When’s the last time you did long division, and worked with a mathematical expression like this? I saw it and began thinking about square roots! “What in the hell is this?” I grumped, “common core math?”
Yes. Yes it is, Filthie, and you’re too retarded to do it!😡
If you don’t mind, maybe I’ll just borrow these and practice with ‘em a bit.
I used to practice with these flash cards. Frankly, it was the only way to learn multiplication and division (and addition, and subtraction). We did the tables zero through 9, and I should have learned zero through 20.ReplyDelete
I still have the sets mom-n-dad bought plus the ones where you fold a flap over a list of words and by changing the first letter or two you get different words. Very useful when teaching your own children basic math and reading.ReplyDelete
If only they still did stuff like this in the schools. Sometimes the old ways are the best ways.ReplyDelete
I learned basic math from flash cards such as these. If you need to do any rote memorization, they are great.ReplyDelete
We had to memorize about 50 or so fire control symbols when I was in "A" school in the USN. Me and a buddy used home made flash cards and quizzed each other until we had those symbols down. Took a couple of days but we both aced the test.
A simple marker and a stack of 3X5 cards can be used to make them. I did the same thing for my daughter when she was learning her multiplication and division. She became a math wiz.
When my granddaughter was in grade school, I had occasion to relearn long division. It took a while, but I noodled it out on my own. It is said that it only takes 10% of the time to relearn something as it does to learn it in the first place.ReplyDelete
