**TEKS Objectives**

(7) Geometry and spatial reasoning. The student generates geometric definitions using critical attributes. The student is expected to identify essential attributes including parallel, perpendicular, and congruent parts of two- and three-dimensional geometric figures.

(8) Geometry and spatial reasoning. The student models transformations. The student is expected to:

(A) sketch the results of translations, rotations, and reflections on a Quadrant I coordinate grid; and

(B) identify the transformation that generates one figure from the other when given two congruent figures on a Quadrant I coordinate grid.

1. http://www.mathsisfun.com/geometry/transformations.html. Math is fun has animations regarding transformation, reflection, and rotation. By grade 5, students are expected to learn transformation and their purposes when it comes to a grid. Moreover, STAAR test has a large portion dedicated to geometry.

2. http://www.mathworksheets4kids.com/straight-lines/parallel-perpendicular-intersecting-lines.pdf. Math Worksheets for Kids has very thorough worksheets regarding parallel, perpendicular, and intersecting lines. By 5th grade, students are expected to recognize transformations, lines, and be able to draw them on a quadrant.
