They can be used as extra practice for those who need it, or as additional challenges for those who want to gain an edge.

The worksheets being introduced to you here are all completely free to download and use, and they cover everything an 8th grader needs to know about math. Here goes.

## 1) Easy Fractions Into Decimals Worksheet

In order to truly understand the relationship between fractions and decimals and percentages, it is worksheets like this one that are key.

In this worksheet, 18 different fractions are presented where the denominator is a multiple of 10.

It’s a great starting point for an 8th grader, because all the student has to do to convert the fraction to a decimal is note down the numerator but with the decimal point moved to the correct place.

## 2) Multi-Step Equations: Integers Worksheet

Math students need to get to grips with basic algebra in 8th grade, so that when they progress in later years to learning about simultaneous equations, they understand the processes involved.

In this worksheet, 8 equations are presented, each with one number represented by a letter, and the student is to deduce what number is represented by the letter.

It’s a logical process and all the student has to do is treat each side of the equation the same until the unknown number can be identified.

There is some room on the worksheet for the kids to do their working out.

## 4) Triangle Interior Angles Worksheet

8th graders need to be able to understand basic geometry. And understanding the angles and nature of triangles is key to this.

The 9 questions on the worksheet all require the student to find the unidentified angle.

This particular worksheet centers around the concept of the angles in a triangle always totaling 180 degrees.

And in addition to instilling this concept, the worksheet also has the students learning the convention nomenclature for noting angles.

## 5) Parallel Lines And Interior Angles Worksheet

Once an 8th grader has learned the various principles behind the angles formed by a straight line crossing two parallel lines, it’s easy to find out any unknown angles, as is required by the 8 questions in this worksheet.

More often than not the unknown angle either matches that of the angle provided or can be worked out by subtracting the known angle from 180 degrees.

## 6) Pythagorean Theorem And Identifying Right Angle Triangle Worksheets

While Pythagorean theorem is most frequently used to identify the length of the hypotenuse of a right angled triangle, it can also be used, as in this worksheet to identify whether, or not, a triangle is in fact a true right angle triangle.

In the first 4 questions on the sheet the length of all 3 sides of each triangle is provided, and the student needs to work out the square of each.

They could use a calculator, or you could get them to try doing it with mental arithmetic.

The remaining two questions require the students to use Pythagorean theorem to prove that two other triangles (not displayed) are true right angles, given the lengths of each side.

## 7) Finding The Volume Of Cones Worksheet

This is a great worksheet for 8th graders because it builds on math they have learned in previous years, and takes it one step further.

In all 8 questions, the student is required to calculate the volume of a cone, having been provided the radius of the circle face and the height of the cone.

First they have to find the area of the circle, as determined by squaring the radius and multiplying by pi. Then they need to multiply this figure by a third of the cone’s height.

This worksheet also presents a question written as a word problem, and it also asks the student to round their answer to two decimal places.

## 8) Mean, Median, Mode & Range Worksheet

When it comes to statistics, the most important concepts for kids to learn are the mean, median, mode, and range. And that’s where worksheets like this one come in.

This knowledge will also help the students in their science subjects, which will require them to interpret data.

There are 5 questions on the worksheet, which demonstrate multiple instances where these stats may be required.

What makes it tricky is that the figures provided in the raw data are not necessarily always presented in numerical order.

There’s no room on the worksheet for working out, so the student will need some scrap paper for working out the answers.

In order to access this worksheet, simply click on this link. There’s also an answer key provided.

## 9) Simplifying Fractions Worksheet

Smaller numbers are always easier to work with than larger ones, and that is why it’s very useful to be able to simplify fractions to their lowest terms.

And that’s where worksheets like this one come in.

The first 21 questions require the student to simplify the fractions presented by finding the lowest number that both the numerator and the denominator can be divided by.

The remaining 4 questions are a twist on the theme.
