I created these timed tests to use with my kindergarten class during the second half of the year when we really start to practice addition and subtraction. My students seem to retain material best when I make some sort of game out of it, hence the timed test aspect. Included in this PDF:
Each page has two identical timed tests. I eventually intend to make subsequent versions to mix it up, though I don't think my students are thinking too into the fact that I'm giving them the same quiz every week. I assign students the timed tests in the above listed order. I give students one minute from the time they turn their timed test over. I then move students who pass (get all 10 questions correct in time) on to the next lower subtraction timed test. After they complete all of them, on to teen addition they go!
Check out my other timed tests if you are in need of options. I have lower addition and subtraction, teen addition and subtraction, mixed lower, and mixed teens!
