What you will learn: • Delete a sprite and import a new sprite • Draw using the Pen feature of scratch • Make a simple script to draw circles • Use the “pen up” and “pen down” feature • Change the colour of the pen • Set the start position of the sprite • Make a sprite appear and disappear using show and hide

  3. Delete the cat sprite • Click the scissors button and delete the cat sprite
