental probability. Or they can work with two regular 6-sided number cubes or even design their own number cubes, and again experiment with the "what should happen" and the "what actually happened." FRACTION OPERATIONSGIVES VISUAL REPRESENTATIONS FOR IDENTIFYING, COMPARING, ADDING, SUBTRACTING, MULTIPLYING, DIVIDING FRACTIONS generic applet geogebracordinate grid for ploting points, lines, circles, functions, and be able to see the angle measure between two line segments probability: simulated drawing An extremely versatile applet! In a box are shown the numbers 1-15, each a different color. Users can select which of these numbers, and how many of each, to add to the pot. As many random draws as 10000 can be made from the pot in just a few seconds. A chart shows the results of the simulated drawing with replacement from the numbers in the pot, as well as the theoretical probability of the drawing. This applet can be used to simulate flipping a coin or tossing a die or picking colored marbles from a hat. probability:adjustable spinnerAnother experiment with theoretical and experimental probability! Students create an interactive spinner with one to twelve sectors; the area of each segment is shown as a percentage in a table. As students spin, they see how many times the needle actually landed on each segment, also shown as a percentage, and compare the two probabilities. |
