Today I shall be mainly "Putting the magazine to bed" and teaching small boys the mysteries of Fractions and the conversion thereof into Decimals.
So another fun packed day ahead 
oooh, can you teach me too - I was off sick that week... 
I am having to reteach myself as in my day we dealt with £s, shillings and pence, Imperial measures and the like. Remembering to divide by 10 rather than 12, that 1000 metres = 1 kilometre rather that 1760 yards making a mile etc means I have to stop and think things through rather than simply relying on hard learned mental skills that still come automatically. I know I should have "kept up" but I do recall a teacher once remarking that metric measurements were "only used by foreigners".
I do know how many chains make a furlong and still measure land in rods, poles and perches which I have to say completely baffled a local farmer when we were discussing the size of allotment plots that we could get out of one of his fields.
Hectares mean nothing to me but I can picture an acre and a cricket pitch should be 22 yards long!
