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.
