Letter to teacher concerning child's academic difficulty

Dear Mrs. Hatcher

My son, Randy, tells me that he is greatly enjoying school so far this year. He has many good things to say about both you and his classmates.

The problem which has, as you know, become apparent lately, is that Randy seems to be struggling with math and is falling behind in this subject. I am looking for any ideas or thoughts from you as to how we might help him gain a better grip of the concepts of math before he falls farther behind than he seems to be at present.

I would appreciate your thoughts and suggestions. Please call me at your earliest convenience so we can discuss this problem. Thank you again for your time.
