Algebra 2 Std 7: Solve equations, inequalities, and applied problems involving absolute values, radicals, and quadratics over the complex numbers, as well as [simple trigonometric], exponential, and logarithmic equations. Example: solving x²- 4 >0, 3^x =81, 2sin²x + sin x =0, x²- 8x >-12, log_x 2 = 5 Solving equations using laws of exponents, including rational and irrational exponents Expressing the solution of an equation, inequality, or applied problem as a graph on a number line or by using set or interval notation *for Algebra 2 with Trigonometry

Lesson Plans Solving Radical Equations This is an online lesson that offers a good coverage of solving radical equations using analytical methods and graphing. The Absolute Truth Students will communicate their understanding of the methods available to find and check solutions to absolute value inequalities. Exploring Exponential Growth and Decay Functions In this unit, students will use and apply exponential functions of growth and decay in real-world situations. Students will collect and analyze data with the use of the TI-83 graphing calculator, graphs, tables, and other sources. Rhinos and M&M’s® (Exponential Models) The objectives of this lesson are for students to explore the patterns of exponential models in tables, graphs, and symbolic forms and to apply what they have learned to make predictions in a real situation. World Population Study This lesson plan relates exponential growth to population growth. Can Cruddy Cool As Fast As Clean? Students will investigate variations in cooling times for ordinary tap water and salt water. Data will be collected using the CBL unit and the TI-82 calculator to create and interpret data plots. Students will become familiar with Newton’s Law of Cooling and be able to verbalize and write conclusions made from the collected data. Chicago Public Schools Introduction to solving logarithmic equations is given at day 100. The skill occurs several times throughout the chapter. Compound Your Way to a Million Bucks! Many people save and/or invest for their financial security. Students are often not aware of the strategy behind investing. This exercise will examine the question: “Is there a good, better, and best way to invest in an IRA?” The investment patterns of four people will be evaluated to determine if there is a ‘best’ way. Chicago Public Schools This is a collection of structured daily lesson plans on trigonometry complete with activities and assessments (Day 150-151).*
