This is the technique I taught my two dearest daughters Angel and Riana in adding numbers quickly. My younger daughter
Riana Ysobel had their exams this morning, I reviewed her in Math and that is why I remember to share this EASY technique I have accidentally learned to you. I wanted
to ease your child’s “addition” too :)
The Technique
Explained:
Using both hands in adding two sets of numbers from digits 6 to 9 which the grade
schools, our children, find really really hard to sum-up.
I came-up with a technique, five fingers (5) from
each number added are folded therefore automatically reserving 10 as the final addend to easily add with the
remaining “standing” fingers. It is easier to add the leftovers, this is
helpful for kindergarten and elementary students.
The Tool:
Both hands' fingers alone J
Let us try this:
1. Let your child demonstrate "8" in her hands like this:
My six-year old's hands :) |
2. Ask her to fold 5 of her fingers and let the remaining fingers standing on her left hand. It must show 3 fingers left standing, leftovers.
folded five fingers, left hand |
3 leftovers left hand |
3. Ask her to show 7 in her fingers. Then ask her to fold 5 of it and let the remaining ones standing on her right hand, it must show 2 leftovers.
Seven |
Folded "5" from given addend "7" |
2 leftover from 7 (5 folded) |
4.
Then
ask her to count together both
of the leftovers from each hand. It shows 3 and
2, so its total is 5..plus the 10 (sum of two 5’s from each given addends she folded). Speak
of the sums five-ten, then tell her there is no five-ten in counting so the
answer is FIFTEEN.
Let your child count together the leftovers, that is "5". |
The folded "10", the sum of folded 5's from 8 and 7 |
My six-year old, modesty aside, just by looking using this technique she easily gets it is 15. I am telling her five-ten – there is no five-ten
–but fifteen. She knows it should be fifteen. The added trick is connecting the sums to the
right answer by using a rhyme.
Here is another example:
Like
when adding 7 and 7 = 14
Folding
from each given numbers, each digit will both have 2 leftovers of each –when
added results to 4. Having the folded , 10 is the total
of folded from each. Spoken together is four-ten sounds similar to FOURTEEN , the correct answer.
Let
each leftover be represented
by each (in the example above, 2 fingers standing from each) hand so she
can easily add or count it together or see the answer just by looking i.e. “4” and the “10” folded = four-ten (of course
that is wrong) but hearing that when she uttered it, she immediately connects
it to the right answer which should be fourteen (rhymes with four-ten, the sums). That is why I am asking my child to speak the
sum of the leftovers and the folded 10 fingers.
I hope you will soon learn about this and soon teach your
child how to do it. I hope too that more
kids (like my daughters) will be happy to add numbers from now on…
Please plus, like, share, tweet and ask others to see so
they too can help their kids in Math.
Have a great day everyone. Thanks
