Looking carefully: spot the difference, mazes and puzzles

By Pencil Oak · October 3, 2026

Spot the difference, shadow matching, mazes and picture puzzles all ask the same thing of a child: look closely, compare, and keep looking until you find the answer. Teachers call this visual discrimination. For a five-year-old it means noticing that two pictures are not quite the same, that one shape fits a shadow and another does not, or that one path is a dead end. These are quiet, satisfying activities, good for a calm moment in the day.

The hard part for the grown-up is helping without solving the puzzle for the child. This guide shows how to do that for each kind of puzzle. Each takes five to ten minutes, and the child can stop when they have had enough.

This is a general routine, not an assessment. If you are worried about how a child sees or notices things, talk to their teacher or doctor.

Before you start

Step 1: Match real things first

Before pictures, play with objects: find the matching sock from a pile, sort spoons from forks, find two leaves that look alike. Play "I spy" with colors and shapes. This teaches the idea of "same" and "different" in a way the child can hold.

Step 2: Match a picture to its shadow

In shadow matching, each picture has a dark shape that is its outline. The child draws a line from the picture to the shadow it fits. Teach a simple way to look: pick one picture, look at its outline (is it tall, round, does it have ears?), and then check each shadow against it. The first pair is often done as an example, to show how it works.

Step 3: Spot the difference

A spot the difference sheet shows two pictures made of the same things. In the lower one something has changed: a picture has a different color, a different picture has taken its place, or a picture is missing. Teach the child to look place by place: top left in the first picture, top left in the second, and so on, row by row. Start with three differences and add more later. Circling each one as it is found stops the child from finding the same one twice.

Step 4: Find the way through a maze

Start with the finger: trace the path from the start to the end before using a pencil. Then use a pencil, lightly, without lifting it. Tell the child to look ahead a little, because the best way to avoid a dead end is to see it coming. If they are stuck, try starting from the end. An easy maze has wide paths and few turns, and the harder ones have more of both. Drawing along the path is also good practice in controlling the pencil.

Step 5: Build a picture puzzle

In a cut-and-glue puzzle, the child cuts out the pieces and puts them in the frame to make the picture. A frame with a faint picture in it is the easiest, since each piece can be matched to the faded picture. When that feels easy, switch to a frame with only the squares. Suggest a strategy: first find the piece that has the head, or the piece with a corner. Number labels under each piece help a grown-up check the answer afterwards.
