• alg 1

    The 7th grade math algebra program emphasizes abstract mathematical concepts and their application. The students placed in this course, which is the equivalent of Algebra I at the high school level, are characterized by their excellent computational skills and demonstrated readiness for abstract mathematical reasoning. The curriculum familiarizes students with all the algebraic techniques necessary for higher level mathematics.

  • Unit 7: Advanced Linear Inequalities

    Posted by Alexa Schmidt on 2/18/2019

    Currently in Algebra 1, students are building off of the last unit to tackle more advanced linear inequalities and applications. We start the unit with absolute value linear inequalities, move on to graphing inequalities on the coordinate plane, and then applying them with systems of inequalities.

     

    To extend at home, can your child explain which option would be better?

    Option A: Your parents give you $100 now and $1 per day until the end of the school year for your successful completion of Algebra.

     

    OR

     

    Option B: Your parents give you $50 now and $2 per day until the end of the school year for your successful completion of Algebra.

  • Unit 6: Intro to Linear Inequalities

    Posted by Alexa Schmidt on 2/4/2019

    Currently in Algebra, students are learning how to create, apply, solve, and graph one-step and multi-step linear inequalities. We are also learning about compound inequalities that use intersections and unions. This unit is mostly review but is necessary to build a strong foundation for our next unit, advanced linear inequalities.

     

    To extend at home, ask your child to explain the difference between when a union is true and when an intersection is true. Can they come up with some compound statements that are true and false? Can you find examples of compound statements in the news?

    For example, tomorrow it will either rain or snow. Only one of these scenarios has to come true in order for the statement to be true.

  • Mini-Unit: Scatter Plots & Graphing Technology

    Posted by Alexa Schmidt on 1/9/2019

    In this mini-unit between now and exams, the students are exploring scatter plots - how to create them, how to find analyze them, and how to use them to make predictions. This is an exciting unit for the students because we do a hands-on candy activity to create a class scatter plot and we use our graphing calculators to visualize our scatter plot and find the line of best-fit. 

     

    To extend at home, look in the newspaper for scatter plots and ask your child to explain the correlation and what that means in the context of the story.

  • Unit 5: Equations of Linear Functions

    Posted by Alexa Schmidt on 1/7/2019

    In this unit, which covers sections 4.1 - 4.4 of the textbook, we look at the equations that create linear functions and the patterns we can find in them in order to generalize equations for all linear functions. We examine linear equations in standard form, slope-intercept form, and point-slope form and learn how to change between the forms. We finish up the unit with a study of parallel and perpendicular lines.

     

    To extend at home, find two parallel lines and ask your child to approximate the equations of the two lines, using estimated slopes and y-intercepts.

  • Unit 4: Linear Functions

    Posted by Alexa Schmidt on 12/20/2018

    In this unit, covering chapter 3 of the textbook, students are introduced to functions that create linear graphs. We focus on multiple ways to graph the functions (making a table, finding the intercepts, etc) and how to apply them to different types of problems (direct variation, arithmetic sequences, etc). This unit builds basic understanding of linear functions and slope before we get into the equations of linear functions in the next unit.

     

    To extend at home, create an arithmetic sequence (any pattern of numbers that uses addition or subtraction) and ask your child to create a simplified linear function to represent the sequence.

  • Unit 3: Applications of Linear Equations

    Posted by Alexa Schmidt on 10/19/2018

    In this unit of A1, students are taking the skills they learned in the last unit and applying it to real-world scenarios. We are learning about ratios and proportions, percent increase and decrease, and sales tax. A particularly hard section for students tends to be section 2.8 on literal equations and dimensional analysis - studying and practice problems are essential!

    To extend at home, have your child calculate tip or tax on a purchase.

  • Unit 2: Advanced Linear Equations

    Posted by Alexa Schmidt on 10/12/2018

    This unit in A1, students are reviewing their linear equation skills and applying them to more difficult problems. We have learned that linear equations can have zero, one, two, or infinitely many solutions and how to solve absolute value equations. 

    The students were especially good at teaching each other applications of absolute value equations. The students were put into groups of two or three and given a sample problem and explanation for different types of absolute value problems. Together they had to read and understand the material and apply it to new problems. They worked well together and were able to act as true mathematicians - figuring things out for themselves!

    To extend at home, ask your child how fluxuating temperatures throughout the day can be represented by an absolute value equation.

  • Unit 1: Expressions, Equations, and Functions

    Posted by Alexa Schmidt on 9/26/2018

    Currently in A1, the students are learning the foundations of Algebra - algebraic expressions, equations, and functions. We are spending a lot of time with the Properties of Numbers and the relationships between functions and equations. Check out this hilarious video that explains the concept of a function: Meat-a-Morphosis

     

    To extend at home, ask your child to explain the similarities and differences between a relation, a function, and an equation.
