My maths one is this for circles -
Hey ho diddly dee,
The ring round the moon is pi times d,
But if the hole you want repaired,
The formula is pi r squared

Smiles Of Happiness, Come After Having, Tankards Of Ale

(Although would have no actual clue of how to use them)

I can never remember any of these, I think it's to do with my dyslexia. it seems to make it all the more confusing.

Repetition and frequent use is the only way for me to remember, dates, planets, History, spelling etc.

Never Eat Shredded Wheat, is the only one that has ever stuck.

I can't think of any others offhand except
In 1492, Columbus sailed the ocean blue.

I once had a student claim it was

In 1493, Columbus sailed the deep blue sea.*

Merry Prefer Blue Peanuts (carbon atoms in organic compounds)

it is necessary to have 1 collar and 2 socks.

Tableclothing yep that is the sort of thing that would happen to me, my brain would remember it as sea and not ocean then stick the blue were it would fit with sea, so then would fine the number that rhymed with sea.

Merry Prefer Blue Peanuts (carbon atoms in organic compounds)

I'm a PhD chemist and now I'm baffled wondering what the heck that's a mnemonic for.

Hey diddle diddle
The median's the middle
You add and divide for the mean
The mode is the one that you see the most

Richard of York gave battle in vain (rainbows)

Mrs Nerg - was that one something to do with photosynthesis??

The Orange Alligator Sat On His Cornflakes And Hiccoughed

Poor Johnny Brown is dead and gone
Alas, he is no more
For what he thought was H2O
Was H2SO4

@ErrolTheDragon, my last dabble with organic chemistry was in 1989, so I might have got what that mnemonic is about wrong. But - it stands for Methane Propane Butane Pentane. I am happy to accept that it’s rubbish though, and that I have spent the last 31 years cluttering my brain with junk.

Please Keep Charlie's Monkeys And Zebras In Lead Cages Most Securely Guarded: the activity series in chemistry, with potassium being most reactive.

There are some geology ones for the time periods aren't there?

That pen is not much good - vowels in shorthand and where the outlines sit!

@Bridecilla I love that hey diddle one going to teach my son that!

I already taught him Richard of York one for the rainbow - can't believe he didn't know it from school and didn't know the orders of colours of the rainbow!

My one for necessary is "1 Collar, 2 Sleeves"

Also remember "Every Good Boy Deserves Football" and "FACE" for music

Silly Old Horses Chase A Herring To Outer Alaska: trigonometry, also known as SOHCAHTOA

Isn't SOHCAHTOA easy enough to remember by just saying SOHCAHTOA?

@Aria20 there's a short youtube video of a guy singing it. I play it to annoy my students. Really makes it stick in your head though!

Snitches get Stitches?

“Michael Vinton eats many juicy spuds until nearly puking.”
The order of planets from the Sun. Does anybody else know it? I think it’s a family made up one.

Nonsensical but it’s never failed me 😁
