My year 1 #primaryschool #classphoto from 1965.
The school told my parents I should be 6, but they were determined I start my schooling at 5 years of age & my father wore his police uniform - so… all through my schooling I was the youngest in my class.
34 pupils in my class, which was the norm until #highschool when class sizes dropped to mid 20’s.

Children learn in school to test numbers for their primeness by trying all sorts of possible divisors, starting with two and then going up.
Shouldn't it be enough to try divisors that are prime, and only those, whose square is smaller than the number to test? Like, e.g., for any number smaller than 121 (11²), shouldn't it be sufficient to try whether it's dividable by 2, 3, 5, or 7? Am I missing anything?

I created these illustrations as timers that teachers can use in primary school, and they’re also great for use at home!
