Which square sizes are there?

1 inch, ½ inch, 1 cm, ¼ inch and 5 mm. On the two smallest grids every fifth line is a little darker, so squares are easy to count.

What is squared paper good for in primary school?

Lining up digits in column addition and subtraction, drawing arrays and area models, bar graphs, and pixel art.

Is the paper the right size when printed?

Yes, as long as you print at 100% scale (Actual size). Fit to page would shrink the squares a little.

Graph paper for maths

Children who write each digit in its own square line up ones, tens and hundreds without trying. Pair it with the addition and subtraction worksheets when regrouping starts.

In the MOE curriculum

Primary 1Copying figures on dot grid or square grid paper.
Primary 3Measuring area in square units and cm², which 1 cm squares make concrete.
Primary 4Completing symmetric figures on square grid paper, and drawing rectangles and squares.

On 1 cm paper every square is exactly 1 cm², so Primary 3 children can draw a rectangle and count its area before they learn to multiply length by breadth. The syllabus says “breadth” where many countries say width, so use the same word on the board.

For P4 line symmetry, draw half a figure on one side of a line and have a partner complete it. Isometric grid paper, which the syllabus uses in Primary 5 for drawing cubes and cuboids, is not offered here.
