**Free worksheets for evaluating expressions with variables**

With this worksheet generator, you can make printable worksheets for evaluating simple variable expressions, when the value of the variable(s) is given. There are three levels, the first level only including one operation. For example, the student might find the value of the expression 2(*t* − 5), when *t* has the value -6.

These worksheets suit best grades 6, 7, and 8, including pre-algebra and algebra 1 courses.

To customize the worksheets, you can control the number of problems, difficulty level, range of numbers used (you can include negative numbers and decimals), workspace below the problems, border around the problems, and additional instructions.

## Basic instructions for the worksheets

Each worksheet is randomly generated and thus unique. The **answer key is automatically generated** and is placed on the second page of the file.

You can use the generator to make worksheets **either in html or PDF format** — both are easy to print. The html worksheet has the advantage that you can save it directly from your browser (choose File → Save) and then later *edit it* in Word or other word processing program.

Here are some quick links for ready worksheets. Refresh the worksheet page to get another of the same kind, until you are happy with the problems & layout.

**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.
