Happy update. Dd was running late to school today so dh did not have time to talk to teacher. I picked her up and mentioned to the teacher that we have reviewed her report and wanted to share some stuff with her via email or in a meeting. She immediately asked me if I wanted to meet her now, in 10 minutes after the last student had been picked up. I wasn't prepared for this but happily obliged. I came right out and told her that we think dd is hiding her abilities at school. I gave her a brief overview of what dd is doing at home on her own. The teacher was surprised and she held my dd's hand and said I only know her for two months so I haven't had much time to know what she knows. Then she turned to my dd and said, you don't need to feel afraid to tell me what you know. That way I can give you more interesting work. You don't want to come to school and be bored, right. Then she went on to explain to me how she can differentiate for dd. I did tell her that since we haven't formally taught or tested dd, we don't know what gaps she may have. Teacher assured us that she would give dd some practice work to ensure the basics are well covered. Overall it was very positive friendly meeting. I am thinking of sending a follow up thank you note. Thanks again to everyone here for their wonderful support and advice.
