This collection of probability experiments can be completed with the use of one die. The purpose of each experiment is to compare theoretical and experimental probability through data collection. Each activity includes a PDF document with directions and materials and several activities also include a java applet. | Activity, Game Grade Level: 3, 4, 5, 6+ | |

Students can use this Shockwave applet to learn basic probability concepts and to apply fraction and decimal skills. In Level 1 a number of fish are seen in a tank and users express the probability of catching a red fish as a fraction. In Level 2 the required probability is given as a fraction, and users move more fish into the tank to produce this probability. Level 3 is similar to level 2 but involves a wider range of fractions and some decimals. The Key Ideas page provides background in basic probability concepts. A set of student activity printouts (Probability) is available for further practice. | Activity, Game, Interactive Media Grade Level: 4, 5, 6+ | |

This lesson plan provides students with an opportunity to explore and determine what makes a game fair. Students use spinners with a variety of sector sizes in order to predict which outcome is more likely and then explain their reasoning. Students also experiment with each spinner to see if their predictions are accurate. The lesson utilizes java applets for a spinner and an adjustable spinner, and also includes a PDF of exploration questions. | Lesson Plans Grade Level: 3, 4, 5, 6+ | |

This Cyberchase video demonstrates the concept of fair and unfair games in relation to probability. The video can be viewed in its entirety, 23 minutes, or it can be viewed in short clips, between one and three minutes each. | Video Grade Level: 3, 4, 5, 6+ | |

This lesson plan includes five probability experiments that allow students to make predictions and compare theoretical probability to experimental probability. The lesson plan includes a PDF worksheet that students can use to record and reflect on the data that they collect through these activities. There are several extension questions and activities listed to expand on students' understanding of how experimental probability compares to theoretical probability; one of these activities utilizes a java applet for an adjustable spinner which demonstrates how increasing the number of trials will bring the theoretical and experimental probabilities closer together. | Lesson Plans Grade Level: 5, 6+ |
