I have a student in my class this year that is very weak in both reading and spelling. The strange thing is that when he reads, he is sometimes able to read some of the bigger words, yet he has trouble with the simple words like 'at', 'with', etc... This student also knows his sounds and many phonetic rules, yet I can barely read his work. Usually if I point out a mistake in his work, he can fix it. But again he can't spell simple words like 'good'. Any ideas on how I can help this student become a better reader and speller?
