First, students learn what vowels are. Then they are asked to color in the vowels in the segments on Val the Worm with a blue crayon. At the bottom of the page, they color in the Lil the Ladybug sections with vowels. All the other sections on each bug can be colored any color students want. It's a great way to learn how to identify vowels so students can work on sounding out vowel sounds and become better readers.
