This document is a learning tool about long vowels. It contains interactive exercises and examples to teach readers about vowel combinations that make long vowel sounds. The main rules covered are that "ee" makes the long e sound, a single "e" at the end makes a long e sound, a single "y" at the end makes a long i sound, an "e" at the end of a word makes the first vowel long, and when two vowels are together the first vowel is long. It also discusses vowel combinations like "igh", "eigh", "ow", "oo", and "ew" that make specific long sounds.
