I'm looking for phonics based materials for teaching adult beginner ESL students. Does anyone know of some good basic materials such as matching card games for learning spelling patterns.
You might try progressive phonics - http://www.progressivephonics.com/phonics-books/beginner-phonics-books But I hear you. Almost all phonics materials are created for children and childish. But I do think you can find lettered flashcards online where students use beginning, middle and ending spellings to create and sound words.
