Free Symmetry Worksheets for Grade 1 – Draw the Other Half

Free Symmetry Worksheets for Kindergarten – Draw the Other Half

These free printable symmetry worksheets help kindergarten and first grade children learn about lines of symmetry. Each page shows half of a picture on a grid, with a red line down the middle that works like a mirror. Children color the boxes on the empty side so that both halves match, and a symmetrical shape such as a heart, a star, a tree, or the sun appears. Because the picture sits on a grid, kids can count boxes from the mirror line to place each square exactly. Symmetry is an early geometry idea that also builds careful looking and counting. The final page is an answer key. Just download, print, and finish the picture!

Drawing the other half: symmetry as a mirror, not a copy

Completing a symmetrical picture is not the same as drawing the shape again on the other side. Every point has to sit the same distance from the line as its partner, and facing the other way. Children who treat the task as copying produce a picture that looks roughly right and is not symmetrical at all.

What your child is actually learning

Symmetry work at this age builds spatial reasoning: holding a shape in mind, reflecting it, and reproducing it accurately. The mirror line is the key idea, and the useful rule is about distance. If a corner sits three squares to the left of the line, its partner sits three squares to the right. Grid paper makes this countable rather than approximate, which is why these pages use it.

How to work through these pages

Use a small mirror if you have one, stood upright on the line. Seeing the completed picture appear in the mirror before drawing it turns an abstract instruction into something observable. When drawing, work point by point rather than shape by shape: find one corner, count the squares to the line, count the same number the other way, mark it. Joining the marks at the end is the easy part.

The mistakes to expect

Copying rather than reflecting, so the second half faces the same way as the first. This produces a repeated pattern instead of a mirror image.
Getting the shape right but the distance wrong, so the drawing is lopsided.
Ignoring the grid and drawing freehand. The squares are there to be counted.
Working shape by shape and losing accuracy. Point by point is slower and much more reliable.

What to teach next

Deciding whether a given line actually is a line of symmetry is the natural partner task, and it tests the same understanding from the other direction. Beyond that, finding symmetry in the real world — leaves, faces, letters, buildings — keeps the idea alive between lessons.

Questions parents ask

Does the mirror line always have to be vertical?

No. It can be horizontal or diagonal, and a diagonal line is much harder. Most first grade work uses vertical lines, which is the sensible place to start.

My child’s drawing is neat but not symmetrical. What is going wrong?

Almost always the distance from the line rather than the shape. Ask them to count the squares on each side for one corner and compare; the error usually becomes obvious to the child immediately.

Is this maths or art?

Both, and that is part of why it works. The reasoning is geometric, and the fact that the result is a picture keeps children engaged with a task that is genuinely demanding.
