Math Week 3-14-16

7th: Students understand the vocabulary of probability-theoretical vs. experimental. Students understand that probability is expressed between 0 and 1 as a fraction or percent. Students find the probability of simple events. Students understand and can determine probability of both theoretical and experimental probability is expressed between 0 and 1 as a fraction or percent.

CCSS: 7.SP. Investigate chance processes and develop, use, and evaluate
probability models. 5. Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.
7. Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy. a. Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events. For example, if a student is selected at random from a class, find the probability that Jane will be selected and the probability that a girl will be selected.

8th: Students know and use the Pythagorean Theorem to find missing side lengths

CCSS: 8.G.Understand and apply the Pythagorean Theorem. 6. Explain a proof of the Pythagorean Theorem and its converse. 7. Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.
