how to help my twin boys aged 71/2 to understand math concept?

Question

They are unable to make out that 5 >3 in short they are unable to make out the greater number and lesser nos.Right now they are in grade 2 which is affecting them to do the sums like addition and substraction. They can do the addition without carrying but they forget to add the carry on which i have remind them all the time. In substraction they are well in without borrowing but with borrowing they cannot make out which one is greater and which one is lesser. they borrow even it is bot needed. that is the main problem. and only mean that they are unable to understand the number concept. I have tried with several method but in vain. pl help me to make tham understand the number concept.

Answer 1

some take a little longer to come to grips with math.not to worr.persevere and they should be all right

Answer 2

Hi:

Try the following things, a Chinese abacus, money (a lot of Pennies about 1,000 will do , ) and thirty small paper cut in into squares and numbered each a number 0 to 9 , have him count the number of pennies out and teach him to use the abacus. by showing him at for each penny he counts, he move one bead for it and add the correct number sheet of paper for it { like when one bead is moved then put a paper sheet label one, when he count 2 for the secound penny. Move the bead it the first column and put 2 there, when the third penny is counted then put a paper square label 3. so on unitil he reach the fifth bead { or the number five and put a paper square labeled " 5" }; he bring one bead from the top row down and put all the beads on the bottom row down and keep doing the bottom beads and replace the paper squares with the correct labels until he reaches the tenth beads { or number ten} then bring down the last top bead and push it all up to the top in the first column and put a sheet labeled "0" there , and then add the first bead in the second column and add a sheet label "1" and continue the continue counting and changing the label sheet in the unit column { or first row. }
until 10 beads have been count and move the bead in the second column and change the label paper in the second column to one label two and say twenty . and put a zero in the first row again. After a while he will learn the math concept on the counting concept as well as the placeholder and zero role in that . The pennies will visiable show him what the number is on the abacus and the number on top will show him that for every bead he moves it change the numbers to a diffrent value and it make it easlier to learn addiction and subtraction

Hope this helps

Answer 3

Use manipulatives. In particular base 10 blocks.

1. Show them how to do the addition and subtraction with the blocks
2. When they understand (1) show them the proper way to write down what they are doing. This is where you should point out how they are borrowing when doing the standard writing way
3. Wean them off

With base 10 blocks or other manipulatives they can easily see which is greater 5 or 3.

A final suggestion. Yahoo answers is not the best place to be. Or i would suggest the education section. There are many math illiterate people here trying to answer questions.

Answer 4

First off, remember that it has only been five years since their brains "began" developing the ability to permanently store data. Their brains only reached full size a year ago. They don't "begin" developing conceptual thought process until puberty. There a good study done by the University of Michigan titled the Amazing Life of the Human Brain. But, in all this, one thing you should note that that over the last 100-years, the average life span for humans has been steadily increasing, with development at the beginning of life getting slower.

Your children may be one of the newer humans whose development is slower and as a result, their life spans will be much longer. If the trend continues as it has in the last century, they are likely to live for 150 years.

Be patient, young males do catch on to math quickly, as soon as their brains are ready for it. Also, even when they do begin, it will not mean they understand the why something adds up a certain way. Right now they are just data processor, the why comes after puberty.

When they do, might I also suggest encouraging them to learn foreign language. Remember, computer language is a math based foreign language.

Answer 5

Physical objects always help in greater than/lesser than.
As for carrying and borrowing, perhaps they actually need to understand how to count with place value a bit better. Make sure to practice counting--emphasize that a 4 in the 10's place means 40, and not 4. You might do this with pennies, having them compare the 4 groups of 10 to 4 pennies. Make sure they understand that the group size goes up tenfold with every step in place.

Answer 6

first teach then the objects concept
then the best way to understand that is the number line. draw them a number line and show them with pictures of dots under each no corresponding to the value of the number
practice is the best way to inprove at math when i was a kid i was a little weak in math and my dad used to make me practice a lot and now im great at math

Answer 7

I used to use objects to help my kids count, I would tell them, put 3 in one hand and carry the other 2 into the other hand, it's hard for them but try to keep calm and they will get the idea.

Answer 8

nicely i'm 16 and performance absolutely understood my mothers and fathers dated in the previous, for a at the same time as. i do not keep in recommendations ever wondering about it at the same time as i replaced into 11, yet tbh i do not keep in recommendations a lot about being 11 (lol undesirable memory) besides the undeniable fact that i'd not imagine it can disillusioned me in any respect. yet, my mothers and fathers did get divorced at the same time as i replaced into about 11 and so that they dat persons now. i do not recognize if that makes a huge difference. in my opinion i could say they were all previous adequate to appreciate...x

Answer 9

Use physical objects.

Answer 10

they will understand that sooon, so dont worry, im like that, when i was a kid, im like that, but now, im good at math especially at algebra.
