About this paper
Decimal grid paper
Each block is a hundred grid: 10 × 10 small squares with a heavy outline and a slightly bolder line through the middle at 5. One whole block is 1, a row or column is a tenth (0.1) and a single square is a hundredth (0.01), which makes it easy to shade 0.37 or 45%.
Blocks are separated by a one-square gap so each one can be labeled or cut out. With 4 mm squares a Letter page holds 20 hundred grids; larger squares give fewer, bigger blocks.
