8th Algebra Update 10/13/19

I hope everyone is enjoying the long weekend! Last week, we continued to use our knowledge of solving equations to write and solve equations to represent different situations. We also practiced rearranging equations with multiple variables. We then took our Unit 2 Test on Thursday. This week, we will begin by reviewing the two-dimensional coordinate plane before moving on to review transformations. This will preview transforming functions later in the chapter. We will also explore how to extend our knowledge of solving equations to solve absolute value equations and derive the distance formula.

Unit 2 Test Review Material KEYS

8th Algebra Update 10/6/19

Last week, we focused on using basic moves to solve different types of equations. We also explored instances where linear equations could have one solution, infinitely many solutions, or no solutions. We took a quiz over these topics on Friday. This week, we will extend our knowledge equations by writing equations to model different situations. We will then plan to take our Unit 2 Test.

8th Algebra Update 9/29/19

Last week, we explored how to undo a list of steps. We noticed we have to reverse both the order of the steps and each operation. We used this to backtrack and solve equations by undoing the order of operations. This week, we will explore how to solve equations in a more traditional manner and look into the meaning of the solution to an equation. We will then look to take a quiz over these topics.

Quiz 2.06-208 Study Guide KEY

8th Algebra Update 9/22/19

Last week, we focused on writing, simplifying, and evaluating expressions. We then took a quiz over these topics on Friday. This week, we will explore reversing operations and backtracking to find an initial value. We will then take a small quiz over these topics.

8th Algebra Update 9/15/19

Last week, we analyzed addition and multiplication algorithms to explain why they work and how we can use them most efficiently. We took our final quiz and then took our first unit test of the year. This week, we will begin exploring using algebraic expressions to model different situations. We will then look to take a quiz over these topics.

Quiz 1.11-1.15 Study Guide KEY

8th Algebra Update 9/8/19

Last week, we explored representing addition and multiplication in different ways and practiced ways of working with fractions more easily. We took a quiz on these topics on Thursday. We then explored some different algorithms to perform addition and subtraction more efficiently. This week, we will continue to examine addition, subtraction, and multiplication algorithms to gain a better understanding of why they work and how we can use them. We are scheduled to take our last quiz of the unit on Wednesday and then take our first unit test on Friday.

Quiz 1.06-1.10 Study Guide KEY

8th Algebra Update 9/2/19

Last week, we connected the patterns we noticed on the addition and multiplication tables to the basic properties of arithmetic. We then took a quiz over sections 1.01-1.05 on Tuesday. On Wednesday, we began exploring how to work more with rational numbers. We compared and converted between fractions, decimals, and percents. This week, we will continue to work with rational numbers and look at different representations and patterns of addition and multiplication. We will look to take a quiz over these topics on Thursday. Then, we will begin to explore and break down some algorithms of addition and multiplication to see why they work.

Quiz 1.01-1.05 Study Guide KEY

8th Algebra Update 8/25/19

Last week, we use addition and multiplication tables to explore some important underlying patterns of each operation. We extended those patterns into negative integers, as well. This week, we will connect the patterns we noticed to the basic properties of arithmetic and then take a quiz over these topics on Tuesday. Then, we will explore patterns with decimals and fractions.

8th Algebra Update 8/18/19

Hello! Welcome to the 8th Grade Algebra web page. I will post an update like this weekly to summarize what we have done and preview what lies ahead. You will also find a weekly calendar updated daily with homework assignments. We had a great first two days of math class. We began by exploring a challenging problem called the handshake problem. Students also shared their methods for calculating the number of cars in a traffic jam. This week, we will begin to explore patterns of operations such as addition, subtraction, and multiplication. Though these are topics they have seen before, we will explore them more deeply to look for underlying patterns and develop useful strategies. We will then take a quiz over these topics. I am looking forward to seeing everyone at open house this Thursday night!
