I have read the first two pages and I am so angry, absolutely fuming at people who say you are unreasonable!
You might want to RTFT at the many people that explain clearly the difference between someone saying "so and so is a paedo" vs "so and so likes to look down my top". Blanket comment with no cause vs actual safeguarding concern.
As a mother we worry anyway, but if my daughter came and told me this I would never consider it gossip! She is only 11!
You honestly think 11 year old girls don't gossip?
11 year old boys defo do, it's been a long time since I was 11 but I seem to remember similar happening.

I would go and speak to the headteacher discreetly even if only to discuss whether they could speak to the girls and get to the bottom of it. I rather be safe then sorry. To everyone who thinks you're unreasonable for worrying, or calling your daughter speaking to you 'gossiping', they should be ashamed. Very very ashamed especially after the recent news of the nursery school paedophile Vanessa George's story!*
Why are you comparing 11 year olds saying "he's a paedo" with nothing behind the claim and a prolific paedophile who only got caught because the person she was sending images of babies to got caught? She worked in nurseries with babies. Not even remotely the same. My son was in Nursery in Plymouth at the time of her arrest.
I'm not ashamed for not taking seriously young preteens random claims seriously. My son said his HOY is a perv the other day - I asked why he thinks that and he said "he works in a school". 🙄 I've not spoken to the head about it yet.
The OP has said nothing beyond a random claim with nothing further. On the basis of that information I think the head would roll their eyes a little at getting forced to investigate a teacher employed with a DBS, references, etc etc etc.
Lots of people have talked about their school years. There were two teachers who ended up with students at my school. They are both still married to them starting the relationship in sixth form. It wasn't appropriate at all. LOTS has changed since I was at secondary school. The checks and balances are far far far more robust.
I've also known a male and female teacher
If the OP had said I'm concerned, my daughter is creeped out by this teacher, he keeps her friend in all the time, and looks at her funny could he be a danger I would have responded very differently.
