Turn any multiple choice activity into test prep with practice bubbles. As a third grade teacher, this is the first year that my students take any sort of standardized test. WIth those tests comes bubbling in answers and transferring from booklet to answer sheet. This can be difficult for some students. I hope this freebie will help your students feel more confident as they prepare for standardized tests! There are 2 1-20 answer sheets in order to conserve paper.
