This pack includes 31 timed math tests using standard numbers. It does not have a theme so you can decide what reward to give your students when they achieve a level. The timed tests are mixed addition and subtraction facts to 20. Each timed test features 20-25 different problems. They are aligned with Common Core so your students will be adding and subtracting math facts within 20. There are also instructions of how to make a Folder and a set of trackable front covers to put on the folders. My students love it!
