## Attributes: Reason with Shapes and their Attributes Game

**Buy this Game on TeachersPayTeachers – $4**

MAJOR CONCEPT: Attributes of Shapes

NUMBER OF PLAYERS: Two to four

NUMBER OF PAGES: 107

MATERIALS: Thirty-two cards in sets of four. In each set, the figures on the cards are the same size and the same shape but they are different colors: one green, one red, one blue, and one yellow.

EXTRA CARDS/SHAPES: There are over 96 Different Shapes/Coors/Sizes Cards included for more advanced students.

**RULES:**

For example, the deck has four cards with small circles: one green, one red, one blue and one yellow. Each figure has three attributes, color, shape, and size.

The dealer shuffles the deck and deals three cards, face-up, to each player. The next card is turned face-up in the center of the table and the remainder of the deck is placed face-down where all players can reach it. The players build a row of figures, extending to the right of the first face-up figure. Each figure differs from the one on its left in exactly one attribute.

The player to the left of the dealer is the first player. If he has a figure that differs from the one turned up by the dealer in exactly ONE attribute, he places it face-up to the right of that card and the play passes to the player to the left. That player must play a figure that differs from the one played by the last player in exactly one attribute. If a player does not have a card to play, that player takes the top card form the deck and the play passes to the left.

The first player to run out of cards is the winner.

**VARIATIONS:** Instead of building a row of figures that differ from their neighbors in exactly one attribute, the players can build a row of figures that differ from the neighbors in exactly two ways or exactly three ways. The deck can be changed, also, by increasing the number of attributes of each figure. For example, another thirty-two cards can be made that are similar to the thirty-two cards described above except that the interiors of the figure are also colored. When all sixty-four cards are put together, each figure has four attributes, shape, size, color, and interior. Then the game can involve building rows of figures differing in exactly one, two, three, or four attributes.

Use the Extra Shapes and create a different deck each time you play.

### Grade 1 & 2: Reason with Shapes and their Attributes.

**CCSS Math 1.G.A.1** Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

**CCSS Math 2.G.A.1** Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.1 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
