This always gets a big laugh when I do a Singapore Math Teacher Training:
Student's Misguide to Problem Solving
Rule 1: If at all possible, avoid reading the problem. Reading the problem only consumes time and causes confusion.
Rule 2: Extract the numbers from the problem in the order they appear. Be on the watch for numbers written in words.
Rule 3: If rule 2 yields three or more numbers, the best bet is adding them together.
Rule 4: If there are only 2 numbers which are approximately the same size, then subtraction should give the best results.
Rule 5: If there are only two numbers and one is much smaller than the other, then divide if it goes evenly -- otherwise multiply.
Rule 6: If the problem seems like it calls for a formula, pick a formula that has enough letters to use all the numbers given in the problem.
Rule 7: If rules 1-6 don't seem to work, make one last desperate attempt. Take the set of numbers found by rule 2 and perform about two pages of random operations using these numbers. You should circle about five or six answers on each page just in case one of them happens to be the answer.
You might get some partial credit for trying hard.
Credit goes to Lynn Nordstrom for this piece. I've received it a couple of times in my email over the years. If anyone knows the source, I'm happy to credit them!
I love it!

I don't know if you were around back when C. was in 5th grade and we had him memorize and rehearse a stock short answer for the state test: "I looked for a pattern and then I guessed and checked."
