I will check your reading activity with a gun on the screen of this laptop. (A gun is a selecting program on the computer.) When a number shows up on the screen, the student should come up here and read one part aloud. This reading text is divided into 4 parts. Draw your attention to me. I will fire the gun. ( Number 3 appears.) Who is Number 3? The student of Number three should come up here and read Part 1 loudly. Make your voice high. Don't make your voice soft. OK. Good! Go back to your seat.

Would you check the directions and correct errors? I appreciate your help.

They seem clear to me.

Based on the provided text, here is a corrected version of the directions:

"I will now initiate a reading activity using the selection program on this computer screen, metaphorically referred to as a 'gun'. Each part of the reading text has been divided into four sections. Pay attention to me as I start the activity. When a number appears on the screen, the corresponding student should come forward and read aloud the assigned part. For example, if Number 3 appears on the screen, the student designated as Number 3 should come up and read Part 1 loudly, making sure to use a high voice and not speak softly. Once the reading is complete, the student can return to their seat. Thank you for your cooperation."
