Doubles Addition Games: 10 Playful Ways to Master 1+1 Through 10+10
Ten doubles addition games for ages 6–8 that make 1+1 through 10+10 stick for good: mirror matching, double dice, domino doubles hunts, card slap, pair hunts, ten-frame twins, snack doubles, doubles bingo, hopscotch, and an honest bridge to doubles-plus-one. Every game sets up in minutes with things you already own.
The best doubles addition games make both addends identical, so children spot the pattern fast: mirror-matching counters, rolling one die and doubling it, and hunting doubles in a domino set. Play for 10–15 minutes, say every fact aloud ("7 + 7 = 14"), and add doubles-plus-one only when the ten core facts feel easy.
The short version
- Doubles (1+1 through 10+10) are the first facts worth memorizing — nearly every "near double" like 7+8 is solved from a double.
- Say the full sentence every time: "6 plus 6 equals 12." Saying it aloud moves it into memory.
- One game, 10–15 minutes, daily — short sessions beat long ones.
- Mirrors and pairs make the "sameness" visible, and the sameness is the whole concept.
- Save doubles-plus-one until the doubles underneath are automatic.

Why kids love this
Because every game is about spotting twins. Matching trays, slapping cards, hopping paired squares, hunting dominoes, eating identical bowls of crackers — nothing here looks or feels like practice. Children come back because the games are fun, and the doubles come along for the ride.
What you'll need
- Two identical small trays, plates, or bowls (for Mirror Match)
- Counters: dried beans, large buttons, pom-poms, or pennies
- One ordinary die (a 10-sided die is a nice upgrade later)
- A double-six set of dominoes
- A deck of playing cards (face cards removed)
- Shoes, socks, and gloves for the pair hunt
- Paper, crayons, and a ruler (ten frames and bingo cards)
- Snacks: crackers, berries, or cereal pieces
- Pavement chalk (for the hopscotch game)
- Buttons or coins as bingo markers
Before you start
Two minutes: set out the twin trays and a bowl of counters for Mirror Match, with the domino box and cards within reach for later games. The pair hunt needs zero setup — just point at the hallway. Draw the ten frames and bingo grids together with your child; making the materials is part of the math.
How to do it
-
Set out the twin trays. Place two identical small trays, plates, or bowls side by side on the table where you both can reach them, and give them their name together: "These are the twin trays." They need to match exactly — same size, same shape — because the whole game is about sameness, and your child should see it before a single counter appears. Put the trays where your child sits opposite you, not beside you, so the mirror idea is obvious from the start.
-
Put the counters between you. Set a small bowl of counters — dried beans, large buttons, pom-poms, or pennies — in the middle of the table, within easy reach of you both. Say the plan out loud: "We are going to make both sides match, every single time." Let your child run a hand through the counters first; the feel of them is part of the invitation, and a child who has handled the materials is already halfway into the game. If your child is still building 1 to 10, start with these counting to 10 activities and come back to the trays once the counting feels steady.
-
Place four and say match me. You go first so your child can watch the whole move before trying it. Place four counters on your tray, one at a time, counting as you go, and say the line that starts every round: "4 on my side — match me!" Keep your tray visible and your voice playful; this first placement is the model your child will copy, so make it slow and clear rather than quick.
-
Let your child copy the four. Now it is your child's turn to do the matching: they place exactly four counters onto the other tray, one by one. If they place three or five, do not correct them straight away — ask, "Does your side match mine?" and let them count both trays and fix it themselves. The moment the two sides match is the moment the doubles idea clicks: same number here, same number there.
-
Count both trays and say the sentence. Touch each counter as you count both trays together, then say the full doubles sentence out loud: "4 plus 4 equals 8." Say it slowly, and have your child say it back with you. Saying the whole sentence — not just the answer — is what moves the fact into memory, so never skip it, even when the answer feels obvious. This spoken sentence is the habit the other nine games all build on.
-
Swap roles and let your child lead. Hand the lead to your child: now they place the counters and say "match me," and you do the copying. Being the leader changes the game — your child has to choose the number, place it, and check your work, which is quietly harder than copying. If you "make a mistake" on purpose now and then, your child gets the pleasure of catching it, and the checking habit gets stronger. Once your child leads confidently, try a first taste of doubles-minus-one together — 9+8 is one less than 9+9, so 17 — and these subtraction games pick up where the doubles leave off.
-
Climb the doubles one step at a time. Work up the doubles in order — 1+1, 2+2, 3+3, up toward 10+10 — adding one new double per session and warming up with yesterday's facts first. If the counting itself is still wobbly, warm up with these counting to 20 activities before the doubles climb begins. Keep each new double small and friendly: a child who owns 1+1 through 5+5 is ready for the bigger ones, and a child who is still counting on fingers should stay on the small doubles a while longer. Once 1+1 through 5+5 feel easy, these number bonds to 10 activities build on the same pairs from the addition side.
-
Stop after ten or fifteen minutes while it is still fun. End the game on a high note, even mid-streak — especially mid-streak. Say it out loud so your child hears the rule: "We stop while it is still fun, so tomorrow we want to play again." Put the counters away together (counting them in as doubles is one last quiet round), and leave the twin trays set out on the table; a child who sees them tomorrow will often start the game themselves. Younger siblings can play along with 1+1 and 2+2, and these counting activities for toddlers suit the little ones at the same table.
Make it easier
Camp on doubles up to 5+5 for the first week or two; the pattern clicks faster with small numbers. Use big counters (blocks, jar lids) and let your child count each side from 1 — never rush past counting. Play Mirror Match as a team against a stuffed animal "opponent" so nobody loses. Still building 1–10? Start with the counting to 10 activities linked in Step 2 before the doubles climb.
Make it harder
Double Dice with a 10-sided die, reaching all the way to 10+10. Doubles Bingo on a 4×4 grid, calling doubles-plus-one facts once plain doubles are instant. Add doubles-minus-one: 9+8 is one less than 9+9, so 17 — that's subtraction sneaking in, and the subtraction games linked in Step 6 pick up where this leaves off. Turn the doubles answers into skip counting by twos — chant 2, 4, 6 … 20 while hopping (the hopscotch game already does this). Race a sibling or parent: who can lay out all ten doubles facts with counters first, saying each sentence aloud?
Other ways to play it
- Build Mirror Match with LEGO bricks: two identical towers, knocked down together afterward.
- Play Double Dice in the car: call out any number from 1 to 10, and your passenger doubles it before the next stoplight.
- Lay the domino doubles end to end as a "doubles train," chanting each sum as you add a car.
- Ten-Frame Twins with beans is nearly silent — a good calm-down game after loud ones.
How it changes by age
- Ages 6–8. Six-year-olds should camp on 1+1 through 5+5 until the answers come without counting, then climb toward 10+10. Seven-year-olds can usually take the full ten facts plus doubles-plus-one. Eight-year-olds who are ready can run near-doubles in both directions and start using doubles as mental-math shortcuts. Younger siblings (4–5) can play Mirror Match with 1+1 and 2+2, and the counting activities for toddlers linked in Step 8 suit the little ones at the same table. Follow your child's ease, not their birthday.
What they're learning
Doubles facts 1+1 through 10+10, moving toward instant recall. Pattern spotting: every double's answer is even, and the answers climb by 2. Derived facts: doubles-plus-one and doubles-minus-one as a first mental-math strategy. Skip counting by 2s: the doubles answers in order — the hopscotch game builds directly on this. Number bonds to 10: doubles 1+1 through 5+5 are bonds in disguise — see the number bonds to 10 activities linked in Step 7 for the full set. Turn-taking, subitizing (reading dice pips at a glance), and fine-motor control from all the placing, dealing, and hopping.
Clearing up
Two minutes: counters go back in their jar (count them in as doubles — one last round), dominoes back in their box, cards rubber-banded. Let your child do the sorting; putting the pairs away is quiet doubles practice in disguise.

What doubles are, and why children learn them first: doubles addition games teach the ten facts where both numbers match — 1+1, 2+2, all the way to 10+10. They are the first facts most 6- to 8-year-olds truly memorize, because the pattern is impossible to miss: every answer is even, and each climbs by exactly 2. Know 6+6=12 cold, and 6+7 takes a heartbeat — that is why doubles are the foundation of mental math. The ten facts, in the order most children learn them: 1+1=2, 2+2=4, 3+3=6, 4+4=8, 5+5=10, 6+6=12, 7+7=14, 8+8=16, 9+9=18, 10+10=20. Stick this list on the fridge as a reference — glance at it when anyone is stuck, and retire it once the facts come on their own. The ten games, each teaching the same facts a different way — rotate them rather than repeating one. Mirror Match is the first game, walked through step by step in the Instructions above: two identical trays, matching counters, and the spoken sentence every time. Double Dice: roll one die and double it — roll a 5, say "5 plus 5 equals 10." Take turns; first to collect all six doubles (1+1 through 6+6) wins. One die means no adding step to get wrong — the whole game is the doubling. A 10-sided die reaches 10+10 once 6+6 feels easy. Domino Doubles Hunt: a double-six set is a doubles lesson in disguise. First, hunt: spread the dominoes face-up, find all seven doubles (0|0 through 6|6), and add each as you find it — 5|5 means "5 plus 5 equals 10." Then play: draw a domino, add both halves, calling "double!" or "not a double!" first. Kids love the hunt more than the adding — which is why the adding sticks. Pair Hunt: send your child hunting for pairs — two shoes, two socks, two gloves, two identical mugs. Each pair is a living doubles fact: three pairs of shoes means "3 plus 3 equals 6 shoes." Line them up and count everything at the end. A tidy-up game in a math costume; the doubles sentence writes itself. Ten-Frame Twins: draw two ten-frames (two rows of five boxes) — or cut the lid off an egg carton. Drop the same beans into each: 7 and 7, count to 14, announce "7 plus 7 equals 14." The frames cap the game at 10+10 and keep big doubles countable. Save them; a week's worth lined up shows answers climbing by 2. Snack Doubles: two identical bowls, the same number of crackers or berries in each. Your child counts both, announces the double ("8 plus 8 equals 16!") — then eats the evidence. Change the snack weekly; the game never gets old. Doubles Slap: strip the face cards and split the deck, face-down. Flip one card each; first to say the double and slap the pile wins both — flip a 9, shout "18!" Aces count as 1. Loud and fast, with plenty of doubles per game. Doubles Bingo: draw a 3×3 grid of even numbers from 2 to 20 (repeats fine). The caller announces facts — "double 7!" — and players mark 14 with a button. First full row shouts "doubles!" Let your child choose their nine numbers. A 4×4 grid with doubles-plus-one calls works once plain doubles are instant. Doubles Hopscotch: chalk pairs of squares on the driveway — two side by side, ten pairs down. Hop with both feet, chanting: first pair "2!", second "4!", up to "20!" at the tenth. The whole body learns 2, 4, 6 … 20 — skip counting by twos in sneakers. Near-Doubles Bridge: honest version first — doubles-plus-one only works when the double underneath is automatic. Know 7+7=14 cold, and 7+8 is just "one more" — 15. Deal two cards; if they differ by exactly 1, solve the smaller double, then add 1, saying it aloud: "6 plus 6 is 12, so 6 plus 7 is 13." Start with plus-one; doubles-minus-one waits a week. Still counting doubles on fingers? Park this game — the bridge needs solid ground. If your child starts spotting doubles unprompted — two rows of windows on a building, the pairs of shoes by the door, the headlights on cars — the pattern has landed. That is the entire goal of these games: not ten memorized answers, but a way of seeing numbers they will use for years.
