TEKS § 111. 4. Grade 2 B) Knowledge and skills. (1) Mathematical process standards. The student uses mathematical processes to acquire and demonstrate mathematical understanding. The student is expected to: a) apply mathematics to problems arising in everyday life, society, and the workplace; b) use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution; 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; d) communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate.

What is transformation? The different ways that a figure or shape can be changed to either flip(reflection), turn(rotation), slide(translation), or resize.

Examples of Transformations Ex #1: turn(rotational) Transformation. Ex #2: Flip(reflection) Transformation.

What is translation? Sliding a figure or shape without rotating, flipping, or resizing. The shape will look exactly the same, it will just be in a different spot.

Examples of Translation Ex#1: Ex#2:

What is Reflection? The way a shape or an image would be seen in a mirror. By folding an image in half, there should be a reflection of the same half of the image on the other side, that is reflection.

Examples of Reflection Ex#1: Ex#2:

What is Rotation? A circular movement. A point is set in the center and the whole shape or image can be moved except for that center point.

Examples of Rotation Ex#1: Ex#2:
