abacus ansan

[Chris1]

Hi 2010BEBES,
You can buy an abacus here-     http://www.soroban.com/english/shopping/

The Pacchi starter abacus uses the same colours as our Abacus Flashcards and covers numbers 1-999.

Thanks a lot Chris,

I can see that he is uncomfortable and do not understand how he can do all those additions just imaging the abacus. It's incredible. I will try to look more about it.
Upt o what age will the Pacchi be used. I think is is too small (3 digit number?)
Maybe the plastic Soroban is better.?

Would you say the color ones (like the flash cards) are better. Wouldn't the colors distract him?
Thanks for the link.

2010BEBES,
I would recommend starting with the smaller abacus which can represent numbers to 999 and introduce the larger version later.  The colours separate the hundreds, tens and units.
I have just added the following to our files

+2 Abacus   1,3,5...19                                           +2 Abacus 2,4,6...20
+2 Abacus   19,21,23...39                                      +2 Abacus 20,22,24...40
+2 Abacus   39,41,43...59                                      +2 Abacus 40,42,46...60
+2 Abacus  59,61,63...79                                       +2 Abacus 60,62,64...80
+2 Abacus  79,81,83...99                                       +2 Abacus 80,82,84...100

Status is currently unapproved.

Hi 2010BEBES

I forgot to answer your question about when to introduce an actual abacus.

The truncated Pacchi soroban is intended for children aged around 3-5 years old. It only has three bars because it is designed for young children, with the beads in the first column (that denotes ones) having a first colour, the beads in the second column (that denotes tens) having a second colour, and the beads in the third column (that denotes hundreds) having a third colour.

The colours used on our abacus Flash Cards fortunately match the colours used on this starter abacus.

Tomoe Soroban Co.,Ltd also sell abacus Flash Cards    http://www.soroban.com/english/shopping/

Hi Chris,

Do you think with just the flashcards we can teach anzan, or would it be necessary to have the actual abacus?

Thanks,

Shen-Li.

Thanks a lot Chris1
I am looking into one of thes options.
1) get the Pacchi from Tomoe Soroban. I already contact to see if it can be ship to Peru.
2) get tha amazon (not so color but half the price and with more digits will last more). I am afraid the reviews about the FREE learning computer classes did not work. Maybe I'll need a book

Do you or someone has any of these products?
And what about a book to show how to teach kids?
One seems too simple, other too expensive, Do you think we will need it?
How about:
http://www.amazon.com/CHINESE-ABACUS-step-step-multiplication/dp/184799864X/ref=pd_sbs_t_2#_

It has good reviews.

Hi ShenLi,

I don’t know the answer to your question.  It might be possible to teach addition and subtraction with the cards. It would be a little more challenging to teach multiplication because the algorithms are more complicated.
The cards are a good introduction to the visual patterns.

Hi 2010BEBES,

Your link took me to the Chinese Abacus which is not the same as the Soroban Abacus. China has it's own version of the abacus, a 2:5 bead suan pan.

See MathAbacus.com and go to free downloads for sample pages. The e-book package is the cheapest option.

A free abacus instruction manual is available here-http://webhome.idirect.com/~totton/abacus/pages.htm#Soroban1

Thanks Chris. Karma.  I'll start with the cards and see how we go from there.  Probably try ordering the Pacchi abacus...

Dear chris,
         Where can i get the flashcards software system that flashed the number on the computer like anzan students are doing, they can enter the number of digits and rows they want to practice. It is good, my kid is learning abacus but don't have the flash number software.. can you help me? i'm from malaysia.

Thanks chris so much for the link

I like it for practice. Nowadays at the age of computers less and less calculations are done, worst of all mentally.
This is very goog. I tried 10 numbers of 1 digit and had to make some effort. I think i am a little rusty.   

Extra practice will be ok.
