Math Grade 8 – November 18 -22

We continue to work on understanding linear relationships by:

  • Graphing linear relationships
  • Identifying linear and nonlinear graphs
  • Classifying slopes of  lines
  • Determining the slopes of lines
  • Interpreting slopes of graphs describing realistic relationships
  • Writing and interpreting slope-intercept equations

Many students have not yet demonstrated mastery of basic multiplication and division facts and still struggle with multiplying and dividing multi-digit numbers.  Please help your child review these basic math skills regularly.

A good online resource for practicing math facts is at .

Apologies for the delay in posting student scores on PowerSchool.


Math 8  –  11/01/13

Students in Math 8 are continuing exploring basic algebra concepts, manipluating, solving and graphing linear equations (such as 3x + 4 = 40) and solving a system of two linear equations (such as5x – 2 = -3x + 14) by graphing and manipulating equations.  All students should be reviewing the   basic math facts on a daily basis to achieve instant recall of facts.

Note:  I am available for parent-teacher conferences for those parents who were unable to schedule a conference with me last week.  Please contact me to arrange a time.


Status of 8th grade Algebra I course                                                            21 October 2012

Dear 8th grade parents & guardians,

Following  the September 9th meeting regarding algebra instruction, we continued with instruction in beginning algebra, slowing down as needed to address specific gaps in students’ basic math skills and understanding.  Students have been attentive, but their retention of the material has been low and progress very slow.  It has become eminently clear to me that none of the students are really ready to succeed in a full-fledged Algebra I course.

After much consideration, Dr. Diaz and I have decided that the way best to support students’ success in mathematics is to set shelve 8th grade Algebra I and address students’ instructional needs through an integrated  8th grade math curriculum based on NM Common Core mathematics standards.

While this may come as a disappointment to some of you, please remember that Algebra 1 is not part of a typical 8th grade curriculum.  An integrated math course will cover foundational algebra concepts as well as number theory, geometry, and statistics and probability.  Here is an overview of the NM Common Core math standards for 8th grade.

The Number System

• Know that there are numbers that are not rational, and approximate them by rational numbers.

Expressions and Equations

• Work with radicals and integer exponents.

• Understand the connections between proportional relationships, lines, and linear equations.

• Analyze and solve linear equations and pairs of simultaneous linear equations.


• Define, evaluate, and compare functions.

• Use functions to model relationships between quantities.


• Understand congruence and similarity using physical models, transparencies, or geometry software.

• Understand and apply the Pythagorean Theorem.

• Solve real-world and mathematical problems involving volume of cylinders, cones and spheres.

Statistics and Probability

• Investigate patterns of association in bivariate data.

The standards are actually quite rigorous, and concepts we covered in the first quarter fit into the areas of Expressions and Equations and Functions.

Please feel free to contact me with any questions or concerns regarding this change of course.

In the meantime, I request your assistance in getting your child up to speed with basic math facts.  Fully two-thirds of the class has not yet demonstrated mastery of the  multiplication facts (a 4th grade expectation).  Students still struggling with these basic facts will continue to struggle in 8th grade math and beyond.


Warm regards,
