8 th Grade CSOPE Performance Indicators7 th Grade CSOPE Performance Indicators Unit 8 third Nine Weeks Create a presentation (e.g., brochure, poster, etc.) with the experimental and theoretical probabilities of dependent and independent events within a given real-life situation (e.g., baseball, snakes, sandwiches, etc.). Make conjectures from the probabilities of the real- life situation, and validate conclusions using mathematical properties and relationships. Design and simulate an in-class experiment with math manipulatives to compare the theoretical and experimental probabilities of a dependent real-life situation. (8.2B; 8.11A, 8.11B, 8.11C; 8.14A, 8.14C, 8.14D; 8.15A; 8.16A, 8.16B) Sample Performance Indicator: There are over 3,000 species of snakes in the world, and only 15% are considered dangerous to humans. Texas has 15 of the 25 species of poisonous snakes identified in North America. With each bite, one-half are “dry”, which means that the snake does not inject venom into the victim. Create an informational brochure to inform tourists about the venomous snakes that inhabit Texas. Include the probability of not receiving a “dry” bite from each type and category of snake, and predict which habitat is most likely to yield the least and most snake bites. Validate the predictions with mathematical properties and relationships. The rattlesnake is one of the most notorious snakes in the Lone Star State; identify the probability of being bit by a snake in a wooded area and it being a rattlesnake. Design and simulate an in-class experiment with math manipulatives to determine the experimental probability of being bit by a venomous snake in a wooded area and it being a rattlesnake. In writing, compare the experimental and theoretical probabilities of being bitten by a snake in a wooded area and it being a rattlesnake. Unit 7 Third Nine Weeks Create a written description (e.g., letter, , etc.) that describes all possible outcomes offered of a given real-life situation that involves simple or composite events. Find the probability, as a percent or decimal, of an independent event within the problem situation. Validate conjectures by constructing the sample space of the given real-life problem situation and identify the problem-solving strategy used. (7.1B; 7.10A, 7.10B; 7.13A, 7.13C, 7.13D; 7.14A; 7.15A, 7.15B) 5F, 5G Sample Performance Indicator: A local copy store offers several choices for customers to select from for their copy needs A supply order was delivered, however pink and blue cardstock were left off the shipment. Write an to the supply company identifying the percent of the orders placed that could involve pink or blue cardstock, and how this error could affect the business of the copy store. Validate the solution by constructing the sample space of the choices offered by Aesop’s Copy Shop and identify the problem-solving strategy used.
