Maths homework help please

For the 9 times table you can take one from the number of times and add the number that adds up to 9.
eg. 7x9 So take one away from 7 which makes 6 and you need 3 to make make 9 so answer is 63.
5x9 (take 1 away from 5) that leaves 4 and 5 is needed to make 9 so answer is 45.

Pay someone to do your assignment sounds like cheating to me. Are you really recommending that?

I learnt times tables 70-odd years ago and have never forgotten them in all this time. But these ingenious ways of understanding numbers were never a feature in those years. I loved languages and understood them as patterns whereas I never found the patterns of maths. I passed Lower Maths easily without loving the subject. It was a matter of learning and applying the formulae without any depth of understanding.Is it too late now?

This thread is over eight and a half years old. Presumably Ginny42's DGS has mastered his times tables by now. He is probably in his teens.

I was going to say that Magenta, it ll never let me on old threads always says they ve ‘moooved’ I don’t understand how people find them

You can explain /point out to children that many of the times tables are magic.

4 x 12 = 48
12 x 4 = 48.
2x 24 = 48
It's blindingly obvious to people who know all their tables and confidently manage numbers... but for those who don't, often very surprising andenlightening.

You can play games at home to illustrate this, using a bowl of dried beans or pegs or beads

"Lets make 4 piles of 6 beans. How many altogether?
Now show me 6 x 4.
Now lest make them into 2 x 12.

12 x 2.. 3 x 8

Everyday life is full of ways to play with number. Set the table for dinner. How many people are coming to dinner? How many knives/forks.spoons/mats/glasses etc.

In the car, you can play countless games with the numberplate of the car in front (multiply the first two numbers), "add the first two numbers". etc

From a very early age I thoroughly recommend playing dominoes, and dice board games like snakes and ladders, snap with an ordinary card pack, so that even small children acquire a grasp of counting and matching, number recognition etc.

This is an old thread but anyway I never learned my times tables and now working out things like 7x8 in my head takes me ages!

I don’t know if this would be helpful. We used Cuisinaire blocks to teach basic concepts of maths to our children They are I cm to 10 cm wooden blocks, each being a different colour. They are so good at taking the mystery out if maths. For instance line up 5 10 cm blocks = 50 cm. Then see how many 5 cm of blocks it takes to be the same legth = 10. You can do adding, subtracting, multiplication etc. we passed them on to the GC who had fun with them.

If you know 7 × 4 = 28, double it

The way I would do it would be to think of 6x8= 48 because that is 5x8=40+8 equals 48 then add another 8 48+8 =56.

I usually get there in the end!
