## Algebraic Lesson

It is important for all students, especially students with disabilities, to be exposed to content-based lessons that promote critical thinking and problem-solving. There are many areas that a student may struggle in when it comes to mastering complex mathematical tasks. For this reason, it is imperative that teachers are equipped with various instructional strategies for handling these situations. Part 1: Operation and Algebraic Thinking Lesson Plan Using the COE Lesson Plan Template, design a lesson for the 1-5 grade level of your choice and a corresponding Arizona or other state math standard within the Operation and Algebraic Thinking domain. Locate four lesson plans that focus on your chosen grade level and math standard from four different websites to review. Using the lesson plans as resources, design a new operation, and algebraic thinking lesson plan that encourages critical thinking. The lesson plan must include differentiated strategies for students who struggle with perception and attention as well as differentiation strategies for students who struggle with memory and retrieval. Part 2: Instructional Strategies Rationale In 250-500 words, reflect upon your instructional choices and rationalize the appropriateness of each strategy related to the specified student needs and learning target. Describe how each strategy encourages critical thinking specific to your lesson. Support your choices with this topic’s readings and a minimum of two scholarly resources. In addition, cite the websites you used as references to develop your lesson plan. While APA format is not required for the body of this assignment, solid academic writing is expected, and in-text citations and references should be presented using APA documentation guidelines, which can be found in the APA Style Guide, located in the Student Success Center.

## Occupational Employment Statistics

The Occupational Employment Statistics (OES) program under Bureau of Labor Statistics produces employment and wage estimates annually for nearly 800 occupations. Browse through the website and pick an industry of your interest and answer the following two questions in your main post: 1) What is the trend of the employment in this particular industry in a particular state/metropolitan area/local county in the last 5-10 years? 2) How has the industry been affected by public health crisis such as the covid-19 pandemic or natural disasters such as hurricane or tropical storms? Support your opinions with statistical evidence or relevant economic articles. In the end, don’t forget to raise a meaningful question to keep the discussion moving. You are strongly encouraged to do research on your topic with at least one reference citation (web citation acceptable) in APA style. Please provide your citation/reference at the end of each post.

## Population Proportion

During the recent election season, you saw many instances where polls were taken and reported, along with the confidence level of the estimate. For example, a poll showed that one candidate had a “”voting for” level of 37%+/-4. The opposing candidate had a score of 39%+/-4 at a 95% confidence level. Because the poll is not a census sample, a sample may be “good” but will have variation around the TRUE population proportion or mean. Thus, the poll is an estimate. The +/- value establishes a range within which the true population proportion is said to be, give a certain level of confidence. However, the reporter said that the second candidate had “a slight lead”. Is this a true statement? Why could it be argued that the scores are “statistically the same”?

## Dexter Masters

All of us are used to multiple-choice tests. If all the exam questions have a choice of 4 different responses (a,b,c,d) what is the probability of randomly guessing the right answer? See! You are all naturally mathematicians! How does this relate to the formulas regarding probability? For example, if the probability of a correct answer was .25, what would the mean (aka expected value) of the distribution be if the sample size was 100? Hint: mean=np For more information on Dexter Masters read this: https://en.wikipedia.org/wiki/Dexter_Masters

## Empirical Probability

Discussion Forum 2Previous Next Prompt Design an experiment to determine the empirical probability that a person will randomly select a can of Coke when given a cooler with equal numbers of cans of both Coke and Pepsi. (NOTE: each person considerately replaces the can after they have selected it, so the total number of cans will stay the same throughout the experiment.)Calculate the empirical probability after five persons. Calculate the empirical probability after ten persons. What is the theoretical probability that a person selected at random would select the Coke? Analyze: How does the empirical probability in your experiment compare to the theoretical probability of selecting the Coke? Why are the probabilities not the same? Post your calculations and respond with your analysis. Read two other posts and comment. For more information on Empirical Probability read this: https://en.wikipedia.org/wiki/Empirical_probability
