edit: thanks for pointing out that I misread which type of pressure is being applied.
What is taught in 4th-5th grade math? Fractions? Decimals? Multiplication and division of larger numbers (maybe the accursed "Long Division")?
These are not exactly the most exciting or interesting things to learn... If I was a parent of this child, I'd take it as a notice that they are falling behind, probably from lousy teaching and parenting. It's not going to get any better by ignoring the problem. They've got another 8+ years of school to go, they aren't even halfway done. You need to show them why they can find it interesting, the same way you would show a student who really loves math why reading/writing is important. Or why history matters... If you just assume a 10 year old can fully decide what their adult self likes/doesn't like and what they need to know, then you are failing as a parent.
I ask because I remember saying stuff like this before I had kids. I don't anymore. I've tried to learn not to judge others parenting but hey that's just me.
No one, at least that I've seen. Is saying men don't like babies and animals too. There is nothing wrong with that. To assume that you have to like something based on your gender is ignorant.
To assume that you can't like what is "stereotypical" liked by your gender is equally ignorant.
People have a massive amount of fluctuation in what they like and don't like, part of being a parent is about recognizing the individual that your kid is and not pressing what YOU want on them, but balancing that with what's best for them based on what you know that they don't.
I also know that as a parent, you're always failing. You just do your best to fail as little as possible.
