**Free Math Worksheets for Grade 7**

This is a comprehensive collection of free printable math worksheets for grade 7 and for pre-algebra, organized by topics such as expressions, integers, one-step equations, rational numbers, multi-step equations, inequalities, speed, time & distance, graphing, slope, ratios, proportions, percent, geometry, and pi. They are randomly generated, printable from your browser, and include the answer key. The worksheets support any seventh grade math and pre-algebra programs, but have been specifically designed to match Math Mammoth grade 7 curriculum.

The worksheets are randomly generated each time you click on the links below. You can also get a new, different one just by refreshing the page in your browser (press F5).

You can print them directly from your browser window, but first check how it looks like in the "Print Preview". If the worksheet does not fit the page, adjust the margins, header, and footer in the Page Setup settings of your browser. Another option is to adjust the "scale" to 95% or 90% in the Print Preview. Some browsers and printers have "Print to fit" option, which will automatically scale the worksheet to fit the printable area.

All worksheets come with an answer key placed on the 2nd page of the file.

In seventh grade, students will study pre-algebra topics, such as integer arithmetic, simplifying expressions, the distributive property, and solving equations & inequalities. They continue studying ratio and percent and learn about proportions. Please note that these free worksheets do not cover all 7th grade topics; most notably, they do not include problem solving.

### Introduction to algebra

*The worksheets in this introductory section correspond with Math Mammoth Grade 7, Chapter 1, and don't involve negative numbers.*

**Order of operations**

**Expressions**

**Equations**

### Integers

**Number line graphs and simple inequalities involving integers**

**Addition and subtraction**

**Multiplication & Division**

**Primary Grade Challenge Math** by Edward Zaccaro

A good book on problem solving with very varied word problems and strategies on how to solve problems. Includes chapters on: Sequences, Problem-solving, Money, Percents, Algebraic Thinking, Negative Numbers, Logic, Ratios, Probability, Measurements, Fractions, Division. Each chapter’s questions are broken down into four levels: easy, somewhat challenging, challenging, and very challenging.

**Many operations etc.**

### One-step equations

### Rational numbers

**Convert decimals to fractions and vice versa**

**Decimal Addition and Subtraction**

**Decimal Multiplication and division**

**Key to Decimals Workbooks**

This is a workbook series by Key Curriculum Press that begins with basic concepts and operations on decimals. Then the books cover real-world uses of decimals in pricing, sports, metrics, calculators, and science.

The set includes books 1-4.

**Fraction addition and subtraction**

**Fraction multiplication and division**

**Key to Fractions Workbooks**

These workbooks by Key Curriculum Press feature a number of exercises to help your child learn about fractions. Book 1 teaches fraction concepts, Book 2 teaches multiplying and dividing, Book 3 teaches adding and subtracting, and Book 4 teaches mixed numbers. Each book has a practice test at the end.

**Scientific notation**

**Complex fractions**

### Equations and inequalities

**Key to Algebra Workbooks**

Key to Algebra offers a unique, proven way to introduce algebra to your students. New concepts are explained in simple language, and examples are easy to follow. Word problems relate algebra to familiar situations, helping students to understand abstract concepts. Students develop understanding by solving equations and inequalities intuitively before formal solutions are introduced. Students begin their study of algebra in Books 1-4 using only integers. Books 5-7 introduce rational numbers and expressions. Books 8-10 extend coverage to the real number system.

### Constant speed, time, and distance

### Graphing & Slope

**Real World Algebra** by Edward Zaccaro

Algebra is often taught abstractly with little or no emphasis on what algebra is or how it can be used to solve real problems. Just as English can be translated into other languages, word problems can be "translated" into the math language of algebra and easily solved. Real World Algebra explains this process in an easy to understand format using cartoons and drawings. This makes self-learning easy for both the student and any teacher who never did quite understand algebra. Includes chapters on algebra and money, algebra and geometry, algebra and physics, algebra and levers and many more. Designed for children in grades 4-9 with higher math ability and interest but could be used by older students and adults as well. Contains 22 chapters with instruction and problems at three levels of difficulty.

### Ratio

### Proportions

### Percent

**Key to Percents Workbooks**

Key to Percents first emphasizes mental computation and estimation skills--since most work with percents is done without pencil and paper. Then students are taught to solve percent problems using equal fractions and decimal multiplication. Finally, percents are used to solve word problems in a variety of applications. Key to Percents assumes only a knowledge of fraction and decimal computation. Book 1 covers Percent Concepts. Book 2 covers Percents and Fractions. Book 3 covers Percents and Decimals.

### Geometry

*Area **- these worksheets are done in the coordinate grid.*

*Volume & surface area*

*Since these worksheets below contain images of variable sizes, please first check how the worksheet looks like in print preview before printing. If it doesn't fit, you can either print it scaled (such as at 90%), or make another one by refreshing the worksheet page (F5) until you get one that fits.*

**Key to Geometry Workbooks**

Here is a non-intimidating way to prepare students for formal geometry. *Key to Geometry* workbooks introduce students to a wide range of geometric discoveries as they do step-by-step constructions. Using only a pencil, compass, and straightedge, students begin by drawing lines, bisecting angles, and reproducing segments. Later they do sophisticated constructions involving over a dozen steps-and are prompted to form their own generalizations. When they finish, students will have been introduced to 134 geometric terms and will be ready to tackle formal proofs.

Corey Hague PT1420 M1 Unit 1 Unit 3: Homework Assignment 1 10/2/14 Short Answer’s 5. What two things must you normally specify in a variable declaration? The variable’s name and the variable’s data type 6. What value is stored in uninitialized variables? Zero Algorithm Workbench Review Questions 3. Write assignment statements that perform the following operations with the variables a, b, and c. a. Adds 2 to a and stores the result in b b = a + 2 b. Multiplies b times 4 and stores the result in a a = b * 4 c. Divides a by 3.14 and stores the result in b b = a / 3.14 d. Subtracts 8 from b and stores the result in a a = b - 8 4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2. What value will be stored in result in each of the following statements? a. Set result = x + y = x++-y b. Set result = z * 2 -4 c. Set result = y / x 4-8=-4 d. Set result = y – z ++w+y 5.
