AIM: What strategies can you use to find a missing value in a proportion?
HW: Unit 3 Comparing and Scaling ACE #1931, p.2526 Do Now: The ratio of doctors in the U.S. is about 12 men to 5 women. If about 600,000 American doctors are men, how many are women? Classwork: After discussing the Do Now and the various methods of solving (scale factor and proportion) and the different proportions that can be used to solve, we broke into cooperative learning groups. Each group worked on Problem 1.4 AC p.17. We shared responsed to each question and shared any problems that arose while working on them.

HW: Be thankful! Do Now: How can we reflect on our work so far this year? Classwork: Today was all about reflection through work analysis. Students received graded Unit 2 test, quiz, and graphing task which went into their portfolios. Results were recorded onto the tracking sheet. We discussed any issues regarding specific questions on assessments. We also talked about specific methods and strategies to help improve assessment performance. HAPPY THANKSGIVING! AIM: What are some issues created by scaling up or scaling down a recipe?
HW: Unit 3 textbook ACE #1518 p.2324 Do Now: Compare and contrast the ratios below: 2 cups of concentrate to 3 cup of cold water 2 cups of concentrate to 5 cups of juice Classwork: After today's Do Now, we took a notebook check quiz. Students used their notes to answer questions on specific AIM, Do Nows, and model problems from previous classes. This is an effort to force accountability for taking notes which is an integral part of the learning process. It also gets students in the habit of referencing items from the past which is necessary when preparing for examinations and when completing homework. The orange concentrate situation from yesterday was extended today. We discussed parttopart and parttowhole ratios more closely. This allowed us to work on problems that made comparisons with different juice recipes. Resources: AIM: What strategies do you use to determine which mix is more "orangey?"
HW: Unit 3 textbook ACE #1012 p.22 Do Now: Use the following data to make different comparison statements: In a survey, 75 people prefer chocolate and 25 people prefer vanilla. Classwork: Today we used frozen orange juice concentrate mixed with water to make ratio comparisons. This was an intro to parttopart ratios and parttowhole ratios. We looked at a variety of mixtures with different parts of concentrate to water to identify how "orangey" each will be. A lot of discussions took place from prompted statements such as "These two students made different claims about what part concentrate was in the entire mixture. Who was right?" We used several methods to make the comparisons and find true statements. Resources: AIM: What do different comparisons tell us about their relationships?
HW: ACE #15, p.1920 Classwork: Today marked the beginning of Unit 3 Proportional Relationships. Last unit on similarity set the conceptual foundation which we will build upon with proportionality. We began today's lesson by examining common product comparisons we see on TV and in print media (TMobile vs. Verizon; Crest vs. Colgate; Advil vs. Tylenol; Android vs. Apple). Some advertisements and articles compare products with percents, fractions, and words, all of which are ways to express ratios. We discussed the idea of surveys and how they are important in gathering information for market research. Once the information is gathered, decisions can be made based on that data. Students took the role as marketing executives for a soda company, Bolda Cola. It's biggest competitor is Cola Nola (think Pepsi vs, Coca Cola). They were given some statistics from a survey and needed to decide which to use for an upcoming television advertisement. This lesson sets the stage for proportional thinking in the rest of the unit.

HW: Review unit 1 topics on your own. Review notes, use websites, etc. Classwork: Given the halfday for parent teacher conferences today, we had another day of spiral review on rational numbers. We played MATHO  the math version of traditional Bingo. Students filled in blank boards with integers from 20 to 20. They then took turns randomly selecting problems and solving them on the board. The answers were the entries on the MATHO boards. Studemts who earned 5 values in a row (horizontally, vertically, or diagonally) won a prize. I must say, I was very pleased with the appropriateness and general competitiveness of the classes. Congratulations to the winning individuals. AIM: How can we review concepts from the past?
HW: Review unit 1 topics on your own. Review notes, use websites, etc. Classwork: We concluded Unit 2 on Similarity yesterday. In an effort to keep previous topics fresh in students' brains, we engaged in a spiral review. We played Rational Numbers Jeopardy to make for a more engaging review. Classes were broken into teams of 3 and competed against each other by answering questions together to earn points. Categories included: Adding Rational Numbers, Subtracting Rational Numbers, Multiplying/Dividing Rational Numbers, Order of Operations, Distributive Property. Congratulations to the teams that came out on top! I'd also like to applaud everyone for displaying good sportsmanship and appropriateness during these thrilling games.

HW: No homework Classwork: Unit 2 Exam Resources: AIM: How can we practice our unit 2 skills? HW: Review topics from Unit 2. Actively study vocabulary words, practice problems online, review notes from class. Classwork: We continued our practice on Unit 2 by taking a practice exam. Students worked individually or with a neighbor to answer multiple choice questions and short answer questions. After a period of uninterrupted student work, students engaged in a peer review of problems  meaning they took turns being the teacher explaining selected problems to the class. The practice test we worked on, along with correct answer can we downloaded below.

AIM: How can we practice our unit 2 skills? HW: Review topics from Unit 2. Actively study vocabulary words, practice problems online, review notes from class. Classwork: Today we practiced a variety of questions from Unit 2. Students worked with partners and responded to question sets using the smart response clickers. Feedback was provided at the end of the period to help students identify their strengths and weaknesses in the unit. The question set, along with answers, is located below. Students are responsible for the following topics and more for the unit exam: Similarity  same shape different size; corresponding angles are congruent, corresponding sides are proportional Congruence  same shape, same size; all parts of one figures are exactly the same as another Scale Factor  number which scales, or multiplies, some quantity (percents, fractions, decimals) Proportions  used with corresponding sides to determine similarity or find missing pieces Adjacent Side Ratios  to determine similarity or to find missing pieces Graphing points on a coordinate plane Stretching and shrinking on the coordinate plane Moving figures on the coordinate plane Perimeter and Area with similar figures Shadow Method  find the height of tall objects that are difficult to measure Resources:
