I am new too, so take this with a grain of salt. I just went through a situation that sounds like yours for my dd7. After bringing the reading mat that she has enjoyed from home. The teachers informed me that they would feel ucomfortable skipping to that point. They needed to make sure that dd7 could handle the change. They informed me she could bring her own reading mat to school anytime however the teacher still had to make sure dd7 new every step of reading.
Be strong and get under their skin a nice way. When you ask people for help they want to help. Take the first step for change, be willing to stay after or before school and read with your dd when teacher is present in the room. You dd might love having you there. If you assist the teacher in doing her job she will probably come around. Mean while speak to Admin. of school ask for their help for you and the teacher.
Good luck!
