Players take turns rolling two dice and adding the numbers. They keep a running total, and the first to reach exactly 100 wins. If they go over 100, they must subtract their roll instead. Great for addition and subtraction practice!

Variations:
- Use 3 dice for higher grades
- Change target number for different skill levels
- Allow multiplication of dice numbers for upper grades

# data[].attributes.body
Roll two dice and find all the factors of the product. For example, if you roll a 6 and a 4, the product is 24. Players must list all factors (1, 2, 3, 4, 6, 8, 12, 24). The player who correctly lists all factors first wins. Perfect for grades 4-6!

# data[].attributes.body
Players roll 2-4 dice each and create the largest (or smallest) number possible. Compare numbers using >, <, or =. Great for place value understanding! For younger grades, use 2 dice; for older grades, use more dice and include decimals.

# data[].attributes.body
Deal 4 cards (face cards = 10, aces = 1). Players must use all four numbers and any mathematical operations (+, -, ×, ÷) to make 24. First player to find a solution keeps the cards. Most cards at the end wins! Great for grades 4-6.

Example: 8, 3, 4, 2 → (8 - 2) × 4 - 3 = 24

# data[].attributes.body
Deal out all cards. Each player flips 2-3 cards (depending on grade level) to create a number. Highest number wins! For upper grades, include decimals by designating one card as tenths/hundredths. Great for understanding place value.

# data[].attributes.body
Each player flips two cards and adds them together. The player with the highest sum wins the round. For younger grades, use number cards only. For older grades, include face cards and more complex operations.

# data[].attributes.body
Write numbers 1-12 on slips of paper and add 3-4 'BANG!' cards. Players draw a card and multiply it by the target number (e.g., practicing 7 times tables). If correct, keep the card. If you draw 'BANG!', return all cards! Most cards at the end wins.

# data[].attributes.body
Play rock-paper-scissors with a partner.

On “rock,” each player shows a number using their fingers (1–12).

A fist = 5

A fist + 2 fingers = 7, etc.

Multiply the two numbers together as fast as you can.

First person to say the correct answer wins a point.

Play to 10 points (or set a timer and see who has the most points when time’s up).

Winner stays on for elimination

# data[].attributes.body
Students stand in two lines. First student says '3' (or target number), next student multiplies it by 1, next by 2, etc. If a student makes a mistake, they sit down. Last student standing wins! Great for quick recall of multiplication facts.

# data[].attributes.body
One student stands behind another seated student. Teacher shows a multiplication problem. First to answer moves to next student. If standing student wins, they continue; if seated student wins, they become the standing challenger.

# data[].attributes.body
Create a large number line on the floor with tape. Students solve addition/subtraction problems by physically jumping forward/backward on the line. For multiplication, they can do equal-sized jumps. Great for kinesthetic learners!

Variations:
- Add decimals
- Include negative numbers
- Use fractions

# data[].attributes.body
Divide class into teams. Call out geometric properties (e.g., 'find something with 4 right angles'). One student from each team races to find and touch an object with that property. First team to 10 points wins! Great for geometry review.

# data[].attributes.body
Students sit in a circle. First student starts a math story problem ('I have 15 marbles'). Next student adds to it ('I give away 3'). Next student must give the current total and add another element. Continues until a student makes a mistake. Great for mental math!

# data[].attributes.body
Teacher/student thinks of a number within agreed boundaries. Others ask mathematical questions that can only be answered with yes/no: 'Is it even?', 'Is it a multiple of 5?', 'Is it greater than 50?'. Great for developing mathematical reasoning!

# data[].attributes.body
Skills: Number sense, parity

How to play: Roll one die. Predict whether the result is even or odd before rolling. Keep score of correct predictions.

# data[].attributes.body
Skills: Multiplication facts

How to play: Roll one die. Multiply the number by 2, 3, 5 or 10 (choose depending on skill level). Players keep score of correct answers.

# data[].attributes.body
Skills: Subtraction

How to play: Roll two dice. Subtract the smaller from the larger. Keep score of correct answers or speed.

# data[].attributes.body
Skills: Addition or multiplication

How to play: Students write 6 sums on their mini whiteboards (e.g., 2+3, 4+5). Teacher rolls dice and calls out sums; students cross off if they have the answer.

# data[].attributes.body
Students write a number on a post it note and sticks it on their partners back.

The student has to ask yes/no questions to answer. Use a 100 grid and whiteboard marker to cross out/circle numbers they have found from their clues

# data[].attributes.body
Skills: Place value, comparing numbers

How to play: Each player rolls 4 dice to create the largest (or smallest) 4-digit number possible.

Differentiation:

Support: Use 2–3 digits.

Extension: Add decimal points or compare 5-digit numbers.

# data[].attributes.body
Skills: Multiplication fluency

How to play: Roll two dice. Multiply the numbers and fill in a blank multiplication grid.

Differentiation:

Support: Use a times table chart.

Extension: Use 10- or 12-sided dice or roll 3 dice and multiply all.

# data[].attributes.body
Focus: Number sense, place value, odds/evens, multiples
How to Play:

Label classroom corners with numbers or categories (e.g., Odd, Even, Multiple of 3, Less than 10).

Teacher calls out a math fact or number (e.g., “12”).

Students run to the corner that matches the property.

Teacher randomly eliminates one corner — those students are out or must sit for a turn.

# data[].attributes.body
Focus: Counting, skip counting, ordering numbers
How to Play:

Lay out a number line on the floor using paper or tape.

Two students race by solving problems and moving to the correct number (e.g., start at 0, move ahead by solving “+4,” then “x2,” etc.).

First to the end wins.

# data[].attributes.body
Focus: Mental math
How to Play:

One student sits in the “hot seat” with their back to the board.

Teacher writes a number on the board (e.g., 36).

Class gives math clues (e.g., “It’s a multiple of 6 and 9”).

The hot seat student guesses the number.

# data[].attributes.body
Focus: Word problems, logic
How to Play:

Students sit in groups. A word problem is passed around.

Each student does one step or writes their thinking before passing it on.

Last student writes the final answer.

Then, groups share solutions to compare methods.

# data[].attributes.body
Focus: Fluency and fact recall
How to Play:

In pairs, students flip cards simultaneously.

If the sum/product is a specific target number (e.g., 12), they call “Snap!” and take the pile.

# data[].attributes.body
Focus: Comparing and ordering fractions
How to Play:

Each player flips two cards to make a fraction (smaller on top, e.g., 3/7).

Players compare fractions; larger wins.

Can record as decimal equivalents if needed.

# data[].attributes.body
Focus: Mental addition

How to Play:

In pairs, students take turns drawing two cards, add them, and keep a running total.

First to reach 100 wins.

Bonus: Use number lines or mental rounding strategies to explain approaches.

# data[].attributes.body
Focus: Algebraic thinking
How to Play:

Teacher draws two cards, announces the result (e.g., “One card is 7. The total is 15. What’s the missing card?”).

Students mentally calculate and hold up the answer.

Welcome to Splat! You are only moments away from a VERY POWERFUL, highly interactive number sense strategy that can be used at any grade level!

# data[].attributes.body
You will need: • 2 dice • 2 different-coloured sets of 13 counters The aim of the game is to get 4 of your own counters in a row. Roll the 2 dice. Add the numbers together and place a counter on that number. Take it in turns until a player wins or the board fills up.

# data[].attributes.body
Roll dice and colour that amount on a hundred board. Keep rolling and counting on until you reach 100. Count how many times you had to roll the dice. Can be done in pairs to see who reaches 100 first.

# data[].attributes.body
Students stand in a circle and teacher decides on a " magic " number.

Students take turns going around the circle counting according to teacher instructions ( i.e counting in 1', 2's, 5's, 10's )

The student who lands on the magic number is out and sits down. Game starts again until all students are out, leaving 1 winner.

# data[].attributes.body
Players take turns to roll a dice and move in any direction on a number line. First person to make it to the end of the number line wins.

Teacher Versus class

or

Student Versus student

student 1 ( or teacher) picks a number card ( 1-9) and places it in the Tens column. Student 1 ( or teacher) then picks a number card and puts it in the ones column.

Call out 2 digit number made

Student 2 does the same.

bigger number wins
