Ciske - Tracz - Nash Math update   04/06/2017
Algebra - We hope you had a great spring break!  Our study of quadratic equations has continued into Chapter 9.  We have learned how to solve quadratic equations by graphing, square roots, factoring, completing the square, and the quadratic formula.  Students should take time to decide which method is best for each problem.  The Chapter 9 Test will be on Monday 4/10.  Chapter 10 will take us into radical expressions and equations.

8CC - We hope you had a great spring break!  Topic 13 will take us into surface area and volume of cylinders, cones, and spheres.  Before we enter into those difficult skills, we thought it would be a good idea to review surface area and volume of rectangular prisms with a Cereal Box Project.  These projects have been mostly completed in class.  We will also take some time to review circumference and area of a circle.  Due to the time constraints of PARCC, the Topic 13 Test is anticipated to occur at the end of April or beginning of May.

Alg - Our new chapter is entitled "Polynomials and Factoring".  We will learn how to add, subtract, and multiply polynomials.  This chapter is rich with new vocabulary.  We will take a quiz on those skills on Tuesday 2/14.  Next we will learn how to factor trinomials.  This is one of the hardest lessons of the year, but it does not take long for students to master it.  The chapter 8 test will most likely occur sometime during the week of 2/27.

8CC - We have begun our geometry unit which spans several topics.  Topic 9 covers congruence and students are learning about translations, refections, and rotations.  Our test on topic 9 will be on Monday 2/13 for Blocks 3 and 4, and on Tuesday 2/14 for Block 5.  The next topic will explore similarity.  In this chapter we will add dilations to our list of transformations.  Our test on topic 10 will occur on Wednesday 2/22 for Block 4 and Thursday 2/23 for Blocks 3 and 5.

Alg - We are kicking off the new year with a unit on exponents and exponential functions.  We will review many properties of exponents but expand our knowledge to include fractional exponents.  There will be a quiz on 7.1-7.4 on Friday, January 20th.  We will then cover rational exponents, radicals, exponential functions, exponential growth and decay, and geometric sequences.  The test on chapter 7 will be on Tuesday, January 31st.

8CC - We survived systems!  We are very proud of our students for sticking with us through those difficult algebra skills.  We are kicking off the new year with a unit on functions.  We will learn how to recognize a functions, learn several ways to represent a function, learn how to distinguish linear and non-linear functions, explore increasing and decreasing intervals, and learn how to sketch functions.  The test for topic 7 will be on Wednesday, January 25th for Block 4 and Thursday, January 26th for Blocks 3 and 5.

Alg - Chapter 6 is all about systems of linear equations.  Again, we've done some exploring with desmos.com and our Nspire CAS calculator app.  We have learned how to solve systems by graphing, substitution, and elimination.  There will be a Quiz on 6.1-6.4 on Thursday, December 8th.  Common Core has us solving word problems all the time, but after the quiz we take a day to focus even more on word problems involving systems.  After which, we will learn how to graph linear inequalities (one at a time) and then systems of linear inequalities (two or more).  The Chapter 6 Test will be on Monday, December 19th.  Have a great winter break!

8CC - Before Common Core, students would not see systems of linear equations until a traditional high school algebra course.  So if math seems more difficult during Topic 6, it's because it is more difficult.  We spent a good deal of time exploring what a system is and how a system can have one, none, or infinitely many solutions.  We are now moving on to solving systems by graphing, substitution, and elimination.  The Topic 6 Test will be on Wednesday, December 14th for Blocks 3/4 and Thursday, December 15th for Block 5.  Students should take advantage of extra help during Xblock throughout this unit and not just the days leading up to the test.  Have a great winter break!
