Addition Timed Tests 0-10 has two different timed tests for each addition set. Having two different versions helps prevent copying and memorization. This layout will help you save paper but isn't too small for your younger students.
I give students one minute to complete each test. When they complete the test with 100% accuracy they can add a color sticker dot to their bubble gum machine. I write which test they have passed on the sticker. I purchased a gum ball machine and they get a piece of gum after passing each test.
It is super easy and fun. Your students will love it.
