I have had a wonderful school year with my 26 third graders all of whom were bilingual. Most of my students were Chinese Americans with two from India. I used very engaging interactive strategies with my students throughout the year. They have responded to my teaching strategies very well, and made a lot of progress in all content areas. To my surprise and disappointment, my school principal informed me that she received a letter signed by most of the parents of my students stating that I did not teach their enough math. In the letter, they indicated the previous year students came home with a lot of homework and completed a large number of worksheets, while this year they have been given fewer worksheets. I explained to my principal that I was more interested in using math manipulatives and meaningful real world math problems than repetitive worksheets. What disappointed me (or hurt me) the most was that I have had four meetings with all the parents, and they did not raise any concerns in these meetings. Why would they directly go to the principal? What did I do wrong? Is this cultural? How should I respond to these parents?
