I created these timed tests to help build fluency with my students! We give a pre-test and post-test with mixed addition and subtraction and I wanted something to help students gain confidence between those two tests. I made progressively harder timed fluency pages. There are pages with four, eight and twelve problems for addition and subtraction separately and then a full page of both addition and subtraction with 24 problems.
There are two versions of the eight, twelve and full page tests. One version has the answer space last while the other version has the answer space first.
