Have a look at these timesavers.
There’s no easy trick for finding out if a number is in the 6 × table, but here are some tips:
All the numbers in the 6 × table are even - they end with 0, 2, 4, 6 or 8.
They are all a multiple of 3; they can be divided by 3.
The digit sum is always 3, 6 or 9
You can work out a 6 × calculation by multiplying the number by 3 (tripling it) and
then doubling your answer
5 × 6 is the same as 5 × 3 = 15, then 15 × 2 = 30.
(You can also do this the other way round: 5 × 6 = 5 × 3 × 2 = 15 × 2 = 30.)
You can reverse the calculation if that makes it
easier. Have a look at these coins.
There are 8 piles with 6 coins in each.
This is 8 lots of 6 or 8 × 6.
Count them up - there are 48.
Now reverse the calculation so you have 6 piles
with 8 coins in each - 6 lots of 8 or 6 × 8.
The number of coins is the same.
