Lesson Plan Title: Adding and Subtracting Radical Expression Subject: Mathematics Grade Level: 11 Overview: On Day 1, the students will use addition and subtraction skills to solve addition and subtraction radical expressions. The students will gain a better knowledge of algebra and will practice skills using integers and radical expressions. On Day 2, the students will go into the lab to create posters/flyers that provide information about roots. This will help the students gain a better knowledge of roots and will help them better understand simplifying roots to be able to add and subtract them. The students will present their posters/flyers on the promethean to the class; each presentation should take about 1 minute. Approximate Duration: 2 - 50 minute class periods Content Standards:
Algebra In problem-solving investigations students demonstrate an understanding of concepts and processes that allow them to analyze, represent, and describe relationships among variable quantities and to apply algebraic methods to real-world situations.
Benchmarks:
A-2-H recognizing the relationship between operations involving real numbers and operations involving algebraic expressions;
Grade-Level Expectations (GLEs):
Algebra Grade 11-12 Factor simple quadratic expressions including general trinomials, perfect squares, difference of two squares, and polynomials with common factors (A-2-H)
Interdisciplinary Connections:
English/Language Arts : Standard 1 Students read, comprehend, and respond to a range of materials, using a variety of strategies for different purposes. English/Language Arts : Standard 7 Students apply reasoning and problem solving skills to reading, writing, speaking, listening, viewing, and visually representing.
Educational Technology Standards:
Apply strategies for identifying and solving routine hardware and software problems that occur during everyday use.
Objectives: The student will solve addition and subtraction radical expressions to a 60% mastery level using addition, subtraction, and multiplication skills. Lesson Materials and Resources: -Calculators -Pencils and Paper -Worksheets Technology Tools and Materials: Hardware: -Computer -Calculators Software: none Background Information: Students should know how to use calculators. Students should know how to add, subtract, multiply, and divide integers. Students should know how to simplify radical expressions. Lesson Procedures: Day 1: Anticipatory Set- 5 min Bellwork activity that is an ACT Prep. Review- 5-10 minutes of review simplifying radical expressions.
Instruction- 20-30 mins (includes checking for understanding and Guided Practice) Instruct students on the rules of adding and subtracting radical expressions. Work out problems and give examples for the students. Use definitions and examples out of the book to teach the students about working with radical expressions. Check for Understanding throughout instruction. Guided Practice - Within the instruction work out problems and question the students on the next step in the equation. Get a student or 2 to come up to the board and workout a problem with my help. This also helps with checking for understanding. Independent Practice - Give the students a worksheet that they will work in class and the teacher will monitor and help out students when help is needed. What isn't done in class will be finished for homework. The worksheet will be due the next day for a homework assignment. Closure - 5 min Work a problem from the worksheet on the board for students to try grasp concept again since they have been working independently. Introduce the students to the multimedia project that will be completed on Day 2. Day 2 : Students will be walked over to the lab and instructed on how to complete and excel at the project. Directions will be displayed on the board and students will be handed rubrics as they walk into class so they know what is expected of them during this project. They will have 20 minutes to research and create these posters/flyers and will present them for the remainder of the class. Each student will be evaluated using the rubric. Assessment Procedures: -Check for understanding throughout the lesson -Assess some students' ability to work the problems through the guided practice and when the students work through the problems on the board. -Asses all students' ability to work problems from worksheet being looked at for a homework grade. -On Day 2, the students will be assessed on their project and will be graded with a rubric. Accommodations/Modifications: - Provide a worksheet for students to take home, work on, and review skills. -Use Promethean board for students to see problems being worked better. -Use microphone and speaker for students that have problems with hearing. ----- written by Taylor Harlow Explorations and Extensions:
-Students will work on worksheet in class and will take it home for homework. Lesson Development Resources: - Infinite Algebra 2 Reflections: I can determine how fast to move onto the next lesson tomorrow and how thorough the review needs to be before the next lesson is introduced. What activities need to be incorporated. What students need different accommodations. Contact Information: Taylor Harlow
