R.D.
Our daughter is in day care now. They have a wonderful structure. They have work sheets to complete that include writing their letters-upper and lower case, numbers, matching, which are different, etc. Our day care also has a bible story each day, if that is something you might be interested in.
If you check out the day care centers in your area you might be pleasantly surprised how they mirror a school setting. Our 'school' has three facilities; in Forney, Mesquite/Sunnyvale and Garland, although I am not sure where the Garland facility is located.
In our district we have the same program as far as district-preschool so I feel like we are penalized a bit. Since we can afford day care we don't have the option of the school facility.
In the day care setting you have the social interaction that is different than at home.
Good luck in your search.
