 You can help a child improve their understanding of uppercase and lowercase letters by playing a matching game. For this activity, all you need are some little cards or pieces of paper in two different colors. Then, you can write uppercase letters on one of the colors and the matching lowercase letter on the other color. You can place the uppercase letters down, making sure to spread them apart a little to give some room. Then, you can give the lowercase letters to the child and ask them, can you place these lowercase letters next to their matching uppercase letters and the child can match the letters. By matching uppercase and lowercase letters, a child improves their understanding of the alphabet.
