```Geometric BingoLawrence, Anne                  Wells Community Academy                                942-2580                              Objectives:

Learners in grades 7-10 will be able to name and identify the names of
20 geometric shapes.

Students will derive the properties of various geometric figures as
questions are formulated to distinguish the shapes.

Apparatus Needed:

Geometric Bingo game card, envelope of geometric chips for each player.
Overhead projector and transparent game card with transparent chips.
Teacher  must prepare game materials as follows:  Game cards can be
made from construction paper and can be laminated for repeated use.
Each board should be 5x5, or contain 25 one-inch square spaces. Label
the four corners on the board "FREE"and add one of the following terms
under the word "FREE": point, line, line segment, and ray. Cut at least
twenty-one two centimeter square chips for each student and place these
in envelopes for them.  Each chip should have a picture of one of the
two-dimensional geometric shapes commonly called a plane. Consult the
glossary of any geometry textbook for a list of terms for geometric
figures.

Recommended Strategy:

Supply one game card for each player. Each card should have twenty-one
spaces or places with the geometric names that correspond to each of
the chips in the envelope. Names should be typed onto adhesive labels
and entered onto the game board in a random fashion.

Prepare an overhead transparency of the game card and chips for
purposes of explanation, discussion and calling the game.

Directions:  Introduce this activity by treating the entire class as theopponent.  Use the transparency on the overhead projection as the display board. Students work individually or as teams. Teacher explains that the FREE space names--"point","ray","line","line segment"--are givens which help us understand the descriptions of the twenty shapes that make up the game. Players should then be directed to look at the center FREE space and instructed to take the chip from their envelopes that has the stick-on tag. Players earn this center FREE by writing a description of their body size or dimension.  The student chooses a term from an arbitrary list of personal sizes that can be written on the chalk-board,i.e., compact, midsize, fullsize, sleek; or, obelisk, rotund, statuesque, etc.  Student selects and writes his/her body type on the tagged chip and attaches it to the back of the game board over the center FREE space. This part of the introduction is mainly motivational; thus, it is optional. The game proceeds as follows: l.  Caller draws a figure from the envelope containing the cut-up game chips and matches it with the form on the display board.  Students are then encouraged to pronounce the name of the shape, locate the figure among their game pieces, and place it in the appropriate place on the board. 2.  The goal is to have players formulate a series of questions or opinions regarding properties of the figures as they attempt to bingo. 3.  Examples of valid questions are as follows:    "Is your figure a plane?"    "Does your figure have diagonals?"    "Is this figure a basic Sesame Street shape?"    "Does this figure contain one pair of parallel sides?"Scoring:  Players win by getting bingo horizontally, vertically, or diagonally. Players game chips may be left on the board after each game until all shapes have been called on the display board. Conclusion: As students play "Geometric Bingo" they are actively thinking about the commonalities and differences exhibited by the figures and the strategical value of the questions they ask.  The game can be modified to include various skills throughout a geometry course.```
