These phonetically-controlled word lists have been created by HHBAOGPE for oa. They include a poster that can be printed and shared, as well as word lists that have blends, digraphs and clusters, and 2-syllable words with oa. A great resource to supplement any classroom's study of oa in their spelling words with the ability to reach every student's level by varying the level of challenge a child needs. Also a great resource for any teacher who utilizes the Orton-Gillingham Approach.
