These four worksheets work on the oy and oi diphthong sounds. There is a cut and paste, a follow directions, a comprehension page, and a word search. I try to keep the other words in the worksheets at about a first grade level. I hope this is helpful. I have other worksheets on other vowel sounds on my teacherspayteachers store, Becky's Classroom Products. Thanks so much and have a good school year. Feedback is so appreciated!
