Do your little ones know the color of a banana or the color of a flamingo ? If they are just learning to tell colors, "Colors for Preschool" is a great app to introduce them to colors. "Colors for preschool" is a beautiful app going through all the basic colors preschoolers need to know, plus has a collection of real life colorful pictures. This introduces preschoolers to help identify colors around them. Audio for this app is provided by a little kid. Great for preschoolers & montessori's and kids playschools. This app is simple to use and no help is needed from a parent or a teacher. Good for kids sitting in the car - flipping through pictures and learning colors.
