New! Sample Spaces and Tree Diagrams - Grade 7
6th - 8th
Probability pros conduct a variety of experiments and solve them using tree diagrams and sample spaces to make predictions. They define key vocabulary terms, and observe how to diagram the theoretical probability of tossing a coin three times. To conclude, they design their own probability experiment. The lesson plan is thoroughly written so that you can implement it easily. Let the games begin!
An engaging task awaits your starting statisticians: design a menu for a new cafe that offers a total of 240 combinations of a main dish, a side, a dessert, and a beverage. Creative juices will flow as collaborative groups employ lists, tables, or diagrams to come up with the possibilities. This is a delicious challenge for your math class when learning how to work with sample spaces and compound events.
Sample Space Diagrams and Probability - Independent Events
Six tasks make probability models come to life with this activity. Sample space diagrams and tree diagrams help statisticians compute probabilities of drawing red, blue, or white beads from a bag. Bold font makes this easy to read, and the problems that students work through are practical.
Sandwich this lesson between an introduction to using probability models and analyzing compound events. Your class considers a deli discount in which a customer receives a price reduction based on the roll of dice. Will it be a profitable promotion if the deli owner gambles away profits for the sake of drawing in more customers? Learners observe frequencies to develop a probability model to answer this question. A worksheet, detailed facilitator's notes, and assessment are all included, making this a great deal!
Keys To Trees: Dichotomous Tree Identification
Ninth graders gather samples of different tree leaves in their neighborhoods, and on school grounds, and identify several species of common South Carolina trees using leaf and growth characteristics with aid of dichotomous key.
Finding the Probability of Combined Events
Eighth graders investigate the probability of combined events. In this eight grade probability lesson, 8th graders use a sample space, two events, and their intersections to determine the probability of each event, their intersection, and their union.
Sample Space and Probability Distribution
Young scholars use the sample space to make predictions and analyze data. In this statistics lesson, students apply properties of the probability of an event occurring to solve problems.
Investigation - What's in the Bag?
If you have or can create a set of tiles, numbered one through eight, then you can implement this hands-on lesson about probability models. Individuals draw a tile from a bag, record its number, and then return it to the bag. They predict the probability of the product of three draws equalling an odd number. Teach them how to use sample spaces and tree diagrams to do so. The notes for the lesson are fairly simple, but include two assessment questions and an extension suggestion.
How Do You Use a Tree Diagram to Count the Number of Outcomes in a Sample Space?
Deciding what to wear can be difficult, but it helps if you know your options. Use a tree diagram to solve word problems like the one in this video! Class members can watch and learn how to find and count possible outcomes (or outfits). Play this video as a complement to your lesson or ask pupils to view it at home.
Probability- Many Stage Experiments
Students list the sample space of an experiment. In this statistics instructional activity, students calculate the number of favorable outcome in a given sample space. They define and apply mutually exclusive events versus not mutually exclusive events.
Students explore the concept of probability. In this probability activity, students create a video, poster, or podcast explaining what experiments, sample space, events, and outcomes are in relation to probability. Students create a brochure or PowerPoint explaining the counting rules. Students make a video, photostory, or use moviemaker to show teaching a probability activity or how to find the probability of an event.
