7th Grade Algebra
Last week, we continued working with linear functions in different forms. We practiced finding information such as slope and both of the intercepts and graphed those linear functions in various forms. We then applied linear functions to real-world situations and took a quiz over those topics. On Friday, we extended our knowledge of linear functions and explored linear systems of equations. This week, we will continue practice how to solve systems using different methods including substitution, graphing, and linear combinations (elimination). We will then look to take a quiz over those topics.

Last week, we extended our knowledge of slope to consider equations of linear functions. We explored different forms of linear functions including point-slope, slope-intercept, and standard form. We practiced converting between the forms and finding information regardless of the form of the linear equation. We also practiced graphing linear functions written in different forms. This week, we will continue to practice these skills as well as use linear functions to model different scenarios. We will then look to take a quiz over these topics. After our quiz, we will begin to explore systems of equations.
I hope everyone had a wonderful break! In the week leading up to winter break, we used our knowledge of graphing functions to create math artwork. We used an online graphing tool called Desmos. The students did a fantastic job! This week, we will continue with our unit on linear functions. We will transition from slope to equations of lines. We will work with and graph linear functions in multiple forms.

Last week was a busy week for us. We explored the concept of collinear points and then reviewed for and took a quiz. On Thursday, we reviewed, and then we took our semester 1 final exam on Friday. This week, we will use what we have learned so far this year to complete some challenges using an online graphing tool called Desmos. We will then use mathematics to create artwork for a project to finish out the week. I hope everyone has a great holiday season!
Last week, we reviewed slope and rate of change. This week, we will explore collinearity before reviewing and taking a quiz over these topics. On Thursday, we will review for our final exam and we will take our first semester final exam this Friday, 12/13. Students have a study guide and instructions on how they can be preparing for the final exam.
I hope everyone had a fantastic Thanksgiving! In the shortened week before break, we reviewed and took our unit 3 end-of-chapter test. This week, we will begin a short section reviewing slope and rate of change. Students should also be preparing for their semester 1 final exam. The date is still being finalized, but it is likely the final will either be the end of the week of 12/9 or the beginning of the week of 12/16. We discussed in class ways students can begin to study.
Last week, we explored direct and inverse variation, were introduced to a handful of new types of function families, and learned how to translate those different functions. We took a quiz over those topics on Friday. This week, we will review and then take our unit 3 end-of-chapter test on Tuesday. I hope everyone has a fantastic break!
Last week, we explored the relationship between equations, solutions, points, and lines. We also looked into what happens when multiple lines are graphed and there are intersections. We took a quiz over these topics on Friday. This week, we will begin to explore the difference between direct and inverse variation as well as other nonlinear function families such as quadratic, cubic, linear absolute value, and square root functions. We will then look to take a quiz over these topics.
Last week, we reviewed plotting data using scatter plots and analyzed positive and negative association. We also explored the very important difference between correlation and causation. We then took our second quiz of the unit and our unit 3 mid-chapter test on Friday. This week, we will begin the our next unit, which will cover the second half of chapter 3. We will begin by exploring the relationship between equations, points, lines, and solutions. We will then review graphing by plotting points and look to take a quiz over these topics.
Last week, we explored different representations of statistical data and practiced creating and interpreting those representations. We worked with mean, median, and mode as measures of average, frequency tables, dot plots, histograms, stem-and-leaf plots, box-and-whisker plots, and two-way tables. This week, we will explore scatter plots and correlation, and discuss the important difference between causation and correlation. We will then look to take a quiz over these topics on Wednesday and take our unit test on Friday.
It was great to see everyone at parent-teacher conferences! Last week, we practiced graphing related quantities to represent different situations. We also looked at graphs to determine the mean of each part and piece together what was happening. We then reviewed and took our quiz on Thursday. This week, we will begin exploring statistics and graphical statistical representations. We will review mean, median, and mode, dot plots, histograms, and box-and-whisker plots. We will also look into categorical data and interpret two-way frequency tables. Finally, we will look to explore scatter plots before taking a quiz over these topics.
Last week, we began the first part of our third unit by exploring transformations and coordinate notation, solving absolute value equations, and deriving the distance formula through the Pythagorean Theorem. This week, we will continue practicing those topics as well as creating qualitative graphs to represent different situations. We will then look to take a quiz over those topics. I am looking forward to seeing everyone at parent/teacher conferences at the end of the week!
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.
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.
Last week, we practice writing, evaluating, and simplifying algebraic expressions. We concluded the week by taking a quiz over these topics. This week, we will focus mainly on strategies to solve equations and the meaning of solutions to equations. We will then look to take a quiz over these topics.
Last week was an abbreviated week in math class due to Outdoor Ed. I was along for the Thursday-Friday session, and it seemed like students had a great time. This week, we will continue writing, simplifying, and evaluating expressions. We will conclude those topics by taking a quiz.
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 only have one day of normal math class due to Outdoor Ed. I hope everyone has a great time!
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.
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.
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.
Hello! Welcome to the 7th 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!
