Math

Welcome to our new 7th Grade Math Class!!!

I hope everyone is doing well and staying safe. I miss you all and can't wait to get back to normal classes. I know you all may be anxious to get some new math lessons. On this page I will do my best to continue where we left off.

Directions: Click the PLAY button. Watch the YouTube videos, take notes in your math notebook as you follow along, you can pause and play to keep up, and try some of the practice problems from your textbook. Remember there are answers in the back of your textbook; try a problem and check your answer. If you need help contact me: (928) 890-7597

I'm currently updating; Chapters 9 and 10 will fully be up soon...

10.1: Outcomes and Events

7.SP.5: Understand that the probability of a chance event is a number between 0 and 1 that express 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.

10.2: Probability

7.SP.5: Understand that the probability of a chance event is a number between 0 and 1 that express 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.SP.7: Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies: of 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.

10.3: Experimental and Theoretical Probability

7.SP.5: Understand that the probability of a chance event is a number between 0 and 1 that express 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.SP.6: Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. 7.SP.7: Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies: of 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.b) Develop a probability model by observing frequencies in data generated fro a chance process.

10.4: Compound Events

7.SP.8: Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation. a) Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.b) Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language, identify the outcomes in the sample space which compose the event.

10.5: Independent and Dependent Events

7.SP.8: Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation. a) Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs.b) Represent sample spaces for compound events using methods such as organized lists, tables and tree diagrams. For an event described in everyday language, identify the outcomes in the sample space which compose the event.c) Design and use a simulation to generate frequencies for compound events.

10.6: Samples and Populations

7.SP.1: Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.7.SP.2: Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples of the same size to gauge the variation in estimates or predictions.

10.7 Comparing Populations

7.SP.3: Informally assess the degree of visual overlap of two numerical data distributions with similar variability, measuring the difference between the centers by expressing it as a multiple of a measure of variability.7.SP.4: Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.
