The Eight Times Table

The Eight times table is proving difficult for Harry.  Hopefully after this weekend he is a lot closer to remembering it.  I can't believe he had arrays as maths homework.  As long as he never has to do metrices.  I never saw the point of them and have never used them.


  1. last night I dreamed of Charlie. He was an actor in America, and he called another boy American Harry, because that boy was very nice to him and took care of him.

  2. The 8 times table is one of the most difficult to learn. At least there are some good tricks for the 2, 3, 4, 5, 6, 9, 10, and 12 times tables though.

    To tell if a number goes into 2 only even numbers go into 2. So the number must end either in 2, 4, 6, 8 or 0.

    To tell if a number goes into 3, add the digits. If the sum you get is divisible by 3, then the number itself must be divisible by 3.

    To tell if a number goes into 4, the last two digits of the number must be divisible by 4, or both be 00. This is because 4 goes into 100 exactly.

    For a number to go into 5, the number must end in 5 or 0.

    For a number to go into 6, 6 is equal to 2 x 3. Therefore the number must be even, and then the numbers seperate digits added together must be divisible by 3.

    For a number to go into 9, add all the digits together and if the digits add up to a number divisible by 9, than the number itself is divisible by 9.

    For a number to go into 10, it needs to end in 0.

    For a number to go into 12, 12 is equal to 3 x 4, so first you need to add the digits to see if 3 goes into the number, and then check if the last two digits are divisible by 4.

    However there are no tricks for the 7, 8, or 11 times table, Harry will just have to learn those.

    Good luck with it anyway. I remember having to learn my timestables myself.

  3. Hi Daivd - he got his 8's - horrah. Three's now and he seemed to have got them in the first couple of days :)
