These math games for the classroom need a whiteboard, a deck of cards, a few dice or nothing at all, and each one fits in 5 to 15 minutes. They are written for teachers, math-club leaders and parents running a group of kids in grades 2–6. Every game below has rules, a worked example and the question that turns it from practice into problem solving. Several are two-player games, and the last one is a free daily puzzle for the interactive whiteboard.

Buzz
Kids stand in a circle and count up from 1, one number each. On any multiple of 7, or any number with a 7 in it, the player says “buzz” instead. Miss one and you sit down; the last few standing win.
Up to 40, the buzz numbers are 7, 14, 17, 21, 27, 28, 35 and 37. For grades 2–3, use multiples of 3 or 5 instead. For a harder round, buzz on multiples of 7 and “fizz” on multiples of 4, so 28 is “fizz-buzz”.
Thinking question: “Which two-digit numbers are buzz numbers for both reasons, a multiple of 7 with a 7 in it?” (Answer: 70 and 77.)
Multiplication War (two-player)
A times-table game for two players with a deck of cards, and one of the simplest multiplication games for the classroom. Take out the face cards; aces count as 1. Deal the deck evenly face down. Both players flip two cards at once and say the product of their own pair. The bigger product takes all four cards. On a tie, each flips two more and the winner takes all eight. Play for ten minutes; whoever holds more cards wins.
Example: you flip 7 and 8 (56), your partner flips 9 and 6 (54). You take the four cards. Every round is two times-table facts, and a kid who knows 7 × 8 at a glance calls the result first. For grades 2–3, add the two cards instead of multiplying.
Race to 21 (two-player)
Two players (or two teams) take turns counting up from 0. On each turn you add 1, 2 or 3 to the last number said. Whoever says 21 wins.
Go first against the class, win a few games in a row, then ask how you did it. The trick comes from working backward: if you say 17, the other side can only reach 18, 19 or 20, and you say 21 next. The same logic makes 13, 9, 5 and 1 safe. So the first player says 1 and then always jumps to the next number in 1, 5, 9, 13, 17, 21, which are 4 apart: whatever the other side adds, you add enough to make 4.
Once kids crack it, change the rules: race to 30, or add 1 to 4. They have to find the new safe numbers themselves (for adding 1 to 4, the jumps become 5).
Closest to 100 (two or more players)
Each player draws two blank 2-digit boxes and a plus sign: ☐☐ + ☐☐. Roll a die four times. After each roll, every player writes the digit in one of their boxes; once placed, it can’t move. Closest sum to 100 wins the round.
Worked example: the rolls are 3, 6, 5 and 2. The best possible answer is 35 + 62 = 97 (32 + 65 also makes 97). The tens digits 3 and 6 make 90, and the two leftover digits go in the ones places to add 7. No arrangement makes 98, 99 or 100.
Playing as the dice come one at a time is what makes it a game: a kid who puts a 2 in a tens box early has to decide where the next roll should go. Afterward, ask the class to find the best answer for that round’s four digits.
Roll to the Target
Roll two dice and write the 2-digit number they make on the board (a 4 and a 2 make 42). Then roll four more dice. Kids combine the four numbers with + − × ÷ to hit the target, using each number at most once.
Worked example: target 42, numbers 6, 5, 3 and 2.
- 6 × (5 + 2) = 42 uses three numbers.
- (5 × 3 + 6) × 2 = 42 uses all four.
- 6 × (5 × 2 − 3) = 42 also uses all four.
Score 1 point for hitting the target and 1 more for using all four numbers. If nobody hits it, the closest answer wins. Writing each answer as one line with brackets is good practice in order of operations.
Guess My Number
Think of a whole number from 1 to 100. The class may ask only yes-or-no questions, and you tally them on the board.
The best strategy halves the possibilities each time: “Is it more than 50?”, then “more than 75?”, and so on. Seven questions are always enough, because halving 100 seven times gets down to one number (2 × 2 × 2 × 2 × 2 × 2 × 2 = 128, which is more than 100). Six can fail, since 2 multiplied by itself six times is only 64.
Let the class play a few rounds before you share that. Then challenge them: “How many questions for a number from 1 to 1,000?” (Ten, because 2 multiplied by itself ten times is 1,024.)
Pyramid Swap
Each brick in a number pyramid is the sum of the two bricks under it. Each kid writes a bottom row of four numbers and builds up to the top:
| Row | Bricks |
|---|---|
| Top | 30 |
| Third | 15, 15 |
| Second | 8, 7, 8 |
| Bottom | 3, 5, 2, 6 |
Next, they copy the pyramid onto a fresh sheet, leave out some bricks (including at least one in the bottom row) and swap with a partner. To fill a bottom brick the partner has to subtract: here, if the 5 is missing, it is 8 − 3. The writer has to check their puzzle can be solved, which is its own lesson.
A daily whiteboard warm-up with MEC Games
MEC Games is our set of five free daily math games. Each day at midnight Eastern there is a new puzzle in every game, the same one for everyone, with a puzzle number. That makes it an easy interactive whiteboard math game for the first five minutes of class, or a warm-up on any projector.
| Game | What kids do | Builds |
|---|---|---|
| Hit the Target | Combine five number tiles with + − × ÷ to make the target | Mental math, order of operations |
| Stack Attack | Fill in a number pyramid where each brick is the sum of the two below | Addition, subtraction, working backward |
| Grid Lock | Fill a grid so no number repeats in a row or column and each cage makes its target | Arithmetic, logical reasoning |
| Clue Crew | Use clues to match people and things in a logic grid | Deductive reasoning, careful reading |
| Times Trail | Answer times-table facts to hop along a trail to the flag | Multiplication and division facts |
How to run it:
- Pick one game for the day and put it on the screen. Kids suggest the next move and say why; the class agrees before you tap.
- Write the puzzle number on the board so kids can find the same puzzle at home.
- Puzzles get harder through the week: Monday is easy, Tuesday to Thursday medium, Friday hard. Grid Lock and Clue Crew move from a 4×4 grid to a 5×5 on Fridays.
- Hints add 30 seconds to the timer, so the class can decide together whether a hint is worth it.
A times-table sprint on the whiteboard. Times Trail has a Practice tab that sits apart from the daily trail: pick any tables from ×1 to ×12 and run a 60-second sprint with the class calling out answers, or 20 facts with a volunteer at the board. A link like the 6 times table opens practice on that table, which makes it one of the quickest multiplication games for the classroom. A 12×12 facts chart shows which facts were quick, slow or missed on that computer.
The games are free and need no account. Progress and streaks are saved only in the browser that played, so a classroom computer keeps the class streak going.
Keep the games about thinking
- Ask for the why. After each round, one kid explains their answer at the board. A right answer with a reason is worth more than a fast one.
- Play in pairs. Two kids sharing one answer talk through their thinking, and quieter kids still get a say.
- Change one rule. Once a game is solved, a new target or a new limit makes it a fresh problem.
- Use them as review games. Match the game to the week’s topic: Multiplication War after times tables, Closest to 100 after place value, Roll to the Target after order of operations.
