I am tutoring a little boy in first grade, and he is having trouble with some beginning blends and digraphs. For example, he confuses "ch", "sh", and "th" alot and he has trouble with "br", "tr", "str", etc. What are some different activities I could do with him to help this? Thanks! By the way, he also has trouble with the soft c and soft g concept. Is there anything I could do with that? Thanks!
