We use Saxon math. I am Ok with it since I teach first grade. I am on a committee to help get our school's math scores up. The students do well up to third grade then they drop big time in grades 4 and 5. I was shocked to see how low they dropped. Our school is small with the same kids and one of each grade. I don't understand how the same kids who did so well dropped so low in math. Reading is still very good. Is there something with Saxon that is lacking or are our teachers not using Saxon as they should ? (they say they are). Our principal is not willing to change from Saxon. My husband says to write a letter to the company and complain their series is not doing what they say it will do. If you have good math scores what do you do? What math progam do you use?
