Student One has a good grasp of phonemic's. He was able to break apart and blend words without a problem. When it came to rhyming he struggled a lot. I would first start with a lesson about rhyming words. Once he has some information about what a rhyming word was, he would probably be able to figure it out since he has a good grasp of phonemic's. I would also have this student read simple rhyming books to become familiar with what rhyming words sound like. On his online Razzkids account I would assign him rhyming books to listen to as well.
