State primary in the 70s, and we were all chanting all tables to 12x12 by rote, in what is now Y2/P3.
I personally think that rote learning of tables makes progressing in primary maths much easier, and my own anecdotal experience of those 70s schooldays was that it was very achievable for the majority.
My daughter’s school push them in Y4, and speaking to parent friends and teacher friends, they find it achievable.
My Y6 is doing SATS prep currently. There is a Maths Reasoning question that has as one of its steps “12 x 12”. The far more important knowledge (in my opinion!) is:
- what is a perimeter
- all sides of a square are equal
- the area of a square is L x W (that was the 12x12 bit!)
My daughter and I discussed how much more time she has, because she doesn’t needs to write out a 12 x 12 multiplication, go 2 x 2 = 4, 2 x 10 = 20. Total 24. Remember to put a zero in the unit column. 10 x 12 is 120. 120 + 24 is 144. So many steps, so many chances to make an error. Instead, she just instantly knows the answer is 144.
It frees up so much time (and gives confidence!) to concentrate on new ideas in maths.
I’m not saying that your daughter wouldn’t catch up - as you say, you didn’t know them. But I would say, as I’m in the thick of Y6!, that strong times table knowledge in Y4 pays dividends in Y5, and is essential for SATs in Y6. And, looking ahead to Y7 - at least what MyMaths set at my primary tells us is Y7! - they really help there too.
For most children I’ve been in contact with through my own children, I would say YANBU, it isn’t too much for end of Y4 to know all your times tables and division facts. But it does take a decision to focus on it!
