MathDice

™

and the

Flexibility of Numbers:

Numbers are incredible. As you play

MathDice

™

and your skills improve,

you will come to discover patterns

and relationships that will astound

you. Really!

To get you started down this path,

we’ve developed eight Practice Tables

that you can use to hone your skills.

The ﬁrst ﬁve tables each focus on a

different operation, and the ﬁnal

three WOW! Tables show examples

with multiple ways of reaching the

Target Number.

Once you work your way through

these stretching drills, you’re ready

for action!

The Fast Fun Game of Mental Math

Contents:

• Two 12-sided Dice

• Three 6-sided Dice

• Travel Bag

• Instruction Booklet

Ages 8 to Adult

Fun for players of all math levels

For 2 or More Players

Play competitively, in teams, or practice

on your own.

Object: Use your math skills to

combine three numbers to match, or

come closest to, the Target Number.

™

7 x 4 = 28

To Play:

Start by rolling the two 12-sided

Target Dice. Multiply them together

to establish a Target Number. In the

example below, when you roll a 7 and

a 4 the Target Number is 28.

Then roll the three 6-sided Scoring

Dice to establish three Scoring

Numbers. In the example below, a

5, 2, and 3 are your

Scoring Numbers.

Note how each number is used once

and only once in each equation. This

rule is especially important to

understand

when the numbers are

used as

powers. The player who hit 28

used the “2” to raise the 5 to the

second power; the player who

reached 27 used the “3” to raise

–

2) to the third power.

The fun and ﬂexibility of this game is

in combining the three Scoring

Numbers in the most creative ways

to get the best answer.

2 19

Using the Scoring Numbers, create

an equation to calculate the closest

number possible to the Target

Number. Your answer could be above

the Target Number, below the Target

Number, or hit the Target Number

exactly, depending on the numbers

rolled and what you do with them.

To create your equation, use each

Scoring Number once and only

once, along with any combination

of the following operations: addition,

subtraction, multiplication, division,

powers, and roots. You may use the

Scoring Numbers and operators in

any order.

In our example, two players might

shout out the following…

5 6

7 8

9 10

(Remember, the Target Number is

28 and the Scoring Numbers are

5, 2, and 3.)

Player I shouts, “25!” (2 + 3) x 5

Player 2 shouts, “30!” 2 x 3 x 5

Player I shouts, “29!” 2

– 3

Player 2 shouts, “27!” (5 2)–

Player I shouts, “28!” 5

+ 3, hits the

Target Number exactly, and wins

the point.

1510 MATH DICE BOOKLET

COLOR: PRINTS BLACK

PAPER STOCK:

Scoring:

our goal is to beat your opponent by

getting closer to the Target Number,

faster. Once you have an answer you

are satisfied with, call it out. The first

player to call out an answer, claims

that number.

If the Target Number hasn’t been

reached, other players then have 15

seconds to respond with a new

answer that is closer to the Target

Number. (The player with the current

best answer must remain silent while

the other players try for a better

answer.) This play continues, with an

additional 15 seconds added after each

improvement, until one player hits the

Target Number exactly, the other

players forfeit the point, or the time

limit for calculating is reached.

The player with the closest number

at the end of the point must state

the equation p1-he or she used to reach

the answer. If it is correct, the point

is won. If incorrect, the player with

the next closest answer must state

his or her equation, and gets the

point if it is correct.

The first player to win four points

wins the game. Note: If you are

playing competitively, MathDice

™

is a

“mental math” game…pencil, paper,

or a calculator are not allowed.

Simpler Versions of Play:

MathDice

™

is a fun, educational game.

The rules above describe competitive

play. For your enjoyment, please feel

free to relax the rules in any way that

suits your group of players.

To lower the average difficulty of the

calculations, reduce the range of the

Target Numbers. To do this, you may:

• Roll only one 12-sided die to

establish a Target Number in the range

between 1 and 12. This version makes

a good game for players who are

more confident with addition and

subtraction skills, and just starting to

get a mastery of multiplication.

• Roll two 12-sided dice, and add the

two numbers together, to establish a

Target Number in the range

between 2 and 24. This version

makes a good game for players who

have confidence in their adding/

subtracting/multiplying skills, but are

not yet comfortable with more

advanced operations.

For a more cooperative environment,

choose from the following:

• Everyone who can match the best

answer given on a turn, gets a point

for that turn.

• Relax time constraints.

• Allow use of pencil and paper or

calculators.

• Work together to find as many

answers as you can that are close

to the Target Number.

• Have fun exploring the numbers

and their patterns!

Where It Started

MathDice

™

was invented by Sam

Ritchie, as a “Design a Game” math

workshop project for his sixth grade

class. Now a teenager, Ritchie is on

the United States Junior World Sprint

Kayaking team, and hopes to compete

in the Olympics some day.

Ritchie’s other hope is that MathDice

™

will make math more fun and

accessible for the generation of kids

now in elementary and secondary

schools across the country and

around the world.

Yeah!
