I got in gear early this year and made up two assessment/practice activities for standardized testing. If you give the IOWA, the CAT, or the Terra Nova, your students can practice answering questions that are worded similarly to the test they will take. There is also a page for learning how to bubble properly. My kids were terrific bubblers on our real test which was the first week of April. Whew!
You can find these resources in my TpT store! They are meant to be a practice, so they are not as lengthy as the real test. Kids do not need over exposure to taking a test, but they do need experience. I think these resources do that! Thanks! (click on the pics to view on TpT).
