[br][br]Some objectives with gaining the students to play Tetris Game;[br][br]Transformation Geometry:[br][list][*]7.C.4.1.[br]Determines whether they are matched by comparing planar shapes.[br][/*][*]7.C.4.4.[br]On the post, he discovers that each point on the shape is subject to a[br]transformation in the same direction and magnitude.[br][/*][*]8.C.2.1.[br]The point forms images of the line segment and other planar shapes under[br]rotation.[br][/*][*]8.C.2.2.[br]It turns out that each dot on the figure is subject to rounding around a point[br]in a certain angle in the clockwise or anticlockwise direction, and that figure[br]and image are the same.[br][/*][*]8.C.2.4.[br]Shapes form images that appear at most two consecutive displacements,[br]reflections, or rotations.[/*][/list]This game can be played by 8-17 years old children. I will recommend especially 7[sup]th[/sup][br]or 8[sup]th[/sup] grade students because they have more information about[br]transformation geometry. Also, they play this game more conscious. My main[br]purpose is that students should think more critically with using their imagination[br]and information related with transformation geometry. [*][br][/*]
