After playing this game the learners will be able to name
the combinations of primary and secondary colors that produce white
when added together.
Learners/Context; The learners are students in an introductory
physics class in either junior high or high school.
The game is designed to be played during or after a unit
considering color addition and subtraction. A distinction needs to be
made between color addition (mixing light) and pigment addition
(mixing "paint") which is truly a process of color subtraction.
Rationale; A game is an appropriate format for this situation
because it would be much more enjoyable to learn these combinations
within a game context than it would be if the students just simply
memorized the information.
Rules; Two to four people may play at the same time. Each
player attempts to form "suits" of cards that produce white when
added together. The first player to get a combination of seven cards
(two pairs and a triple), all of which produce this combination, wins
The game is played in the following manner:
- Seven cards are dealt to each player. The remainder of the
cards are set down between the players with the top card turned
- The player immediatedly to the dealers left has the option of
taking the card turned up or taking the first card on top of the
remainder of the deck.
- This player should then discard a card face up. The next
player then takes their turn continuing with this style of play
until somebody thinks they have won the game.
- The player who thinks they have a winning combination should
lay their cards down for inspection. If they have a combination of
cards that does not satisfy the requirements they are eliminated
from the game.
Each card is entirely of a single color except for a Venn diagram
at the upper left corner of the card. This diagram is to be used as a
key to help players determine what combinations of colors will
produce white. In addition to this is the name of the color above
each diagram. This is included for color-blind students. There are
six colors that are used: red, green, blue, cyan, magenta, and
The playing desk has a total of 60 cards, ten of each color. There
is also a card with the rules of the game.
Design Process I started by thinking of physics concepts that
are visual in nature. Color is an obvious choice. Also when teaching
the concept of color addition to students I have had problems coming
up with interesting activities for students to do. I contemplated
adding complexion to the game by adding cards with color subtraction
results (adding pigments) but felt it would only make to game to
