Milk Cap Math: MADS Elimination



Here is another milk cap math game for basic +/-/x/division practice. My 15yo daughter thought of the name, MADS Elimination. (Thanks!)

The object?

M: multiply
A: add
D: divide
S: subtract

...in order to eliminate all milk caps on the playing field. (Before you go completely MADs!)

You'll need:
  • two sets of 10 milk caps (any color), numbered 1-10
  • two, 1-6 dice
To play the game, each player forms a line of milk caps, 1-10. Players take turns rolling the dice. When dice are rolled, the player may choose to multiply, add, divide, or subtract. So, for example:

Dice rolled: 3 and 5

I can:

M: 3 x 5 (won't work since my caps are 1-10)
A: 3 + 5 = 8
D: 5 / 3 = 2.5 (won't work)
S: 5 - 3 = 2

So I could eliminate either the 2 or the 8 cap. If the cap(s) has already been eliminated, I lose my turn. The first player to eliminate all caps, wins.

You can make this a little easier (preschool) by using 6 caps (1-6) and one die (1-6) and removing caps from the table as you roll each number.

You can make this a little harder by using bigger numbers (on the caps) or having the option of rolling multiple dice. For example, you could roll three, 1-6 dice, and make a number sentence using all three numbers. (You could also use dice with different numbers: 0-5, 4-9, etc.)

Example using 3 dice:

I roll: 1,3,4

I could do any number of combinations...I won't list them all, but for example:

3 - 1 + 4

1 x 4 - 3   (You could even talk about order of operations here.)

4 - 1 + 3

Lots and lots of possibilities for this game!

Running out of math caps yet?? ;)

This is another great math workbox game! ;)

Math App Saturday (#2, Add/Subtract/Mult/Divide)

Saturday series on using educational apps for iTouch/iPhone/iPad continues with games that promote skills practice with addition, subtraction, multiplication, and division. At posting, they are all FREE...

Math Zombie
In 10 seconds (or without the time mode), combine numbers to equal the number shown. The more numbers you use, the more points you earn. Practices addition facts to 20. All ages enjoy the game. Since you can set the time mode on or off, it also provides a challenge appropriate for a variety of levels.

Math Races
Skills practice in addition, subtraction, multiplication, division. Presentation isn't terribly exciting...if you're looking for traditional fact skills practice, this is it.

Burn Your Brain: Math

FAST paced game. You are presented with a math problem and you must immediately say whether the number sentence is true or false. Challenging!

24 Lite
"An addictive new take on a classic math card game! The goal of the game is deceptively simple: make the number 24 using the four given numbers and basic arithmetic -- addition, subtraction, multiplication and division."

Tri-Ominoes (Addition/Subtraction Game)


Tri-Ominoes, a game played similar to dominoes, provides addition and subtraction practice. When players lay a piece, they must add the three numbers on the triominoe as well as keep track of their total points. Since the game is played until someone reaches 400, it provides a lot of practice in adding and subtracting. (The subtracting comes in when a player must draw a triominoe...a loss of 5 points for each that must be drawn.) Bonus points are awarded for unique configurations of triangles, such as completing a hexagon.

We bought this game this weekend and kids ages 7-14 as well as adults have been playing and enjoying it ever since. :)
