Hi
this is for TheRoundTable:
I've just checked on my parent dashboard on Mathsfactor for DD1 - there are 69 homeworks for multiplication. So about 14 weeks (at 5 lessons per week). Now that is a long time but lets review what that covers:
1st a DC has a practice - say with x2 in order going forward to x 12 and then back down to x1.
2nd a DC has a practice or two where it's mixed - so sometimes 6 x 2 and sometimes 2 x 6, but in order.
3rd a DC has a few practices where it's all mixed up - so 1 x 2, 10 x 2, 12 x 2, 2 x 2, etc...
Then a DC adds the next times table.
Once you have a family (so x2, x4, x8 or x3, x6, x9) there's some practice with them all mixed.
4 x 12 = 48 (48 practices on each times table)
4 x 2 = 8 (8 practices reviewing times table families - 2/4/8 adn 3/6/9)
There's some extra review for the tricky ones you just have to know - like x7
There's then some review with all the times tables mixed up together.
So that makes 68 + the Grand Genius text 69.
Aside from this there are games available on the mathsfacctor arithmetic school that also help revue multiplication facts.
I'd say that at the end of that 14 week multiplication unit my DD1 had the idea, but when she started division (inverse multiplication) that's when she really bedded down her times tables. By the end of that session she knew it.
Yes, times tables go on and on and on. But I'd say once a week or so, you're moving on to another times table or reviewing a family (2/4/8 or 3/6/9 or the whole of x1 - x12).
It was about 5-6 months of work before this multiplication unit in the arithmetic school was complete - and yes it did drag a bit - but the point was the learning was rock solid and helps so much now DD1 has gone on to do work with fractions/ decimals and percentages.
Everyone's circumstance is different of course but at our school 1/4 to 1/3 of Y6 students are still learning their times tables upon going up to Senior School and have no division (inverse multiplication, let alone division with remainders). x11 and x12 tables are not taught at our school, which isn't the end of the world, but I'm not really clear why not.
I'm definitely considered a PITA, but I personally wasn't happy for my DDs to leave primary unable to multiply let alone divide. So, at least from our perspective this seemed a speedy, successful and logical approach to teaching/ reinforcing learning of times tables/ inverse division facts.
