Picture logic, no reading required
Every puzzle at this level works entirely through pictures — a child doesn't need to read a single word to solve one, only to look carefully and compare. That's a deliberate constraint, not a limitation: at Pre-K and Kindergarten, the reasoning skill (comparing, matching, sorting, tracing a path) is what's being built, and requiring reading on top of it would test two skills at once instead of one.
Odd One Out
Each row shows four pictures — three identical, one different — and the task is simply to spot and circle the one that doesn't match. It sounds trivially easy to an adult, which is exactly the point: at this age, visual comparison across a full row (not just the item directly in front of them) is a genuine skill still being built, and getting faster and more confident at scanning a whole row before answering is real progress.
Size Sorting (Big or Small?)
A row shows the same picture at several different sizes, and the rule underneath — "circle the biggest one" or "circle the smallest one" — changes from row to row, so a child has to check the rule each time rather than falling into a habit of always picking the same position. That rule-check-before-you-answer habit is exactly what later, harder logic puzzles depend on.
Connect the Shadows
A numbered list of full-color pictures on the left is matched against a lettered list of solid black silhouettes on the right, and a child writes the matching letter next to each number. This is trickier than it sounds — some shapes have very similar outlines — and it builds a specific skill: recognizing an object by its outline alone, without color or detail to lean on.
Maze Puzzles
A small grid maze with exactly one path from Start to Finish through the walls drawn on the page. Every maze here is generated by an algorithm that carves a single guaranteed path (never a dead-end-only grid with no solution), so a child who gets stuck can be confident the path exists — the puzzle rewards careful tracing, not luck.
How to use this page with a Pre-K or Kindergarten child
Work through the first row or two together, saying the rule out loud before pointing ("we're looking for the one that's a different shape"), then let a child try the rest of the page independently. Short sessions beat long ones at this age — a few rows at a time, not a whole page pushed through in one sitting.
A teacher's guide to Pre-K and Kindergarten logic worksheets
Put four shapes in front of a three-year-old, three of them the same and one different, and ask which does not belong. Many children will answer at once, and some will answer with a delighted grin, because they have just done something that feels like a trick: they have seen a difference. It is the simplest form of logic there is, and it is the first step in a long road of reasoning.
This page gathers the four puzzles made for Pre-K and Kindergarten: Odd One Out, Big or Small, Connect the Shadows and the Maze. None of them needs a single word of reading. Every one works through pictures, and every one has a clear rule and one right answer. This guide explains what each puzzle is teaching, how to introduce it to a small child, how to help without taking over, and how these early puzzles grow into the reasoning of the later grades.
A Big or Small page. Under each row is a rule, either BIGGEST or SMALLEST, and the child circles the one that matches.
What logic looks like at this age
For a young child, logic is not about symbols or formulas. It is about noticing and deciding. Which one is different? Which is larger? Which picture matches? What is the way through? Each of these asks a child to look carefully, compare, hold a rule in mind and choose.
Several skills are developing at once.
- Visual discrimination. Seeing small differences between things that look alike.
- Comparison. Judging more and less, bigger and smaller.
- Categorization. Seeing what belongs together and what does not.
- Attention. Staying with a task long enough to complete it.
- Spatial reasoning. Understanding how shapes, paths and positions relate.
- Planning. Looking ahead to choose a route.
- Fine motor control. Circling, drawing a line, following a path.
- Language. Words like different, same, bigger, smaller, match, path.
None of these skills is taught by being told. They grow through doing puzzles, talking about them, and doing more.

Each puzzle has thirty numbered pages, and every page has a fresh arrangement.
Odd One Out
On each page, six rows show four icons. In every row, three are the same, and one is different. The child circles the odd one. The page in the main sample has a red triangle among green circles, a moon among blue circles, a blue circle among purple circles, a heart-eyes face among tongue-out faces, and so on.
An Odd One Out page. In each row, three icons match and one does not.
Why it works. The task is easy to understand, and easy to succeed at, but it is not trivial. To find the odd one, a child has to compare the four, decide what they have in common, and notice what breaks the pattern. The difference is sometimes in shape, sometimes in color and sometimes in both, and a child learns to attend to all of it.
Developmental levels.
- Beginning. A child finds the odd one when the difference is large: a triangle among circles.
- Developing. A child finds it when the difference is subtler: a blue circle among purple ones.
- Secure. A child finds it quickly, and can explain it: "They are all purple except this one, which is blue."
How to help.
- Point to the first two. "Are these the same?" "Yes." "And this one?" "Yes." "And this?" "No!"
- Use words. "Same, same, same, different."
- Ask for the reason. "How do you know it is different?"
- Make it physical. Lay out real objects, such as three red blocks and one blue, and ask which is the odd one.
Extensions. Make your own. Put three spoons and a fork on the table. Put three socks and one glove on the floor. Ask a child to make an odd-one-out for you, and then to explain what is odd about it.
Big or Small?
Each row shows five icons of different sizes. A rule sits beneath it: BIGGEST or SMALLEST. The child circles the one that matches. On the sample, the first row has five blue squares and asks for the biggest, the second has red circles and asks for the smallest, and so on.
Why it works. Size comparison is one of the earliest mathematical ideas, and it underlies measurement, counting and ordering. But the page adds something a plain "which is bigger?" does not: the rule changes from row to row. In one row the child looks for the largest, in the next for the smallest. That means the child has to read the rule every time, and not just repeat the last answer.
What a child learns.
- Comparative language. Big, bigger, biggest. Small, smaller, smallest.
- Following an instruction. The rule is a small piece of written text, which many children can recognize by its length and shape before they can read it, or a grown-up can read it aloud.
- Comparing more than two. With five items, a child has to compare many to find the extreme.
- Ordering. The ability to arrange things from smallest to largest is the beginning of number sense.
How to help.
- Read the rule aloud. "BIGGEST. Which one is the biggest?"
- Put your finger on the first and compare it with the next. "Which is bigger, this one or that one? Keep the bigger one. Now compare it with the next."
- Use real objects. Line up five blocks of different sizes, and find the biggest and smallest.
- Talk about "than." "This one is bigger than that one."
- Order them. Ask the child to line up the five from smallest to biggest, and see how the page's "biggest" is at the end.
A small trick for the youngest: a child who confuses big and small can be given a gesture, hands wide for "big," fingers close together for "small."
Connect the Shadows
Six pictures sit on the left, and six black silhouettes on the right, in a different order. The child draws a line from each picture to its matching shadow. The pictures are simple shapes: a diamond, a triangle, a moon, a star, a circle, a heart.
A Connect the Shadows page. The child draws a line from each shape to its matching silhouette.
Why it works. To match a colored picture to a black silhouette, a child has to see past color and attend to shape, the outline that is the same in both. That is a genuine visual skill, sometimes called form recognition, and it supports early reading, where a child must tell a b from a d by its shape alone.
What a child learns.
- Shape over color. The same form can appear in many colors.
- Matching. One-to-one correspondence between two sets.
- Visual memory. Holding a shape in mind while looking across the page.
- Pencil control. Drawing a straight line from one point to another.
- Elimination. Matching the easy ones first leaves fewer to choose from.
How to help.
- Start with the easiest. "Which one is the circle? Where is the circle's shadow?"
- Trace the outline with a finger. On the picture, then on the shadow.
- Use real shadows. On a sunny day, or with a torch, cast shadows of toys on a wall.
- Use cut-out shapes. Make shapes from paper, and lay them on silhouettes.
- Cross off. After matching one, put a tick by it, so the child can see what remains.
Extensions. Draw an outline of a familiar object, such as a cup or a toy, and ask the child to guess what it is. Make shadow puppets with a lamp.
The Maze Puzzle
A square maze has a Start in one corner and a Finish in the opposite one. The child traces a path through, with the pencil, without crossing a wall. The mazes are small, six cells across, with one route from start to finish.
A Maze page. There is exactly one path from Start to Finish.
Why it works. A maze asks a child to look ahead. At each junction, they must choose, and sometimes a choice leads to a dead end. The child learns to backtrack, to recognize that a path is blocked and try another. That is a powerful idea: that a mistake can be undone, and that exploring is part of solving.
What a child learns.
- Planning. Looking along a path before drawing it.
- Spatial reasoning. Understanding which way things lead.
- Flexibility. Changing course when something does not work.
- Persistence. Staying with it to the end.
- Pencil control. Staying inside the lines of a corridor.
How to help.
- Trace with a finger first. It is faster than a pencil, and it allows changes without marks.
- Try working backward. Starting at Finish is often easier, because the path from the end has fewer branches.
- Mark the dead ends. A small cross where a path stops saves time.
- Look ahead. "Where does this corridor go?"
- Use a different color. If the first attempt fails, a second color shows the new route.
- Keep it kind. If the child's pencil crosses a wall, just say "Oops, let's try another way."
Extensions. Make a maze with blocks on the floor. Draw a maze in chalk. Ask the child to make a maze for you, and see whether they can make a path that has only one route.
A sample ten-minute session
A session with a four-and-a-half-year-old, on an Odd One Out page.
- Minute 0 to 2. Warm up with real objects. Put out three red blocks and one blue one. "Which one is different?" Ask why. Do it again with socks, or spoons.
- Minute 2 to 3. Turn to the page. "What do you see? Shapes and faces. Our job is to find the one that is different in each row."
- Minute 3 to 4. Do the first row together. Point to each icon, saying "same, same, same, different!" Let the child circle the odd one.
- Minute 4 to 8. Let the child try the next two or three rows. Stay close, but quiet. When they answer, ask "How do you know?"
- Minute 8 to 10. Celebrate. Ask the child to choose which row was the trickiest. Put the page on the fridge.
A child who has done two or three rows with a smile has had an excellent session. There is no need to finish the page.
Everyday logic for little ones
The best logic practice does not need a page. Everyday life is full of small puzzles, and a child who is used to noticing them will find the worksheets natural.
- Laundry sorting. "Which socks go together? Which one is left over?"
- Tidy-up. "Put the biggest blocks at the bottom and the smallest on top."
- Setting the table. "Is there a spoon for everyone? Is there one too many?"
- Shopping. "Find the one that is different in this row of cereal boxes."
- Walking the way home. "Which turn comes next? Where does this road go?"
- Shadows. On a sunny day, look at your own shadow. Move, and watch it change.
- Treasure hunts. Follow a simple map around the garden or house.
- Snack choices. "Do you want the biggest apple slice or the smallest?"
These small moments build the same skills as a page: comparing, matching, planning and explaining. A parent who says "what do you notice?" a few times a day gives a child hundreds of practice moments a month.
Mazes and the idea of trying and backing up
A maze teaches a lesson that reaches well beyond maze solving. In a maze, a first attempt may fail. A path that looked promising may end at a wall. And that is fine. You back up, and try another way. This is the heart of problem solving, and it shows up in puzzles, science experiments, computer programming and life.
A teacher or parent can name it aloud. "That way is a dead end. Let's go back and try another." The calm language teaches the child that a dead end is not a failure but a discovery: now we know one route that does not work.
Children who learn this early are often more willing to try hard problems later, because they have learned that backing up is part of the process, not an embarrassment.
Developing the language of logic
A good logic lesson is also a language lesson. A few words and phrases are worth using again and again.
- "Same" and "different." The foundation of every classification.
- "Match." One thing corresponding to another.
- "Biggest," "smallest." The extremes.
- "Because." The word that turns an answer into a reason.
- "How do you know?" The question that asks for the reason.
- "Let's check." Verifying an answer.
- "What if...?" Opening up possibilities.
- "Path," "route," "dead end." The language of mazes.
A child who says "it's different because it's blue" is already reasoning aloud.
A routine for a puzzle
A very short, steady routine works well for small children.
- Choose a quiet moment. Not when the child is tired or hungry.
- Look at the page together. "What do you see?"
- Read the instruction aloud. "Circle the one that is different."
- Do the first one together, thinking aloud.
- Let the child do the next. Wait.
- Ask, "How do you know?"
- Celebrate the end. A sticker, a smile or a high five.
Five to ten minutes is a good session at this age. Many children will want to do just one or two rows, and that is fine.
What to watch for
A puzzle is also a window into how a child is thinking.
- Does the child look at all the options? Some jump to the first one. Encourage a scan.
- Do they explain? Even a few words show reasoning.
- How do they handle a mistake? Do they try again, or give up?
- How is their pencil control? Circling, drawing and tracing are all motor skills.
- Do they lose focus? Short sessions are better.
- Are they confident? A child who hesitates may need a simpler page.
- Do they enjoy it? Enjoyment is the best sign of a good fit.
Common difficulties and what helps
A child circles the first thing they see. Slow down, and point to each in turn. "Let's look at all four."
A child cannot tell what is different. The difference may be subtle. Use real objects to show the idea first.
A child confuses big and small. Use gestures and real objects.
A child draws wobbly lines in a shadow match. That is a pencil control issue. Practice with tracing pages, such as alphabet tracing.
A child gets stuck in the maze. Trace with a finger, and work backward.
A child gets upset by a mistake. Reassure: "Puzzles are for trying." Use a pencil with an eraser.
A child refuses. Do the puzzle together, or choose a different one. A child who loves mazes may be happy with a maze for a week.
Using puzzles for different ages
- Age 3 to 4. The youngest. Odd One Out and Connect the Shadows, one or two rows at a time. Use real objects first. Expect the adult to do a lot of the talking.
- Age 4 to 5. Full pages of Odd One Out and Big or Small. A first maze, traced with a finger. Short sessions.
- Age 5 to 6. All four puzzles with confidence. Mazes with a pencil. Ask for explanations. Start to move on to Grade 1 puzzles.
- Older children who need a gentle start. These pages are a respectful way to build confidence in a child who finds logic hard.
Connecting to the rest of the curriculum
Early logic work links to everything a young child is learning.
- Early math. Comparing size is the root of measurement and number. See the math worksheets and the number sense pages.
- Patterns. Odd one out is the flip side of a pattern: a pattern shows what repeats, and the odd one is what breaks it. See the emoji patterns.
- Reading. Matching shadows and spotting differences build the visual skills used to tell letters apart.
- Writing. Circling, tracing and drawing lines build pencil control. See the name tracing and alphabet pages.
- Science. Sorting, comparing and noticing are the first steps in scientific thinking.
For teachers
A Pre-K or Kindergarten classroom is a wonderful place for these puzzles.
- Centers. A page, a basket of real objects and a partner make a station.
- Small groups. Work through a page with three or four children, and let them explain.
- Circle time. A big puzzle on the board, and the whole class finds the odd one.
- Early finishers. A puzzle is a quiet, purposeful task.
- Observation. Watching a child do a puzzle shows how they think.
- Take-home. A page and a few blocks make a good family activity.
For parents
You do not need to be a teacher.
- Do it together. Sit side by side.
- Use real things. Spoons, socks, toys.
- Ask questions. "Which one is different?" "How do you know?"
- Keep it short. Five to ten minutes.
- Follow the child. If they love mazes, do mazes.
- Praise looking. "You looked at every one."
Questions that come up
My child is three. Is that too young? Not at all, with support. Use real objects first, and do one or two rows. Wait if the child is not interested.
Do the puzzles have answers I can check? Yes. Each has one right answer, visible on the page: the one that is different, the biggest or smallest, the shadow that matches, the path that reaches Finish.
My child circles the wrong one every time. Look at what they are choosing. They may have a different rule in mind. Ask them to explain.
Should I correct mistakes? Gently. "Let's look again." The aim is for the child to find the error.
How many a week? Two or three short sessions.
What comes next? Grade 1 logic, with cross-out grids and number patterns.
The first logic puzzles are small and friendly. But a child who has learned to say "this one is different, because..." has begun to reason, and every later puzzle will build on that beginning.
