I saw this with my husband, we are expecting our first child at the end of june I loved the experiment with the dolls Thanks for posting the link!

barbapapa

You can buy Barbapapa on amazon.fr but you will need a dvd player that can play all region dvds, since this is obviously a europe-region dvd

I have all the GD books, if you don't want to buy them all I'd recommend (in this order)

-How smart is your baby
-Physical excellence book
-multiply your babies intelligence

I think this way you get the most complete explanation without buying every book

I am a potential customer in the future and use slackware linux

I think it's so funny that as adults we see this as strange when in fact they are quite smart to assume b and d are interchangeable in a way.

Take an elephant for example (that is, envision it in your mind, I'm sure the zoo would mind if you just took one).

Have the elephant face to the right.

What is it? An elephant.

Have the elephant face to the left.

What is it? Still an elephant.

Have it do a handstand! (Again this is an elephant in your mind and those can do handstands! True fact!)

What is it? STILL an elephant.

So it's kinda logical that b and d are the same, and could even be p or q, because honestly, it's just the same letter facing different ways.

Children are smart and know that an elephant keeps being an elephant no matter which way he faces, now it' sto us to teach them that with letters this is not the case

I cannot answer your first 2 questions since I do not have the math book.

Your third question I can answer. It is impossible to do all possible equations. In the Doman Math system you are not teaching your baby to memorise every single possible equation in the world. You are teaching your baby what + means and what = means. Through the dot cards you have already thought him the quantities and the words that go with it. Now you show in what ways you can combine quantities.

Just like when you talk to your baby, you might never say "There is a pink elephant in my soup", but because you said sentences like "This is a pink blouse" "There is a fly in my soup" "This is a blue elephant" your child is able to combine these buildings block in different ways.

So if your child really knows how much 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 are and then you teach him that 2 + 1 = 3 that 4 + 1 = 5, he should (obviously after a longer while and more added facts) realise that 7 + 1 = 8

I hope this helps
