Scratch for Educators

Visiting the 4 Quadrants

Objectives

  1. To identify the 4 quadrants of the coordinate plane.
  2. To write a Scratch program using motion and text.

Overview

The x-axis and the y-axis divide the coordinate plane into four quadrants. In Quadrant I, x is positive, and y is positive. In Quadrant II, x is negative, but y is positive. In Quadrant III, x is negative, and y is negative. In Quadrant IV, x is positive, but y is negative.

Proceedure

Start a new project on the Scratch website and make a Scratch program that:

  1. Starts the Scratch cat at the origin.
  2. Moves the Scratch cat to Quadrant I.
  3. Makes the cat say, I'm in Quadrant I now.
  4. Moves the Scratch cat to Quadrant II.
  5. Makes the cat say, I'm in Quadrant II now.
  6. Moves the Scratch cat to Quadrant III.
  7. Makes the cat say, I'm in Quadrant III now.
  8. Moves the Scratch cat to Quadrant IV.
  9. Makes the cat say, I'm in Quadrant IV now.

Be sure to share your Scratch program by clicking on the Share button near the upper right of the screen. It would be good to add information in the Instructions and Notes and Credits sections as well.

Evaluation

You will be marked competent for this assignment if you have:

  1. A Scratch program on your Scratch website.
  2. A Scratch program that moves the cat to each quadrant.
  3. Correct spelling of each quadrant in the correct location.
