English writing is a sound code. The most efficient way to learn to write and read is to learn the sound symbols, i.e., the alphabet.
It is not enough to teach a child to recognize the letters in a book or on a screen. To internalize the connection between sound and symbol, the child learns to form the letter while saying its sound or sounds.

THE ALPHABET, HANDWRITING, PRONUNCIATION, SPELLING, and GRAMMAR.
