Now that your child has mastered the 26 lowercase letters, it's time to introduce capital letters. It's also time to learn the sounds of the vowel letters a, e, i, o and u, which are highlighted in the Pre-Reader Workbook Steps 10, 11 & 12.  Those vowel sounds are emphasized in the storybook Swim With Dolphins, while capital letters are featured in Camper Kim. Cap off the learning experience with star stickers.
