my son is almost 2 years old now. He can recognize quantities up to 5 and counts to 20. Do I have to start to show equations now? or is it too early? The reason why I am hesitating is whenever i try to show an equation he starts to count or tell how much exactly it is. or is it ok even if he do this? In the Doman book it says to wait till the child understands quantities upto 10.
Can anybody suggest something.
fazy,
I would suggest you start with equations. I do 9 equations a day, but split them in the sessions. That is the only way my daughter keeps her attention. I also would suggest that you keep teaching you son the rest of the numbers up to 100. Have you read Doman’s both “How to teach you baby math” or have you read some of the posts here about teaching math?
Hope this helps!
