ABC Train Uppercase to Uppercase Letter Matching File Folder ActivityChugga, chugga, choo choo! All aboard the ABC Train!I created this interactive file folder activity for my toddler who loves anything and everything train! He loves putting the color back on the train and matching the letters. I used two commonly seen different fonts. This resource is great for letter recognition, fine motor skills, hand eye coordination, and is a skill little ones need to master before learning letter sounds.
