Mnemonic devices

Let's share. Mine are mostly the golden oldies for math. I'm hoping to see some better ones from you guys!!

Trig: SohCahToa
or Oliver Had Another Handful of Apples

--- Co-Co=No No (Trig-- cosine and cosecant, sine and cosine are NOT recipricals)


---CAST (start from Quadrant 4, counterclockwise, for what's positive where
or All Students Take Calculus (same rule, starting from Q I)

Order of Operations:
-- PEMDAS (parentheses, exponents, mult, division, add & subtract)

or-- Please Excuse My Dear Aunt Sally (same rule)

Metrics: Children Hate Doctors; Usually Doctors Charge Money
(I just got that one from my friend who teaches Chemistry; the "U" is for basic unit, such as meter)

What else do you have?

I am going to be a clarnet stealer... because those are the first that entered my mind.

I know the geography one!! George Elliott's Old Grandmother Rode A Pig Home Yesterday. I even teach that one.

For planets, I have used My Very Excellent Mother Just Served Us Nine Pizzas.

Cardinal Directions-
Never eat soggy worms.
Never eat shredded wheat.

There's a whacko one I came up with right before a spelling test last year, but I don't remember it. Something about the h eater, yet the word wasn't heater. Whatever.

The one I teach for metric units is King Henry Died Unexpectedly Drinking Chocolate Milk. (Unexpectedly is Unit.)

For the levels of classification of life forms (that would be Kingdom, Phylum, Class, Order, Family, Genus, Species): in the elementary classroom, it would be King Philip Came Over For Good Spaghetti; for those taking teacher tests, it's more vivid if the last word is Sex.

There are few of us who still remember the WHOLE rhyme for the numbers of days in the months, but, geek that I am, I do:
Thirty days hath September,
April, June, and November.
All the rest have thirty-one
Save February, which alone
Has twenty-eight - except the time
When Leap Year makes it twenty-nine.
And then there's the truly dumb but useful way to remember what 7 times 8 is: 56 = 7 * 8. That is: five, six, seven, eight.

Alice, how does CAST work?

The way I remember the quadrants is to number them with Roman numerals, and then the quadrants that have just one Roman numeral I (that is, I and IV) are the quadrants in which x is positive.

By the way, it's mnemonic. With, I suppose you could say, a silent m. Two ways to remember that m at the beginning: (1) mnemonic and memory both begin with m; (2) amnesia is a-mnesia is literally 'not remembering'.
