I have used them in the past and I find most of them to be very catchy! Take for instance the one featured below:
|Dad's Silly Triangle|
This mnemonic helps you to remember the relationship between Speed, Time and Distance. Dad has a silly triangle! Hmm! Can you see that silly triangle?
If you need to find D, cover up D in the triangle and you get S × T.
If you need to find S, cover up S in the triangle and you get D / T.
If you need to find T, cover up T in the triangle and you get D / S.
Isn't that amazingly more simple to remember than the formula?
There are lots more!!
