Match Uppercase and Lowercase Letters

Every letter has two forms — a big uppercase letter and a small lowercase letter. A letter appears, and the child taps the matching letter in its other form. It is a calm, friendly way to recognize the same letter as both big and small, with no timer and no score. Aligned to Common Core RF.K.1.d — recognizing and naming all upper- and lowercase letters of the alphabet.
