The free educational app for children, ABC Songs: Kids Nursery Rhymes, has been designed for children from toddlers all the way to preschoolers and kindergartners. It can be used at home or at school. The app is based on the popular nursery rhyme, which is a set of poems that children learn by hearing them spoken. There are many different themes in the ABC Songs: Kids Nursery Rhymes app. The themes include the alphabet, numbers, phonics, colors, animals, birds, and more. Each theme has a set of flashcards. When a child is learning the alphabet, the app will show a picture of the alphabet and the phonics. The child will learn the sound of each letter and the letter-to-sound rule.
