Lesson: Translations on a Coordinate Plane Mathematics • 8th Grade

In this lesson, we will learn how to apply the concept of translation to a point or a geometric shape and determine the coordinates of a translated image on the xy-plane.

Lesson Plan

Students will be able to

understand translation on a coordinate plane as the movement in the direction of the and the movement in the direction of the ,
understand the coordinate transformation that represents a translation,
translate points, line segments, and shapes on the coordinate plane given the coordinate transformation of the translation.

Lesson Worksheet

Q1:

The point has been translated three right and three down. What are the coordinates of the image?

Q2:

Start with point . Translate it by 5 units to the left and 2 units up. Follow this with a translation of 5 units to the right and 4 units up. What are the new coordinates?

Q3:

Determine the coordinates of the image of point of quadrilateral after a translation 5 units left and 3 units down.
