I have a new items in my TPT and TN store that I am very excited about. They are muffin tin sorting labels. They are designed to be cut with a 2" circle punch and placed in the bottom of muffin tins to assist sorting of objects on those days when you want to provide a set of basic skills sorting standards. (Most times I like for my Little People to come up with sorting categories on their own, but some days I want to check their understanding of certain concepts and will use these labels.)
There are several types of sorting labels in this set: Upper case letters, Lower case letters, Numbers, Colors and Shapes.
