Sensory Numbers

I have a Kg student this year that is really struggling with naming and writing her numbers.  So I have been trying to add more sensory activities to her lessons. This week I made some numbers with fuzzy balls from Dollar Tree. It was super easy. I bought two bags, and it was enough to make numbers 0-9. We practiced naming, touching, and tracing the numbers. She also counted out manipulatives to match the numbers. Any thoughts? Comment if you have any other ideas that work with some of your struggling students.
