8th Grade Math Worksheets (Grade 8 - For Ages 13 to 14)

Math in the 8th grade begins to prove more substantial as far as long range skills students will use and need. Students work towards mastery with the basic order of operations. Expressions, function tables, probability as begin to work at the core of this grade level. We also have another 30 or so "Do Now" math worksheets for grade 8 students here.

Beginning of the School Year

These worksheets are building off of last year's skills. They are part of the 8th grade curriculum, but they are usual learned in one shot. In our experience it is because they are very concrete skills that don't need much explanation.



  1. Compare Exponents - Have students compare the end value of these exponents.
  2. Function Tables - Input the variables into the equations and see what comes out.
  3. Math Operations and Reasoning - Every problem is missing three to four operators. Make each equation true.
  4. Surface Area - You are given 2 to 3 dimensions or measures of a rectangular prism and asked to find all the others. Sometime math has a cool power about it!
  5. Circle the Irrational Numbers - If you can write a number as a fraction or simple ratio, it's rational. Take a quick glance at these specimens and determine if they are rational.
  6. Operations with Exponents - We take exponents out for a walk and throw them into 2 and 3 step problems.
  7. Scientific Notation - Meeting up with our friend times ten to the exponent. Write each number using scientific notation then move on to standard format. Pay attention to number 3. What's up with that one?
  8. Venn Diagrams - We always knew that Venn Diagrams had a huge place in the Language Arts classroom, but they do the same thing when organizing data. Venn Diagrams should be used in the math classroom just as much.

Midyear Problems

These problems actually take more time to understand and may take two or three passes to really catch on.

  1. Evaluate Expressions - This is a quick plug and chug activity to test student skills.
  2. Writing Expressions - Convert number sentences to expressions. A really good skill to have.
  3. Rewriting Fraction Equations - Solve for the variable in each case. Please note there are two- three step problems in the batch.
  4. Order of Operations - Remember good ole' PEMDAS for this one. There are three steps max for each one.
  5. Surface Area - You will also be asked to find other measurements of length.
  6. Determine the Slope of a Line - You will work off of points and actual lines on cooridinate graphs.

Advanced Skills

These are the skills that not everyone can grasp in just a few times going over it. These also happen to be the skills that many students have trouble with on standard tests.

  1. The Truth of Inequalities - Determine the truth value for ever inequality you come across. A simple T or F will do.
  2. Probability as a Fraction - Determine the probability of every event in the form of a fraction.
  3. Solve Simultaneous Linear Equations - This is always the point in algebra where kids say "What the heck is that?" Make sure they master this skill before moving on, it's critical.
  4. Monomial, Binomial, and Polynomial Operations - We take these sets and throw them through various operations. We concentrate mostly on products and quotients here.
  5. Graphing Linear Inequalities - These are the baby steps to full on graphing inequalities. At this point we are just looking for a directional line and point.
  6. Logarithms - We focus on the conversion and calculations with logs and log form.
  7. Using Pythagorean Theorem - We really give the Pythagorean Theorem a work out. First, determine if you have a 90 degree angle in the triangle. Second, find the length of a side and measurement all using the Theorem.
  8. Midpoints and Equations of Straight Lines - We give you two points on the path of a line. We then ask to find the midpoint of those two points on the line and the equation of said line. Who knew lines had such a personality?
