The area of a quarter is Pi / 4 x r^2 >>>>. The White square is a height of triangle base thing so r^2 /2 as we know the hypotenuse=r >>>>> Hence the area of the curved areas is [(Pi / 4 x r^2) - (r^2 /2)] x 2 = A1 >>>> The small shaded square (A2) is kno...

as he hasn't learnt pythagoras' theorem, I've used the "area of biggest square in a circle" (2Γr^2) to explain to him

We just use that the area of a circle of radius $R$ is $\pi R^2$, hence the area of each quadrant is $\pi 8^2 / 4=16 \pi$. Also, by Pythagoras' theorem, the diagonal of a square is $\sqrt{2}$ times its side (where \sqrt indicates the square root function)...

and I'll be very happy if he does become a Patek collector, since this will mean he has some accomplishments in his life π

I know now whom to turn to if I ever end up having children in need of math tutoring! xD Somehow, despite having two parents who were both either excellent or brilliant at math, I utterly 'suck' at it LoL ........

...kids that age in the US would never get that question until late in high school if ever : )

all 12 year olds here will take one of the most important national exams in their lives after which they'll find themselves being "categorized" according to their results

...we do not have here. Rather students can take SAT tests that can affect their college choices...

They were debating removing the SAT testing requirements altogether........

In the US and Canada, later on the (undergrad) college students can also take the Putnam Exam, an equally optional and fun but *horrendously* challenging competition for talented students, which essentially ranks them at the country level before they can ...

and yes, his school makes their students take part in math olympiad every year and offers extra classes for that. my son has never made it to the next round though π
i prefer to let him enjoy his childhood as much as possible with the right balance. it's ...

That's also a critical age for children to develop self-confidence, a correct way to relate to the other kids of both genders, etc...success in my view should always be pleasant and never toxic! As a future HUGE Patek collector, your son should first and ...

Where's that Patek Philippe advertisement of a dad and son doing the son's homework together? ...

Or his math homework (it looks like math) in this photo isn't as difficult as your child's homework!

for a decade, and I oversaw the production of K-6 lessons in English and Spanish, print and electronic formats, books for students, teachers and parents. I retired 10 years ago and couldn't solve that problem now without thinking hard and doing some diagr...

My expertise lies in getting the books out on time without errors, not with coaching students on how to do math. Anyway I am retired now... but thank you for the offer.
