Both the teacher and the parents could instead focus on ways of incorporating the student's musical intelligence in learning algebra. The student will learn more and probably thank you for it. For instance, if there is a career day at school, jobs from each of the intelligences should be represented. Offer to come into your child's class and talk about the skills and intelligences you use in your job everyday.

Teachers are unfamiliar with their students so early in the year, and parental input will help speed the process of identifying intelligences along.
