If I were to be asked the most important skill associated with passing external examinations at age 16 or thereabouts, I would say without any shadow of a doubt it is a good knowledge of times tables. Through the thirty years of my teaching career, We have come across numerous students (in schools so that as private students) who have no idea their times tables at age 16 good enough so that you can calculate things such as a fifth of 45 or perhaps the total length of 8 ropes, each 4.5 metres long. - times tables worksheet
The points I make have universal relevance across the whole world, even though i write as a teacher in the UK, so my examples relate specifically to this country. We have a system of examinations now by which there exists nearly always a calculator examination paper and a non-calculator paper at each and every level from age twelve. So, is of great benefit in the calculator paper too, as knowing that seven eights is fifty six is much less time consuming than having to press the appropriate buttons on a calculator, even though a good knowledge of tables is definitely needed in the non-calculator paper. Inside an examination, seconds count.
A moment's thought will reveal most of the instances where times tables are utilized. Every money problem in any currency involving a multiplication ($12.67 x 9) or division (Discover the average of $34.50, $33.60, $59.90 and $46.80) uses times tables. Percentages (Find 17% of 12.50), fractions (cancel 45/75 to its lowest terms), geometry (get the internal angles of a regular octagon), algebra (expand 7a(3a 6b 9c)) and speed problems (find the average speed of the car that travelled 960 kilometres in 8 hours) are just a few of the various more examples available on examination papers.
Just one way of practising times tables is to complete random tables squares, i.e. tables squares in which the numbers 1-10 are distributed randomly across the top of the the table and on the left hand side. I am just currently using a selection of 8 and 9 year olds in a local primary school, a number of whom can already complete this kind of table correctly within 5 minutes. At sixteen yrs old, the great majority of students will be able to easily beat that point - and acquire every one of them correct, needless to say.
The question of whether times tables from 1 to 10 is plenty often crops up. Should youngsters be aware of twelve and eleven times tables? If you live in a mostly metric country, 1 to 10 is sufficient for all examination work and I would then concentrate on learning the square numbers up to 20 x 20 as these are very useful for Pythagoras' Theorem. If you live in a country still using inches and feet for everyday measurements, then you will probably need to learn tables up to 12 x 12.
So, if you or your youngsters are taking external examination some time soon, the one thing you could do to improve your performance more than anything else is to get those tables truly and well in the old brain box!
