Section 28 Goals Goal To find missing lengths in similar figures To use similar figures when measuring indirectly Rubric Level 1 Know the goals Level 2 Fully understand the goals. as part of the development of the “Math 5: Geometry” curriculum for Arizona State University’s Teaching Foundations Project. . AMP 2012-2013: . Saturday #2. What are we doing here?. Too much math never killed anyone.. Objectives. Learn to . write and solve problems using proportions. . Proportions. Proportions are frequently used to solve problems in mathematics.. Proportional reasoning can be applied in many situations, including reading and drawing maps, architecture, and construction. . Ch. 2 Lesson 3. Pg. 123. What will you will learn?. Enlarge Photographs. Make something from a pattern. Identify Similarity. Two figures are . similar. if the second can be obtained from the first by a sequence of transformations and dilations. In this section we will be able to give real life examples of Fractions and Proportions. We will also learn how to solve and evaluate Fractions and Proportions in word problems.. Lesson plan goals. We are constantly using fractions everyday. Most of the time not really even noticing that we are using fractions. Have you ever checked the clock or a watch for the time? Guess what the time is a fraction of a day so any time you use a watch, clock. Remember to Silence Your Cell . Phone and Put It In Your Bag!. Proportional Variance. Two quantities . vary proportionally. iff as their corresponding values increase or decrease, the ratios of the two quantities are always equivalent.. Statistics. What you will learn. Be able to state the null and alternative hypotheses for testing the difference between two population proportions.. Know how to examine your data for violations of conditions that would make inference about the difference between the two population proportions unwise or invalid.. Ratios. Comparison of two items/objects. Written one of 3 ways. As a fraction. With : (colon). . using word “to”. When writing a ratio. First thing you talk about is the numerator. Second thing you talk about is the denominator. Lesson 5.2: Proportions. Chapter Five: Ratios and Proportions. Lesson 5.2: Proportions. Chapter Five: Ratios and Proportions. Lesson 5.2: Proportions. Chapter Five: Ratios and Proportions. Lesson 5.2: Proportions. two-proportion inference tests. Chapter 22. Proportions observed in independent random samples . are. independent. Thus, we can add their variances. So…. The standard deviation of the difference between two sample proportions is . Difference Between Proportions. Sometimes we want to see if there is a significant difference between independent groups.. Control group vs. treatment group or placebo group. Men vs. women. Last year vs. this year. Jiannan. Wang (.
