Very hands-on, fun, and engaging math center. My students LOVE this center. Using half of the plastic Easter eggs, you can create any counting variation that fits your needs.
I have created a worksheet to go along with this center in order to add a concrete informal assessment piece to it.
I also use this center to reinforce AB, ABB, ABC, AABB, etc. patterns.
Feel free to contact me for other versions of this worksheet in order to fit your center needs.
