Maths methods

I have posted before about my 4 year old - he's just gone into reception and he is working quite a bit ahead in number work. Anyway, he's enjoying doing more and more at home (he's v interested in it - we are not forcing him!) and I just want to check we are showing him the 'right' way.

He now knows his 9 times tables and 11 times tables up to 10 (I only had to tell him the 'rule' once and he got them both). Is that the way they learn them now though or is there a way I 'should' be showing him?
Same with adding two digit numbers - eg 46 plus 53 or anything like that - we have shown him the hundreds tens and units method that we used in school. He can now add together any two digit numbers if he has a pen and paper. But is this the correct way?

He is always wanting to do stuff like this and constantly amazes us with his aptitude for number work, but I want to tread carefully as I don't want to hinder his progress at school!
Thank you smile

Also any hints on the best way of learning the 3 and 4 times tables (he can do the 5, 2 and 10 ones) as he is asking me for his squeebles game!

For addition and subtraction, schools now use partitioning, which is splitting the number into tens and units. eg
43+56=
40 +3+50+6=
40+50+3+6=
90+9=99
They also use number lines and number squares. Hopefully someone will turn up who is better at the internet than me and can give some good links to explain it.

TBH it did not seem to confuse dd teaching different ways of adding

Four times table I think is done initially as doubling the two times table.

I found that getting a KS1 book from WHS helpful.

Thanks - that makes sense re the 4 times table! That does look like he will find that method of adding the 2 digit numbers ok too. I feel quite out of touch as I was never a maths whizz anyway!
