These things from our childhood - what on earth were they called?

[Circumferences]

Ok
Do you remember getting a square of paper, folding it into 8ths(?) Folding it back into itself to make a device you can hold and flick it back and forth.
You'd ask your friend to choose a number from the top, then you'd flip the thing that amount of times, and you end up getting an instruction or something at the end.

I'm "teaching" (it's just an after school club as a volunteer don't worry nothing official) some children how to make these in the club, but can't find anything online to help out with ideas as I've no idea of the search term !!

We live in the north west, child of the 80's

Fortune tellers here too.

DD has recently had pre-made books of them from Smiggle and Flamingo Paperie and they're called chatterboxes on both of those.

We definitely didn't call them that but I can't remember what name we used.

Chatterboxes - I work in a school and am often asked to make them.

All skipping is banned in dd's school. Apparently they don't have enough staff to monitor it properly.

That's awful. No wonder children are becoming obese. I am a retired teacher and we had a box of ropes to take out at playtime. Two people on duty and I'm not aware of any dreadful injuries. You just had to stop them playing 'horsey' (rope round neck) or twirling the wooden ends round.

We called them a flick-flack 🤷🏻‍♀️

In the NW of England in the 1960s we called them 'snap dragons'.

Kids make them them themselves.
A times table question on the outside and answers inside. Challenge each other.

Fortune tellers! We used to make them in school in the 70s with the names of the popular boys inside and the result was who you would marry.

I'm 58

We called them chatterboxes in my dim and distant childhood!
