About the Mixed Operations Worksheets

On a sheet with only one operation, a student can stop reading the sign after the first problem. Mixed practice takes that away. It is the quickest way to find out whether facts are really known or are being produced by habit.

The sets step up in the order the operations are taught: Set A mixes addition and subtraction facts, Set B uses 2-digit numbers, Set C mixes multiplication and division facts, and Set D has all four. The sets are fixed, so a sheet can be repeated to see progress.

Missing Signs turns the task around: the numbers and the answer are given and the student works out which operation connects them. In and Out Tables apply one rule to several numbers, then ask for the input when only the output is given, which is the first step toward thinking about inverse operations.

For practice on one operation at a time, see the addition, subtraction, multiplication and division worksheets.

Frequently Asked Questions

What are mixed operations worksheets?
Worksheets where addition, subtraction, multiplication and division appear together on one page, so the student has to notice which operation each problem asks for.
What grade are these for?
Second to fifth grade. Sets A and B use only addition and subtraction, for 1st to 3rd grade. Sets C and D and the 60-fact sheet need multiplication and division facts, which are 3rd grade and up.
Are these the same as order of operations?
No. Each problem here has one operation. Problems with several operations in one expression are on the order of operations worksheets.
Do the worksheets have answer keys?
Yes. Every sheet is a two-page PDF with the answer key on the second page.
