How to learn my times tables...?

Question

quickly and efficiently? I need to learn my 4,7,9 times tables for school because we do times table grids at the start of each maths lesson and i always come at the bottom of the class because i don't know my 4,7,9 times tables. I sort of know my eights but weather it'll stick in my head or not i don't know. So how can i learn my times tables quickly and easily?

Answer 1

If you think of fours as multiplying by 2 twice, it helps.



2x2x4= 16

4x4= 16



Sevens are harder. If you know your 6 times tables, you can add the number you're multiplying by 7. For example:



6x5=30

30+5=35

7x5=35



6x12=72

72+12=84

7x12=84



Nines have a couple tricks to them.

If you have trouble with nines, multiply the same number by 10 and subtract that number from the total afterwards.



5x10=50

50-5=45

5x9=45



8x10=80

80=8=72

8x9=72



Also, if you add the two digits in a 9s table together, you'll get 9 (or 18, or 27, or 36 etc. once you get to bigger numbers. You'll always get a multiple of nine). Its a good way to check your work on the 9s.



5x9=45

4+5=9



12x9=108

1+0+8=9



Hope this helped and wasn't too complicated.

Answer 2

Wow.



4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48 - Double 2 times table

7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84 - No handy trick for this one that I know of.

9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108 - Each adds up to 9 or 18 (72, 7+2=9, 108, 1+0+8=9)

Answer 3

The 9 Times Quickie



1. Hold your hands in front of you with your fingers spread out.

2. For 9 X 3 bend your third finger down. (9 X 4 would be the fourth finger etc.)

3. You have 2 fingers in front of the bent finger and 7 after the bent finger.

4. Thus the answer must be 27.

5. This technique works for the 9 times tables up to 10.



The 4 Times Quickie



1. If you know how to double a number, this one is easy.

2. Simply, double a number and then double it again!

Answer 4

for your 9's times table theres a simple way but it could be hard to explain so ill just use an example and hopefully you will understand..



for 3x9 put ten fingers in front of you with the palm facing you and put your 3rd finger down, you will have 2 fingers up at the left side, and 7 up at the other,

the answer to 3x9 is 27

for 4x9 put your 4th finger down and you should have 3 and 6 and the answer is 36.



you can do this with 1x9, 2x9, 3x9, 4x9, 5x9, 6x9, 7x9, 8x9 and 9x9.



this method helped me alot in school and i hope it helps you too :D

Answer 5

i can help you with the 9 times tables. all you need is to look at the fingers on your hand.

say for instance you want to find out 9x6,

you put your 6th finger down.

the fingers before the one you put down go up in tens

the ones after the one you put down go up in ones.

therefore it would be 50... and 4... so it equals 54.



does this make sence?
