You got credits for good work, and three credits were a merit and that went on the house total for the year. Debits were the minus equivalent. Then there was sports day and all that sort of thing
At primary school we were just allocated colours each sports day (held at the local dog track, PA supplied by the Army) and spent a morning making up rosettes, banners and so on, before being marched in a crocodile, singing "When the Saints go marching in", down to the track for all the usual egg and spoon, sack race etc. Winners of races got to choose a sweet from a big jar of chews/lollies etc.
