Half of a picture is already drawn on the grid, and the other half is missing. Can your child finish it so both sides match perfectly? In this free symmetry activity, children look at the mirror line down the middle, count squares from the line, and shade the matching squares on the other side.

The 8x8 grid is a friendly size for children aged 8 to 10. It is big enough for interesting pictures, yet simple enough to check square by square. Play it on screen or print it for quiet desk work at home or in class.

How to play

  1. Look at the mirror line (the line of symmetry) in the middle of the grid and the half picture beside it.
  2. Pick one coloured square. Count how many squares it sits away from the mirror line.
  3. Count the same number of squares on the empty side and shade that square.
  4. Repeat for every square, then fold or check with a mirror to see if both halves match.

This activity gives children hands-on practice with reflective symmetry, one of the first ideas in geometry. By counting squares away from the mirror line, your child learns that a reflection keeps distance and shape the same but flips direction. It also strengthens careful counting, left-right awareness, grid reading and neat pencil control, all useful later for coordinates and graphs. Mistakes are easy to spot and fix, so children build confidence in checking their own work. For extra practice, ask your child to draw their own half picture on grid paper and let you complete the mirror side.

Frequently asked questions

What is a line of symmetry?
A line of symmetry is a line that cuts a shape or picture into two matching halves. If you fold along that line, the two halves sit exactly on top of each other, like a reflection in a mirror.
Which age is this grid symmetry activity best for?
The 8x8 grid suits children aged about 8 to 10, who can count squares confidently. Younger children aged 6 to 7 usually do better with a smaller 6x6 grid and simpler half pictures.
How can my child check the answer?
Ask them to count squares from the mirror line on both sides, row by row. A small mirror placed on the line, or folding a printed sheet along the line, shows straight away whether the two halves match.
Can I print this activity for a classroom?
Yes. The worksheet is free to print and use at home or in school. Print a set for group work, laminate a few copies for whiteboard markers, or send sheets home as light geometry homework.
