This is a 28 page set that covers many number skills from 1 to 1 matching to making sets different ways to writing number words. Given the option of skills, this center spans grade levels PreK through 2nd grade, but also works for differentiating in one classroom (we all know the spectrum of levels we get!).While you are grabbing this freebie please become a follower at my TpT store (if you aren't already!) and, once you have checked it all over I would LOVE it if some of you would be so kind to leave feedback for it there. You can print and laminate these boards for center use. Also, I recommend using velcro, especially for the number matching boards.
