It sounds like I have been at your dinner table. My daughter started saying she hated math and the end of kindergarten last year. I worked with her over the summer and took a different approach from the procedure drills that the school seemed to emphasize (i.e Math Minutes). Instead we worked on critical thinking and problem solving. She went from "I hate Math" to "more Math!"
This year in first grade she has Everyday Math. The approach is fine but the level isn't right for her. They've started math groups with another teacher but the first homework came home and "drill and kill" is a good description. It was 63 problems of 2 digit addition with regrouping. We managed to break it into smaller chunks to get through it but I fear the "I hate math" attitude will come back with a vengeance.
