• Algebra I, Part II (2nd Period)

    The 8th grade Algebra 1, Part 2 course is the second year of a two-year study of Algebra 1. Students are continuing to develop abstract mathematical thinking. Concepts are presented with adequate time to reinforce skills. Upon successful completion of Algebra 1, Part 2, students are prepared for Geometry in high school.

  • Unit 6: Quadratic Equation Word Problems & Radical Functions

    Posted by Alexa Schmidt on 2/4/2019

    Currently in A1P2, students are learning applications of the different methods of solving quadratic equations that they have worked on for the past two units. We are talking about projectile motion, area problems, and maximization problems. We then move on to the inverse of quadratic functions, square root functions.

    To extend at home, ask your child to explain three types of quadratic equation word problems and some strategies for solving each.

  • Unit 5: Solving Quadratic Equations without Factoring

    Posted by Alexa Schmidt on 12/20/2018

    In this unit, covering the end of chapter 8 and selected sections in chapter 9, we are continuing our exploration of quadratic equations. This time, we are solving quadratic equations without factoring them. We learn the following methods:

    • The Square Root Method
    • Completing the Square
    • The Quadratic Formula
    • Graphing

     

    To extend at home, ask your child to explain the different methods of solving a quadratic equation and how to determine which method is the most efficient.

  • Unit 4: Solving Quadratic Equations

    Posted by Alexa Schmidt on 11/26/2018

    This Unit in A1P2, students are learning how to solve quadratic equations by factoring. We will cover multiple methods:

    • Factoring with the GCF
    • Factoring by Pairs/ by Grouping
    • Factoring with the X-Puzzle

    In the next unit, we will learn how to solve quadratic equations without factoring them.

    To extend at home, ask your child how they can check if their factored form is correct. Are there multiple ways to factor the same polynomial?

  • Unit 3: Operations with Polynomials

    Posted by Alexa Schmidt on 10/22/2018

    This unit in A1P2, students are learning the basic operations (+, -, x) with polynomials. This is the preface to our unit on quadratic equations; in order to factor and simply quadratic equations, we must first be able to add, subtract, and multiply together polynomials. We start the unit with a review of properties of exponents and like terms, play games to practice our skills, then end the unit with the more difficult task of finding abstract patterns with special polynomial multipication problems.

    To extend at home, ask your child what it means for two terms to be like terms. What is the relationship between exponents in like terms? When do the exponents change when combining like terms?

  • Unit 2: Exponential Functions

    Posted by Alexa Schmidt on 10/1/2018

    In A1P2, we are extending our knowledge of exponents to graph exponential growth and decay functions, apply exponential equations to interest and population growth, and write recursive formulas for geometric sequences. In class we started the unit off with a "Zombie" lab in which we experienced first-hand how exponential growth starts off small but can quickly get out of hand. We will then move into more practical applications by playing a game of "Who Wants to be a Millionaire" to see who can make investments that will appreciate the most. Finally, we will test our pattern skills with lessons on geometric sequences and recursive functions.

    To extend at home, talk about the interest rates on any checking or savings accounts that you might have. How often is the interest calculated? We did not discuss continuous interest in class, so that might be fun to learn about together!

  • Unit 1: Exponential Expressions

    Posted by Alexa Schmidt on 9/26/2018

    Currently, in A1P2, students are learning how to use the properties of exponents to simplify exponential expressions. We then apply these properties to solve exponential equations and perform operations in scientific notation. We also learn how to write in scientific notation on the graphing calculator.

     

    To extend at home, ask your child if the properties of exponents apply when multiplying and dividing numbers in scientific notation! Why or why not? Can you give an example?
