Background • The students would apply mathematical thinking, and knowledge in order to describe, identify, and work with geometric figures’ transformations. • Grade 4

Transformation • A transformation moves a figure to a new position without changing its shape or size. • Imagine that you are in your room and you are tired of the same arrangement, so you decide to move things around like your bed. Even though now your bed is in a new spot it is still the same bed with the same dimensions; the same thing happen to geometric figures, they can move to different places but they remain the same.

• Example of transformation: The geometric shape moved from one place to another without changing its size or shape.

Translation • Translation moves a figure in a straight direction. • Imagine that you are at the park, and you decide to get on the slide. First you are at the top, but after you slide you are at the bottom of the slide. So, your body translated from the top to the bottom, but you are the same you did not change in size or shape.

• Example of translation

Reflection • A reflection of a figure gives it a mirror image over a line. It is like you are flipping the figure over a line. • When you wake up each morning, you go to the restroom and you face the mirror, and you see your reflection. It is still you, but with an imaginary line between you and your reflection.

Rotation • When rotating, a geometric figure moves about a point. • Let’s supposed that we are so tired from school that we just want to go home, so what we do? We look at the clock until we see the clock hands move from one number to the other. Yes, they are rotating from a fixed point and that is the center of the clock.
