We realized that we had a couple of alphabet sets that we were not even using and they had so many categories! So I brought them home this weekend to sort them into categories and realized that the back sides of the letter dividers were also blank with a laminated area for labeling.
So the sorting began!
And when it was all said and done....I ended up wth 13 categories!!!These are going to be perfect for teaching categories to my students and I didn't even have to purchase anything!! :)
