Chocolate Chip Cookie Mining

You will need:

Each player will need a copy of the Cookie Mining Spreadsheet to complete.

Please have an adult's supervision for this activity.

The purpose of this game is to give the player an introduction to the economics of mining. This is accomplished through the player buying their "property", purchasing the "mining equipment", paying for the "mining operation" and finally paying for the "reclamation". In return the player receives money for the "ore mined". The objective of the game is to make as much money as possible.


The game provided each player with an opportunity to make the most money that a player could make with the resources provided. Decisions were made by each player to determine which properties to buy and which pieces of mining equipment should be purchased.

Each player should have learned a simplified flow of an operating mine. Also, each player should have learned something about the difficulty of reclamation especially in returning the cookie back to the exact size it was before the "mining" started.

1. Each player starts with $19 of play money.

2. Each player receives a cookie mining sheet and a sheet of grid paper.

3. Each player must buy his/her own "mining property" which is a cookie. Only one "mining property" per player. Cookies for sale are:

Store Brand Chocolate Chip Cookies - $3.00

Chips Ahoy - $5.00

Chips Deluxe - $7.00

4. After the cookie is bought, the player places the cookie on the grid paper and using a pencil, traces the outline of the cookie. The player must then count each square that falls inside the circle. Note: Count partial squares as a full square.

5. Each player must buy his/her own "mining equipment". More than one piece of mining equipment may be purchased. Equipment many not be shared between players. Mining equipment for sale is:

Flat toothpick - $2.00 each

Round toothpick - $4.00 each

Paper clips - $6.00 each

6. Mining costs are $1.00 per minute.

7. Sale of a chocolate chip mined from a cookie brings $2.00 (broken chocolate chips can be combined to make 1 whole chip).

8. After the cookie has been "mined", the cookie should be placed back into the circled area on the grid paper. This can be accomplished using the mining tools – No fingers or hands allowed.

9. Reclamation costs are $1.00 per square over original count.

1. No player can use their fingers to hold the cookie. The only thing that can touch the cookie are the mining tools and paper on which the cookie is sitting.

2. Players should be allowed a maximum of five minutes to mine their chocolate chip cookie. Players that finish mining before the five minutes are used up should only credit the time spent mining.

3. A player can purchase as many mining tools as the player desires and the tools can be of different types.

4. If the mining tools break, they are no longer usable and a new tool must be purchased.

5. The player(s) that make the most money be the end of the game wins.

6. All players win at the end of the game because they get to eat the remains of their cookie
