    Who Needs Times Tables?

    By Enniskillen Royal | Latest News | Comments are Closed | 31 January, 2017 | 1

    Whether you are in ordinary Maths lessons in Year 8 at ERGS or studying Further Maths in Year 14 in preparation for a mathematical course at university, being able to instantly call to mind your times tables is important. Take a look below at where you will need to know, for example, that 7 x 9 = 63.

    Year 8

    Question             5.7 x 9

    Ans                        7×9 =…

    Year 9

    Question             Expand:                                7(2x + 9y)

    Ans                        14x + …

     

    Year 10

    Question             The nth term of an arithmetic sequence is given by the expression  7n – 5.

    What is the 9th term of the sequence?

    Ans                        7 x 9 – 5 = …

     

    Year 11

    Question             Write the answer to the following calculation in standard form: 700000 x 0.009.

    Ans                        7 x 9 = …

     

    Year 12

    Question             A cylinder has a diameter of 6cm and a height of 7cm. Find the volume, leaving your answer in terms of π.

    Ans                        V             = π(r^2)h

                                                    = π x (3^2) x 7

    = π x 9 x 7

    = …

    Year 13

    Question             Find the equation of the normal to the curve given by the equation y = 9x^7 + 1

    at the point (0,1).

    Ans                        Gradient of curve            = (7×9) x^6

    = …

    Year 14 (Further Maths)

    Question             Find an equation for the plane through the origin which contains the lines L1 and L2 with the following equations:

    L1:          r = t(2i + 9j + 3k)                                L2:          r = s(-i + 7k)

    Ans                        n             = (2i + 9j + 3k) x (-i + 7k)

     

    = (9×7)i + …

     

    All of the above answers have stopped at the point where 7 x 9 is needed. Knowing instantly that this is 63 has at least two advantages:

    • It stops you becoming distracted from the larger method you are following (you can see that from Year 8 to 14, basic skills are used in increasingly complex situations);
    • It saves time compared to typing the calculation into your calculator (if allowed!). Most tests will involve lots of basic operations – if you know your tables instantly this can add up to a lot of time saved.

    So, to improve your recall of times tables, take a look at the Multiplication Drills resource on Fronter. Doing one of these a week will help you recognise answers with greater speed and help you work through problems, at whatever level, more smoothly.
