This pack of word sorts provides practice for students ready to learn about “abstract vowel” combinations or diphthongs. Concepts include comparing the sounds that say /aw/, /ow/, and /oy/ as well as /oo/. Each of the 4 sorts has a list of 15 words that can be used for a variety of purposes from weekly spelling work to intervention sessions focusing on phonics rules. The worksheets are meant to be cut so words can be glued in student notebooks or kept in envelopes to be brought out for review throughout the week. This resource can be used for word study in classrooms first through fifth grade or in intervention work for students of all ages. Great for teachers and parents utilizing the Orton Gillingham methodology.
