Fun Math Games: Children who play with numbers become children who understand them. That’s not wishful thinking; it reflects how the UK National Curriculum frames mathematical fluency: through reasoning, problem solving, and practical application, not just drilling facts. When a child realises that a six-digit number always collapses back to the three digits it started from, something clicks. The maths stops feeling arbitrary. It starts feeling like a language with rules they can actually explore.
LearningMole, the UK educational platform founded by former primary school teacher Michelle Connolly, has built hundreds of curriculum-aligned video resources around the idea that the most durable maths learning happens when children are genuinely curious about what the numbers are doing.
This guide brings together magic maths tricks and fun maths games that work for KS1 and KS2 children, both in the classroom and at home. Each trick includes the secret algebra behind the effect, because understanding why a trick works is where the real mathematical reasoning lives. The games are organised by the skills they practise: number bonds, multiplication fluency, place value, and mental calculation so teachers can use them as starters or plenaries without any prep time, and parents can adapt them for the kitchen table in minutes.
Whether you’re a Year 2 teacher looking for a no-prep activity that builds addition fluency, a parent trying to make homework feel less like a chore, or a child who wants to mystify friends with a number trick, you’ll find something here that earns an honest “how did that work?” The answer is always maths, and that’s the whole point.
Maths games and tricks are not a detour from serious learning. They are the learning when they’re chosen carefully.
The UK National Curriculum for mathematics sets out three core aims for every primary pupil: fluency (fast, accurate recall), mathematical reasoning (explaining and justifying), and problem solving (applying knowledge to new situations). A well-designed game addresses all three at once. A child playing Multiplication War is not just reciting facts; they’re comparing products, making quick decisions, and experiencing the consequences of errors in a low-stakes environment.
A child working through the 1089 trick is not just following steps; they’re confronting place value, three-digit subtraction, and reversal in a single exercise that feels like a performance rather than a worksheet.
Research in primary education consistently shows that game-based learning produces stronger retention than drill-based practice alone. The concrete experience of physically handling cards, dice, or a pencil-and-paper grid gives children a hook for abstract ideas.
When Michelle Connolly taught in primary classrooms, she found that children who struggled most with arithmetic were usually those who had never seen numbers on a page. Getting them to move, compete, and play was often what unlocked the understanding. The games below are chosen for exactly that reason: they give numbers a context children can grab hold of.
Magic tricks work in a maths classroom because they invert the usual dynamic. The child is not trying to find an answer that the teacher already knows; they’re watching something apparently impossible happen, and then being trusted with the explanation.
The effect: Ask someone to choose any three-digit number where the first and last digits differ by at least two (for example, 742). Tell them to reverse it (247), subtract the smaller from the larger (742 − 247 = 495), reverse the result (594), and add the two together (495 + 594). The answer is always 1089.
The maths behind it: This works because of the algebraic structure of three-digit numbers. If the number is written as 100a + 10b + c, the reversal is 100c + 10b + a. The difference is always a multiple of 99. The multiples of 99 that are three digits (099, 198, 297… 891, 990) all produce 1089 when added to their reversal.
Curriculum link: KS2, Years 4–6. Three-digit subtraction, column addition, and introduction to algebraic reasoning. Works well as a Year 5 or Year 6 investigation task.
In the classroom: Let children test whether it works for numbers where the first and last digits are the same (e.g. 343). It does not, and asking why is a rich reasoning task.
The effect: Ask someone to think of any whole number. Subtract 1. Multiply by 3. Add 12. Divide by 3. Add 5. Subtract their original number. The answer is always 8.
The maths behind it: The operations cancel each other out algebraically. Starting with n: subtract 1 gives n − 1; multiply by 3 gives 3n − 3; add 12 gives 3n + 9; divide by 3 gives n + 3; add 5 gives n + 8; subtract n gives 8. The original number vanishes completely.
Curriculum link: KS2, Years 5–6. Mental calculation strategies, inverse operations, and early algebraic thinking. A natural bridge into understanding why equations balance.
The effect: Choose any three-digit number (say, 213) and write it twice to make a six-digit number (213213). Divide by 11. Then by 7. Then by 13. The result is your original three-digit number.
The maths behind it: Writing a three-digit number twice creates a six-digit number equal to the original multiplied by 1001. And 1001 = 7 × 11 × 13. Dividing by all three factors, in any order, yields 1001, leaving the original number.
Curriculum link: KS2, Years 5–6. Multiplication, factors and multiples, divisibility rules. A strong hook for exploring prime factorisation.
Reverse version: multiply any three-digit number by 7, then 11, then 13 to create the six-digit repetition.
The effect: Ask someone to enter their birth month on a calculator (e.g. 4 for April). Multiply by 4. Add 13. Multiply by 25. Subtract 200. Add the day of birth. Multiply by 2. Subtract 40. Multiply by 50. Add the last two digits of their birth year. Subtract 10,500. The display shows their date of birth in the format MMDDYY.
The maths behind it: Each stage packs the month, day, and year into separate columns of a large number using multiplication as a positional “shift”, the same logic computers use to store date values. The subtracted constants are correction factors that strip out cumulative additions.
Curriculum link: KS2, Years 5–6. Mental and written multiplication, large number understanding, and place value to millions. Also, a useful discussion-starter about how computers handle dates. Note for teachers: verify this works with children’s actual birth dates before presenting it.
The effect: Give children a 3×3 grid with the numbers 1–9 arranged so that every row, every column, and both diagonals add to 15. Challenge them to find the arrangement.
The maths behind it: The 3×3 magic square using 1–9 has only one fundamental arrangement, though it can be rotated and reflected to produce eight versions. The magic constant equals n(n² + 1) ÷ 2, where n is the grid size.
Curriculum link: KS1/KS2. Addition and subtraction (KS1 with 1–9), multiplication (KS2 with the formula), symmetry and rotation. A strong reasoning task at every level.
| 2 | 7 | 6 |
|---|---|---|
| 9 | 5 | 1 |
| 4 | 3 | 8 |
Every row, column, and diagonal sums to 15.
The games below are grouped by the mathematical skill they most directly build. Each is marked with the key stage it best suits, and notes on whether it requires any equipment beyond pencil and paper.
| Game | Skill Practised | Key Stage | Equipment |
|---|---|---|---|
| Maths Facts Race | Addition / Subtraction | KS1, KS2 | Paper grids |
| Multiplication War | Times tables fluency | KS2 | Playing cards |
| Maths Facts Bingo | Multiplication recall | KS2 | Bingo cards, pencil |
| Stand Up, Sit Down | Any operation | KS1, KS2 | Number cards |
| Nim | Strategic subtraction | KS2 | Pencil marks or counters |
| 24 (card game) | All four operations | KS2 (Years 4–6) | Playing cards |
| Pig (dice game) | Addition, probability | KS1 (Year 2+) | One die per pair |
| Number Bond Snap | Number bonds to 10/20 | KS1 | In addition, probability |
Maths Facts Race
Divide children into teams. Post a grid of numbers (1–20 for KS1, 1–100 for KS2) at the front of the room. Call out an operation “multiply by 6” or “add 13” and one player from each team runs to write the answer next to a number on the grid. The first team to complete their grid correctly wins. Works equally well at the kitchen table with two players.
Nim
Place 15 pencil marks between two players. Players take turns removing 1, 2, or 3 marks. The player who takes the last mark loses. Nim rewards children who think ahead. Once children crack the strategy, ask them to explain why their winning approach works. This is mathematical reasoning in action.
Pig (Dice Game)
Each player rolls a single die and accumulates points by repeatedly rolling and adding results. On any turn, a player can “bank” their points, but if they roll a 1, they lose everything accumulated in that round. First to 100 wins. Pig teaches children to weigh risk against reward, with rapid mental addition throughout.
Multiplication War
Use a standard deck of cards with picture cards removed (Ace = 1). Both players flip two cards simultaneously and multiply their values. The higher product wins all four cards. High repetitions per session, self-correcting through competition, and no teacher input once children understand the rules.
The Game of 24
Deal four cards from a standard deck. Players race to make the number 24 using all four cards and any combination of addition, subtraction, multiplication, and division. Each card must be used exactly once. Year 5 and 6 children find this genuinely challenging; Year 4 children can play a simpler version using just addition and subtraction.
Number Bond Snap
Create a simple deck of number cards (0–10 for bonds to 10; 0–20 for bonds to 20). Both players flip a card simultaneously. If the two cards sum to the target, the first player to shout “Snap!” wins the pile. Drills number bonds at KS1 without a worksheet in sight.
Maths Facts Bingo
Create bingo cards with answers to multiplication table facts. Call out equations rather than numbers, “3 times 8” rather than “24”. Children mark their cards when they work out the answer that matches their grid. Forces active computation rather than passive number recognition.
Stand Up, Sit Down
Give each child a number card. Call out an equation. Any child whose card matches the answer stands up and stays standing until the next equation is called. Vary the operations and difficulty. Works for addition in Year 1, all four operations in Year 6.
LearningMole’s curriculum-aligned video resources cover maths topics across EYFS, KS1, and KS2, including number patterns, multiplication, place value, and mental calculation strategies. The videos work well alongside the games above, with a quick explanation of how a magic square works on screen, followed by the hands-on activity with the class.
For parents, the videos are a reliable way to reinforce what children are doing in school without needing to know every method being taught. Each video is designed for independent viewing and whole-class teaching.
“Children learn mathematics best when they can see it in action, not just read it on a page. A game makes the maths visible. A trick makes it memorable. And when children start asking why a trick works, they’re doing exactly the kind of mathematical reasoning the curriculum asks for.” Michelle Connolly, Founder of LearningMole and former teacher with over 15 years of classroom experience

Children who develop strong mental calculation habits find the games above more enjoyable and the tricks more accessible.
Watching maths explanation videos alongside games and tricks builds the conceptual understanding that makes mental calculation feel easier. When children understand why 7 × 8 = 56 rather than just memorising the fact, they’re less likely to confuse it with nearby facts and quicker to reconstruct it if they forget.
Most of the tricks in this guide suit children aged 7 and above (Year 2 upwards), though the Magic Square Challenge works at the KS1 level with simple additions. The 1089 trick and Birthday Number trick are best for Years 4–6, when children have secure three-digit arithmetic. Younger children can enjoy the ‘Always 8’ trick with a calculator to handle the computation while they follow the sequence of steps.
The National Curriculum for mathematics in England identifies three core aims: fluency, reasoning, and problem solving. Well-designed games address all three simultaneously. Multiplication War builds fluency through high-repetition practice; Nim develops reasoning through strategic thinking; the 24 card game requires problem solving with all four operations. Games are not a substitute for direct teaching, but they provide the practice and application context the curriculum describes.
Yes. Maths Facts, Race, Stand Up Sit Down, and Nim require only a pencil and paper or a set of number cards, all of which are standard classroom resources. Multiplication War and the 24 game need a single deck of playing cards. None of the games in this guide requires printing, laminating, or advanced preparation beyond reading the rules once.
Pig (the dice game), Number Bond Snap, and Stand Up Sit Down all work well for Year 2. Pig reinforces mental addition and introduces risk-based decision making in an accessible way. Number Bond Snap drills bonds to 10 and 20 at a pace that matches children’s needs in Year 2. Stand Up Sit Down can be calibrated to whatever operation the class is currently working on.
The ‘Always 8’ trick and the six-digit repetition trick work well at home because they need no equipment beyond a pencil and paper. Start by performing the trick on a parent, then explain it and let the child perform it on someone else. The second step, teaching the trick to another person, is where the mathematical understanding deepens, because children have to explain the steps accurately rather than just following them.
Yes, for Years 4–6. It uses three-digit subtraction and column addition, both of which are covered by Year 4 in the UK curriculum. The algebraic explanation is accessible to Year 5 and Year 6 children who have been introduced to the idea that letters can represent unknown numbers. Teachers often use it as an investigation: children test multiple starting numbers, record results, and spot the pattern before being shown why it works.
This is common when games are too difficult or the competitive element feels high-stakes. Reduce the pressure by playing cooperatively first, both players working together to reach a target rather than against each other. Reduce the difficulty by using smaller numbers than the game specifies. Let children choose their favourite game from a short list rather than imposing one; ownership makes participation more likely.
Stand Up Sit Down needs only number cards, which can be written on paper scraps. The ‘Always 8’ trick needs nothing; the child can do the calculations in their head or on paper. Nim can be played with pencil marks on the back of any piece of paper. For classroom assemblies or outdoor learning, these are particularly useful because nothing needs to be brought from a classroom resource cupboard
Maths games and tricks work because they shift the emotional context of calculation. Numbers that felt like tests become numbers that feel like puzzles, and children who approach puzzles with curiosity learn more than children who approach tests with anxiety. The tricks in this guide give children a way to build confidence before they’ve fully built it, and performance, practised enough times, tends to become the real thing.
The games here do not require children to be good at maths before they can play. They require children to do maths in order to play, which is a different thing entirely. Multiplication War does not care if a child is still learning their sixes; it gives them a reason to care and a low-stakes environment to practise in. That’s what good maths resources do: create the conditions where children choose to engage with number, rather than waiting to be told they have to.
LearningMole’s maths video resources are available across EYFS, KS1, and KS2, designed by educators who understand what primary classrooms actually need. Whether you’re a teacher planning a series of lessons or a parent looking for something useful to do on a long weekend, the curriculum-aligned videos and activities are there to support the learning that happens alongside the games and to answer the question children always ask when a trick works: “But why does it do that?”
LearningMole provides free and subscription-based educational videos and resources aligned with the UK National Curriculum. Whether you’re a teacher planning lessons, a parent supporting home learning, or an educator seeking quality materials, the library covers maths, English, science, and much more.
