Uppercase and lowercase letters are two forms of the same alphabet letters. Young learners often call them big letters and little letters. Matching A to a, B to b, and C to c helps children recognize that both forms make the same letter sound.
This skill matters because it supports reading, writing, and spelling from the very beginning.
