Answer:
Mr. Miller can only assess one student at a time.
Step-by-step explanation:
It is given that Mr. Miller is helping his five students in the general education class who are having trouble in reading. He wishes to monitor their reading progress. Mr. Miller decides to use oral reading fluency to help the students.
He has done all the needful to improve his student's reading fluency by determining each student’s instructional level and by obtaining them passages.
But Mr. Miller can assess only one student at a time because each student is given a passage to read and Mr. Miller can listen to only one student reading at one time. Otherwise he will not be able to assess and monitor them.
Thus the answer is
Mr. Miller can only assess one student at a time.
