Position and Direction - Move on a Grid - Presentation

In today's mathematics lesson, students will delve deeper into the concept of coordinates by exploring how to translate points on a grid. Translation refers to moving a point or an object to a new position on the grid without altering its orientation. The class will begin with a practical exercise where students place a small cube at the coordinate (1, 1) and then move it one unit up and one unit down, observing that the cube returns to its original position. Further movements, such as shifting the cube three units to the right and then to the left, will reinforce this understanding of translation and its effect on coordinates.

Subsequent activities are designed to enhance students' grasp of translation by instructing them to move objects on the grid by specific units in various directions and then record the changes in coordinates. For example, students will translate a cube placed at coordinate (3, 3) two units up and down, and three units left and right, noting that it returns to its starting point. They will also engage in more complex translations, such as moving a point six units right and three units down or translating shapes like rectangles and squares, recording the coordinates before and after the movement. The lesson includes opportunities for discussion, reasoning, and independent work, where students can apply their knowledge, describe translations in reverse, and understand the importance of following left and right movements when describing translations.
