TRANSFORMATIONS Anna Cortez Mathematics 1351

TEKS (b) Knowledge and skills. (1) Mathematical process standards. The student uses mathematical processes to acquire and demonstrate mathematical understanding. The student is expected to: (C) select tools, including real objects, manipulatives, paper and pencil, and technology as appropriate, and techniques, including mental math, estimation, and number sense as appropriate, to solve problems; (2) Number and operations. The student applies mathematical process standards to understand how to represent and compare whole numbers, the relative position and magnitude of whole numbers, and relationships within the numeration system related to place value. The student is expected to: (F) name the whole number that corresponds to a specific point on a number line.

TRANSFORMATIONS Transformation is the general term used for different types when shapes are manipulated. Ø Translations Ø Reflections Ø Rotations

TRANSLATIONS A translation is when a figures is move or slide in a straight direction. The figure cannot be reshape. The size cannot be change. Each point is slide on the same direction.

REFLECTIONS A reflection is when the figures is reflected across the axis It can also be call flip. The figures one mirrors the figures two. It cannot be reshape nor change sizes.

ROTATIONS A rotation is when the figures turns about a fixed point or center of rotation. The figures cannot change shape nor sizes Rotation is also call “turn” It can rotate clockwise and counterclockwise.
