This is a 34 question test that covers 7th grade math common core rational numbers, expressions, and equations. This covers a range of problems from basic calucations with integers to solving and determining inequalities and equations.
I have given this test to my 7th graders. I normally don't give a unit test - every test I give covers everything that we have learned from the beginning.
This can be downloaded as a Word document so you can modify as needed. If you have trouble with the formatting, a PDF version is located on the last page.
Hope this helps!
