It all starts at the round calendar in the middle of the board. The child turns the pointer to the month of their birthday, then sets the clock to the current time and marks today's weather - three moves, three different measures of time. Why 12 months and 365 days? The Egyptians noticed a year of this length around 3000 BC, Julius Caesar added leap years, and in 1582 Pope Gregory XIII shortened the calendar by 10 days and established the one still in use today. Without a textbook, the principle behind the calendar becomes clear: nature comes back in a repeating rhythm.
Setting the date every day only makes sense if the board can withstand rain, frost and sun. The frame is galvanised and powder-coated, the moving pointers are made of metal that does not rust, and the print is protected by a UV-resistant varnish, so the colours do not fade in the sun. The pointers work without batteries or electricity - the mechanism is as simple as in an old clock. The mounting height is adjustable, so the equipment grows with the group: at one time it stands at the height of a nursery child, at another at that of a pupil. The board works outdoors all year round, winter included, and is covered by a warranty. The manufacturer is EduPlayground, and the board is made in Poland.
Four panels measure different things, and the board takes magnets from themed sets.
