math facts
Mathematics is the academic discipline, and its supporting body of knowledge, that involves the study of such concepts as quantity, structure, space and change. The mathematician Benjamin Peirce called it "the science that draws necessary conclusions".[2] Other practitioners of mathematics maintain that mathematics is the science of pattern, and that mathematicians seek out patterns whether found in numbers, space, science, computers, imaginary abstractions, or elsewhere.[3][4] Mathematicians explore such concepts, aiming to formulate new conjectures and establish their truth by rigorous deduction from appropriately chosen axioms and definitions.[5]....

100% Q: What exactly are "Math Facts?" and how do I teach them to my son?
I have been told he needs help with his MATH FACTS. I want to help but don't remember that from school and just want ideas / tips from others (rather than soley the teacher) on what works or has worked for your child. Thanks!
A:Math facts are the basic operations of math, like addition, subtraction, and multiplication and division for slightly older kids. If he needs help with math facts, that probably means that he needs help learning to do operations quicker and more efficiently, ie: not having to count on fingers, etc.
To teach them to your son, a lot of practice is the best way. Addition and subtraction are taught well with objects, and multiplication and division operations can be memorized.

100% Q: Good sites for learning multiplication and math facts for kids with learning disabilities..?
I have a 13 year old with some severe learning disabilities and a processing disorder. Math facts are extremely tough..they slip away no matter how often we go over them. I have tried using music, rhymes, pattern cues, reptitive drills. I am at a stand still. I have continued to let her work on math lessons...learning basic algebra, more complex math, fractions, etc...but she still needs to use either a math chart, her fingers or written marks to do the answers and it is frustrating. Any ideas or suggestions...especially for websites, books or computer programs...would be most appreciated.
A:Finger math is one good way, and no memorization is required. These sites will show you a few strategies for figuring out various ones. Use as many of these tricks that will work. If she becomes adept with some of the finger math tricks, there is really no need for her to use her energy on memorization. Then try this - it is a method I used with my classes and it seemed to make quite a difference.
I would write all the lists of the times tables on the chalkboard from 0 x's to 9 x's or 12 x's, whichever was needed. Then I would say, "Which ones are you sure you know?" Most of the kids knew all the 0 x's, and all the 1 x's and all the 2 x's and all the 5 x's, so we would erase all of those. Remember that you have to erase them all in two places, because 0 x 5 is the same as 5 x 0, etc. Then we would look at all the ones that were left, and I would point out that each one is there twice, since 7 x 8 is the same as 8 x 7, so then we would erase one of every pair. What was left was what they had to focus on memorizing, so it made the task seem much less insurmountable than it did before. With kids with learning disabilities, making the task seem possible if sometimes half the battle.
I hope this made sense to you. Best of luck with it.

100% Q: How can I help my son remember his math facts and spelling words?
Spelling words he remembers them long enough to ace the test, but ask him 2 weeks later how to spell them and he probably can't remember more than half of them. He is learning multiplication facts right now, and he's having a really hard time learning them. Just doing flash cards takes a considerable amount of time, because he has to stop and count up, so he's not doing so well on the timed tests at school. If anyone has any hints on how to help him I would really appreciate it. Thanks!
A:Teach him to use Mnemonic devices. A mnemonic (pronounced [n??m?n?k] in Received Pronunciation) is a memory aid, and must serve an educational purpose. Mnemonics are often verbal, something such as a very short poem or word (which may be made up), particularly lists.
Mnemonics rely not only on repetition to remember facts, but also on associations between easy-to-remember information and to be remembered lists of data, based on the principle that the human mind much more easily remembers data attached to spatial, personal, or otherwise meaningful information than that occurring in meaningless sequences.
The sequences must have some connection to a person's existing semantic associations; if a random mnemonic is made up, it is not necessarily a memory aid.
The word mnemonic is derived from the Ancient Greek word ?????????? mnemonikos ("of memory") and is related to Mnemosyne ("remembrance"), the name of the Mother of the Muses in Greek mythology. Both of these words refer back to ????? mnema ("remembrance").[1] The first known reference to mnemonics is the method of loci described in Cicero's De Oratore.
Since your son is young, use things he likes or enjoys to help him to remember his schoolwork. Example: Cartoons, video games, certain shows he may like. The reason he can't remember things he aced on a test is because he studied those items and put them in short term memory and once he finished using them his brain disregarded the material learned like trash, so there for when he was called to recant what he aced on a quiz only a couple of weeks earlier, his brain could give him nothing because that slot was already wiped clean.
A boy (aged 8) said he was dumb and could not understand things in his math class, but when this same boy got in front of a video game he played it very well, I mean he knew how much time he had before he had to jump, he knew he had to get extra men so he would not die (in the video game), and he knew the more points he racked up the higher his name would be on the "high scorers list".
Now, this boy demonstrated certain skills that he previously stated he never had. Case in point , the amount of time he needed to stay and leap off of a given target, he calculated in his mind, getting more men in order to stay in the game, he reasoned and figured out that it would be to his benefit to get more men; showing he had the brain capacity to reason, calculate, and do what he needed to do to win.
In the same way, your son could use those skills but with the help of mnemonic devices to aide his education.
Hope this helps

100% Q: What are the pros and cons of using timed math tests to support memorization of math facts?
I am trying to research the benefits and/or hindrances of using timed math tests with my 3rd graders. It seems to improve scores for most, but is a frustration for others. What supported research have you seen? Personal experiences? What is your opinion?
A:In my district, I think they have done away with timed test for multiplication facts and instead have used conceptual math to teach the facts, so students understand the process. Although many students have not memorized the facts, they have several avenues for arriving at the right answer, and they do better at math overall-- especially in the secondary level-- due to practicing the logic skills. At least, this has been my experience.
I believe they have done away with timed tests (drills) primarily because it is impossible to modify such a test for students with special needs. Imagine a student who is having trouble writing or reading numbers (dysgraphia, dyslexia) trying to complete a timed math test.
And what about memorization? Do students who have memorized math facts really understand the logic behind the facts? Do they understand the relationships between multiplication and division/addition and subtraction AND between addition/multiplication and division and subtraction? The real litmus test would be to evaluate their mastery over the operations at the higher levels (for instance, learning long division, after learning the multiplication and division facts).
It would seem that a student who understands division in a more conceptual way, is likely to master long division more quickly or easily than the student who simply memorized the facts. The student who has not memorized the facts is more likely to make mistakes with the math facts. However, that same student would also recover those mistakes using the techniques he/she learned to comprehend the facts in the first place.
Personally, I was taught by rote memorization and timed tests in my youth, and I know the math facts by heart. I applied the same techniques on my own by high school, memorizing common exponents, factoring of polynomials, and square roots/cubed roots. However, those timed tests were daunting.
Teachers may use timed quizzes for practice these days, but they are not graded as examinations. These are given for credit or a homework grade (maybe 5 pts., for effort).
Obvious benefit: less mistakes in computation
Disadvantage: Unfair practices that hinder students with special learning needs.

100% Q: MATH facts?
do you ANY three digit number say 100x+10y+z if made a six digit no. by writing the number again in its front i.e.
100000x+10000y+1000z+100x+10x+y is always divisible by the three digit no. itself and also 7, 11, and 13!!!
And similarly any such four digit no., if made an eight digit no. in the same way is also divisible by the four digit no. itself as well as by 73 and 137!!!
most no.s when multiplied by 11 have reversed digits of the product of the same no. reversed and 11:
i mean for example:
13 x 11 = 143
but 31 x 11 = 341...
1729 is the smallest no. or maybe the only no. that can be expressed as the sum of two cubes in two completely different ways:
12^3 + 1^3 = 1729
10^ + 9^3 = 1729
A:Yes, they are math facts.
