Hi Thoughtsplease:
Have just scanned the conversation but heartily agree with ineedaholidaynow - schools are now required to have pupils know times tables to x12 by end Y4 (earlier & more tables than previously) & many schools presume parents will break down and help with this at some point.
What you can do.
Learning 2/5/10 - is classic start - but double check she also understands x1 (anything x 1 is itself) and x0 (anything x 0 = 0).
With x2 - see if she understands the principle of doubling - because that will help with other times tables (x4 [double x2]/ x6 [double x3]/ x8 [double x4 or double x2 and double again]/ x12 [double x 6 or double x3 and double again])
x3 has to be learned - playing counting by 3 games or playing snakes and ladders but as multiples of 3s (so get two dice - so you can work to 3 x 12) and then move your piece that many multiples of 3. (Also with x3 your hand can be a calculator - Thumbs are tricky because you only have 2 creases so we also count the tip of thumbs, but there are 3 creases on each finger - so in fact you can count up creases (and thumb tips) to work out something like 3 x 3 (thumb: crease/ crease/ tip = 3 + finger (3 creases) = 6 + 3 more creases of next finger = 9).
Once you've got x3 you have virtually cracked it (honest) because you can get away with a lot by simply doubling.
x4 - use answer from x2 table but double it (so 8 x 4 is the same as 8 x 2 = 16 and double that = 32).
x6 - use answer from x 3 table but double it (so 8 x 6 is the same thing as 8 x 3 = 24 and double that = 48).
x8 - up to you if you know your x4 table well - just double it or go back to x2 but this time double it and double it again. so 8 x 8 is the same thing as 8 x 4 = 32 and double that = 64 ---- or 8 x 8 is the same thing as 8 x 2 = 16 and double that = 32 and double again = 64).
x 12 - again up to you - if you know your x 6 table well - just double it or you can go back to x3 and double and double again. So 8 x 12 is the same thing as 8 x 6 = 48 and double that = 96 or 8 x 12 is the same thing as 8 x 3 = 24 and double that = 48 and double that = 96. Alternatively you can think of x12 as the adding the result of x10 and x2 with that multiple - so 8 x 12 is the same thing as (8 x 10 = 80) + (8 x 2 = 16) and 80 + 16 = 96.
so at that point your DC knows: x0, x1, x2, x3, x4, x5, x6, x8, x10 and x12
that leaves x7, x9 and x11. x7 is horrid - so we'll leave that for last - but x9 and x11 are full of fun patterns (therefore once you know the trick they're easy to learn).
x9 - hand method for up to 9 x 10: There's a video with a catchy song which shows you this method
The other trick is to realise that with the 9 times table to x10 there is a pattern:
1 x 9 = 09
2 x 9 = 18
3 x 9 = 27
4 x 9 = 36
5 x 9 = 45
6 x 9 = 54
7 x 9 = 63
8 x 9 = 72
9 x 9 = 81
10 x 9 = 90
This first digit is always 1 less than the multiple
The two digits add to 9 - so the second digit is always whatever number you would have to add to the first digit to make 9.
so 8 x 9 - first digit has to be 7 so second digit is whatever number + 7 = 9 and that has to be 2 - so 8 x 9 = 72.
The other pattern with the 9s times tables (whatever multiple - even 9378 x 9) is that the digits in the answer always will reduce to 9 if added together:
9 x 9 = 81 and 8 + 1 = 9.
155 x 9 = 1395 and 1 + 3 + 9 + 5 = 18 and 1 + 8 = 9
(by the way similar trick to knowing if something is a multiple of 3 - if the number can be evenly divided by 3 it's a multiple of 3. So 1212 is a multiple of 3 because 3 can go into 1212 exactly 404 times. however that requires understanding division first and that's a ways off yet).
with 9 x 11 or 9 x 12 you can either count up
9 x 10 = 90 and 9 more is 99 for 9 x 11
or use the times table (because in fact you know 9 x 12 from your 12 times table - 12 x 9 = 9 x 12).
---------
x 11 is also a lovely pattern times table
like times 1 - you know up to x9 the multiple of 11 is just written down 2 times.
1 x 11 = 11
2 x 11 = 22
3 x 11 = 33
...
8 x 11 = 88
9 x 11 = 99
10 x 11 you should know anyway - is 110
at this point you may want to introduce what multiplying a number by 10 does - that everything moves over a column (jumps one column to left)
999 x 10 = moves 9 hundreds to 9 thousands
moves 9 tens to 9 hundreds
moves 9 units to 9 tens
and you put the 0 in the units place
999 x10 = 9990
(You can also teach what happens with x100 and x1000).
This is very old fashioned by way back in the day my teacher taught us to just count the zeros and add them on the end.
so 10,000 x 879 would be 879 + 4 zeros or 8790000 = 8,790,000
-------
anyway back to x11 and the trick with 2 digit numbers x 11
Take the first and second number and separate them and then put the two numbers together in the middle and that's your answer.
So with 14 x 11 - you get 1 - (1 + 4) - 4 = 154
it's a little tricky if you have to carry but it still works
38 x 11 = 3 - (3 + 8) - 8 = 3 - (11) - 8
you'll have to carry the 10 from the middle 11
so that gives you (3+1) - 1 - 8 = 418.
------
So that's all your times tables x0 - x6 and x8 - x12 except x 7
In fact you know times all the x7 table except 7 x 7 from knowing these other tables. I'm afraid there is no trick to knowing 7 x 7 = 49 except to know that 7 x 7 is a swine and that rhymes with 49.
================================
things you can do at home to help:
Great free websites:
Woodlands Junior Maths Zone - timestables: resources.woodlands-junior.kent.sch.uk/maths/timestable/ - lots of links to great games to help you practice.
Multiplication dot com: www.multiplication.com - again lots of games for practice.
-----
If you want to build up speed - there is a free version of a game called Timez Attack which casts your child as a young ogre working there way through a castle or dungeon solving multiplication problems (both as multiple additions and as traditional vertical problems). The game keeps track of what you get wrong and what you consistently struggle with and gives you the tricky ones again (so no faking it). You're tested by varying degrees of scary ogre. It did make DD2 shreek - but both DDs really got quick with their times table recalls and never viewed playing the game as practice. Link & info here: www.bigbrainz.com/.
There are more expensive versions with more platforms but we found the free version was enough.
Timez Attack also now has a division version of the game (so inverse multiplication facts - i.e. 36 divided by 9 is ? type questions). - which is the next step once tables are mastered.
--------
Old fashioned games:
As suggested above - use snakes and ladders to practice times tables - roll of dice (use 2 for up to x12) and just practice a specific table. We did find you had to play the board more than once for numbers >5.
As a family we play multiplication snap - so we would chose a times table to practice (maybe x 4) and use an ordinary deck of cards (Ace = 1/ 2 - 9 as numbered/ Jack = 10/ Queen = 11/ King = 12). Shuffle deck and place it face down. (I'd use a post it to write the times table down - in this case x4 - just as a reminder). Flip the card and the first to answer correctly gets to keep it. At first we were fairly gentle, but as they got better we really went for it. I fear we rather embarrassed ourselves by being too voluble in a restaurant when playing this waiting for our dinners - so I'd advise just playing this at home.

Times tables are a real hurdle that has to be cleared before progressing in maths. So much is dependent on it. But if you can do one thing in primary to give your child a headstart in secondary - ensuring they soundly know their times tables is it. So much of maths/ sciences at GCSE level depends on this core calculation skill: www.greatmathsteachingideas.com/2014/01/05/youve-never-seen-the-gcse-maths-curriculum-like-this-before/
