Picture18th Grade Math Curriculum and Common Core Math Standards

As stated in corestandards.org:

In Grade 8, instructional time should focus on three critical areas:

(1) Formulating and reasoning about expressions and equations, including modeling an association in bivariate data with a linear equation, and solving linear equations and systems of linear equations;

(2) Grasping the concept of a function and using functions to describe quantitative relationships;

(3) Analyzing two- and three-dimensional space and figures using distance, angle, similarity, and congruence, and understanding and applying the Pythagorean Theorem.

8th Grade Common Core Math Standards

The common core breaks 8th grade math down into 5 section as listed below. Click on the links to view more information on the specific standard.

The Number System

Picture58th Grade Essential Concepts

While all math skills and concepts learned in 8th grade are important, this section focuses on a few key math concepts that MUST be reviewed, practiced, and understood in order for students to successfully build on their math knowledge and increase their mental math speed going forward.

Many times if a student struggles in high school it is because he/she still does not have these essential concepts down from middle school or even earlier!

Some of these concepts may not have been taught in 8th grade but they should remain the main focus of review.

1. Negative Numbers

6th graders and up should known how to add, subtract, multiply, and divide positive and negative numbers.

Negative numbers, in particular can be tough for kids to ‘wrap their heads’ around. Check out the Kahn Academy lessons to learn everything you need to know!

Negative numbers introduction: Mysterious negative numbers! What ARE they? They are numbers less than zero. If you understand the nature of below zero temperatures, you can understand negative numbers. We’ll help.


8th grade math negative number essential red flags:

  • Spends a lot of time thinking about problems that should be mastered.
  • Expresses stress or anger when working with negative numbers or subtraction, in general
  • Relies too heavily on the calculator to compute values
  • Loves addition but gets stuck when a number has a negative sign.

Parent / Teacher Tips:

  • Review and test your students speed and accuracy with adding and subtracting
  • Connect to real life like digging a hole, temperature, diving under water, and owing money.

2. Order of Operations (a.k.a “PEMDAS”)

PEMDAS = Please Excuse My Dear Aunt Sally

…is the fun way to remember the steps we have to follow to solve math problems: Parentheses, Exponents, Multiplication & Division, Addition & Subtraction.

PEMDAS is what helps students know what to tackle first in a problem like this: (5 – 1)2 + 3 • 4 – 2 + 6 / 3

If one does not follow the order of operations, he or she will come up with an answer, but it will be wrong! Answer to expression above = 28. Master this essential 8th grade math concept by checking out the Kahn Academy lessons bellow.

Introduction to order of operations: This example clarifies the purpose of order of operations: to have ONE way to interpret a mathematical statement.

8th grade math order of operations essential red flags:

  • Does not know what the purpose of PEMDAS is.
  • Gets different answers after solving same problem multiple times.
  • Spends a lot of time thinking about problems that should be mastered.
  • Expresses stress or anger when working basic algebra problems.
  • Reports not having enough time on assignments, quizzes, & tests

Parent / Teaching Tips:

  • Review & test your child’s speed & accuracy with order of operations.
  • Make practicing a game.

3. Solving multi-step algebraic equations

Middle schoolers see algebraic problems getting more complex. Students need to be able to solve – without error – equations and expressions that requires multiple steps.

Single-step algebra: 3x = 6

Multi-step algebra: 3x + 2 = 4x – 8

Here we provide another amazing resource by Kahn Academy teaching you eveything you need to know about solving multi-step equations.

Introduction to solving an equation with variables on both sides: Sal solves the equation 2x + 3 = 5x – 2.

Red Flags

  • Spends a lot of time thinking about problems that should be mastered.
  • Expresses stress or anger when working multi-step problems
  • Takes a lot of steps that do not get them closer to solving.
  • Reports “not having enough time” on math homework, quizzes, or tests.
  • Attempts to have calculator compute values for him/her

Parent / Teaching Tips:

  • Review & test your child’s speed & accuracy with PEMDAS
  • Make practicing a game

4. Graphing Lines

Linear equations are present throughout algebra and students in middle school need to master this skill to be ready for more complexity in high school.

Lines can show up in a few different forms, but the most popular one is “slope-intercept form” or y=mx + b.

In y=mx + b, x and y are the variables that represent points on the graph, m is the slope (rise over run), and b is the y-intercept (because if you plug in 0 for x, you are left with b or the point (0, b).

Example graphed at right: y = – x + 6

Make sure you have these concepts mastered by clicking here! Here you will learn everything you need to know about the graphing lines essential 8th grade math concept.


Red Flags:

  • Spends time thinking about problems that should be ‘easy.’
  • Expresses stress or anger when graphing linear equations.
  • Takes a lot of steps that do not get them closer to solving.
  • Reports “not having enough time” on math homework, quizzes, or tests.
  • Attempts to have calculator compute graph line for him/her.

Parent / Teaching Tips:

  • Make practicing a game: create a giant ‘grid’ on the floor and practice graphing points with your whole body standing where the point should be!
