Our DD crawled into my lap and was very disengaged when we went to an info night for her gifted fifth grade. It had me very worried but she was tired and a bit sick and in a bad headspace generally. She loved it. However, word searches wouldn't have excited her either, more so because of the competition element. Yep hope for a different teacher.
Sounds like you have a good current school with reasonable challenge and you are doing a good job. You are lucky your DH can provide some enrichment occasionally. If he is stimulated and learning in LA that's great. I wouldn't worry.
For the science and math....why not have a chat with the school and just ask what they think, if they have any suggestions.
