Introduction
Seeing structure in Expressions
In this lesson, students will learn to interpret the structure of expressions. In doing so, teachers need to help students understand what is meant by structure of expressions. Which means breaking down of the expressions to simplify them. Students must first be familiar with Identify the different parts of the expression. Students should be able to explain the meaning of these parts within the context of a problem. Breaking down expressions and making sense of the multiple factors and terms to explain the meaning of the individual parts help students understand the context. Students will also learn to recognize the terminology used to interpret the expressions such as terms, factors, and coefficient. Students will re-work algebraic expressions in different parallel forms by factoring or combining like terms.
Task
Students are the Find out ..
- What are the different parts of an expression? (ie. terms, factors, and coefficients)
- How do you write and solve quadratic expressions?
- What is the quadratic formula and complete the square?
Process
Mathematics is a series of numerical geometric skills, used to teach students mathematic language. Each standards of mathematics is broken down into Parentheses, Equations, Multiplications, Divisions, Addictions, and Subtractions. Students can use technology equipment to enhance their learning skills. The main goal is to teach students the importance of problem solving using technology skills to improve their learning ability. The knowledge and instructions will be applied through the proper learning process.
As a ninth grade math teacher the job duties would be to ensure the mathematics skills are taught with an understanding of problem solving. In order for students to distinguish the difference between numbers and problems. They have to beware of the proper steps to solve math problem the goal is to give examples and practice math on a daily basis. All rules of learning will be applied in this learning experience as well as the resources and material tools to help with assignments. Every student will be assisted throughout the classroom with guidance and understanding of their duties as ninth graders.
Students are to enhance their learning through the use of technology. For example: using a calculator to help solve problems or visualize, using strategies to solve a mathematics problem. The only way to be an effective learner is to research and practice. According to, (Close, 2012), “the other source is the experimental-type study, in which groups of students participate in controlled conditions in which calculators form a special part of the teaching, learning and assessment involved.
Students will have the opportunity to work on assignments completing mathematic problems. Ninth grade math is given to help students start off fresh, during the beginning of high school, with early learning skills in a classroom setting. Every effort and attempt of using techniques to problem solving is accepted and addressed. Students will be instructed to give a demonstration of their ability to stay focused and do their best. All lines of communication will remain open for answers to any questions students may have. Participation is required at all times within the classroom. Math will be done using technology skills and visualization.
Students should use the following links along with research of theirown to complete the worksheets and work given in the classroom for this webquest:

Conclusion
Conclusion
Math is one of the most difficult subjects in the common core curriculum today. Math is everywhere and as students you will use it daily. It may not be a persons faviorte subject or the most popula however through what you will have learned through this lesson and through the worksheets you will learn how to properly define expressions and how to use the quadratic formual and complete square. By learning all of these lessons one shall be able to incorporate it in the rest of their mathematics career and make it a successful one. The tools you learn from this lesson will also enhance your ability to become your own boss and have your own business. It gives you skills to manage everyday life and situations you may face. Make sure at the conclusion of your work that it is all in order and turned in with all work finished there is a rubric for this assignment and it will be followed.
