When  your child has a homework assignment, don't try to teach it to him.  Do the assignment with him instead.  You do the assignment as he does the assignment.  You have your sheet of paper and he has his sheet of paper.  Talk out loud as you do the assignment so your child can hear how you organize your thoughts.
 

MATH
Do the problem step by step on your paper as your child does it on his paper.  Don't say, "Now try one all by yourself."  Continue doing the problems with your child unless he tells you he would like to do a problem by himself or that he can finish the assighment alone.  If he gets some answers wrong, have him copy your answers but don't go back and teach him how to do those problems.  Just keep going on but slow down your pace.  You may be going too fast for your child to grasp what you are doing.  Writing the problems on your paper also helps your child see how to organize and set up a paper.
 

READING
Read while your child reads.  Read slowly, with expression, directly into his ear.  She should be able to say ec word as she hears it.  Don't ask him questions after you have finished reading.  If you want her to think about what she has read, you think about the story out loud.  Just as her to listen as you recap he the story from beginning to middle to end.  She may want to make comments about the story or passage and may even want to ask you questions about it.  Don't judge her questions - just answer them.
 

WRITING A REPORT OR ANSWERING UNIT QUESTIONS
You write the report or write the answers to the questions on your paper while your child writes the answers word by word on his paper.  If your child wants to change something, then change it.  think out loud as you are writing these assignments so he can see how you're finding the answers and organizing it.  Don't question him or have him repeat ideas back to you.  If your child has difficulty with handwriting, make your answers as short as you can.  Sometimes one word answers will do.
 

SPELLING
Let your child give you the test and correct it from his word list.  Miss some words on purpose, expecially the ones you are sure will cause him the most trouble.  Let her know you are going to miss some words before you take the test.  Take the test again to give her more practice, missing different words and also some of the same words.
