Printable number chart, 1 to 50

What this sheet holds

The chart sets the whole numbers from 1 to 50, one to a cell, in a grid ten columns wide and five rows deep. Fifty numerals on a single A4 sheet at fifteen point, inside seventeen ruled lines: eleven running down the sheet and six running across it. Nine of the numerals are single digits; the other forty-one have two, and none has three.

The rows read 1 to 10, 11 to 20, 21 to 30, 31 to 40 and 41 to 50, and 50 closes the fifth row in the bottom right corner.

Exactly half a hundred square

Fifty is half of a hundred, and ten to a row is what makes that halving land cleanly. Five rows of ten is fifty, so this sheet is the top half of a hundred square with the cut falling along a ruled line: no row is broken and no cell is split. The other half, 51 to 100, is the same shape again underneath.

Everything the wider sheet does in ten rows, this one does in five. A step of one cell to the right adds one. A step of one cell down adds ten. Each column is a run of tens and every number in it ends in the same digit, but the run is five long instead of ten: 1, 11, 21, 31, 41 down the left-hand edge, and 10, 20, 30, 40, 50 down the right, which is the ten times table stopped at its fifth term.

The diagonals halve with it. Down and to the right adds eleven, so that line reads 1, 12, 23, 34, 45 and then runs off the bottom of the sheet where a hundred square would carry it on to 100. Down and to the left adds nine.

What the half sheet keeps is every property that comes from the width, since those depend on the row being ten cells long and not on how many rows follow it. What it does not carry is the second half of the tens. The right-hand column stops at 50, and 51 to 100, which would take it down to the corner of a full hundred square, are simply not on the sheet. Changing the range on the page puts them back.
