Book: Chapter 10 INTERACTIVE GAMES
10.01 Simplifying Rational Expressions Objective: To simplify rational expressions Narration: A rational expression is in simplest form when the numerator and denominator have no common factors other than 1 or 1. You will need to first factor the numerator and denominator, then look for ones to reduce the rational expression. Algebra Notes - http://www.algebranotes.com/ - Lesson 11-3 Assignment: Page 434: #1 21
10.02 Multiplying and Dividing Rational Expressions Objective: To multiply and divide rational expressions Narration: Rational expressions follow all of the rules for multiplying and dividing fractions. When multiplying, multiply numerators and multiply denominators. When dividing, invert the second rational expression and then multiply. Algebra Notes - http://www.algebranotes.com/ - Lesson11-4 Assignment: Page 437: # 3 13, 25 28, Page 440: #7 17
10.03 Adding and Subtracting Rational Expressions with Like Denominators Objective: To add and subtract rational expressions with like denominators Narration: To add and subtract rational expression with like denominators, add or subtract the numerators, and write the sum or difference over the common denominator. Algebra Notes - http://www.algebranotes.com/ - Lesson 11-5 Assignment: Page 443, #4 14
10.04 Adding and Subtracting Rational Expressions with Unlike Denominators Objective: To add and subtract rational expressions with unlike denominators Narration: To add and subtract rational expression with unlike denominators, you must first convert the expressions so that the denominators are common to both. This follows the same format as adding fraction with unlike denominators. Algebra Notes - http://www.algebranotes.com/ - Lesson 11-5 Assignment: Page 448: #7 12, Page 449: #35 42
10.05 Solving Rational Equations Objective: To solve equations involving rational expressions Narration: To solve a rational equation multiply both sides by the LCM of all the denominators. Assignment: Page 453: #7 17
10.06 Work Problems Objective: To solve problems using rational equations Narration: In general, if a job can be completed in t hours, then 1/t of the job is completed in 1 hour. Algebra Notes - http://www.algebranotes.com/ - Lesson 11-7 Assignment: Page 458: #1 4
10.07 Mixture Problems Objective: To solve problems involving the mixture of substances Narration: The grid format that was used in motion problems will be used here. Algebra Notes - http://www.algebranotes.com/ - Lesson 7-4, 11-7 Assignment: Page 462-63: #1 8
10.08 Complex Rational Expressions Objective: To simplify rational expressions Narration: A complex rational expression has a rational expression in the numerator or denominator or both. Assignment: Page 470-471 : #7 9, 13 18
10.09 Shopping in Tokyo Objective: To apply the concept of rational expressions. Narration: See this link to complete this assignment.
10.10 SET Objective: To develop reasoning skills Narration: The more frequently you play this game, the faster you will develop your mathematical reasoning skills! Assignment: Continue to play the game of SET at least twice per week. Continue to record your time on your Excel spreadsheet and email it to your teacher each week.
10.11 Self Test Objective: For you to complete the self test with a perfect score. Narration: Complete the self test which is a review of the concepts you learned in this lesson before you take the Module Test. http://phschool.com/atschool/california/mathematics/algebra1/Student_Area/ALG1_SC10_ST_index.html Assignment: Email your score to your teacher.
10.12 Module Test Your teacher will let you know how you can complete this test.
