Mrs. Marshall is demonstrating her instructional strategy of "repeated readings" where the student's will repeat and read the same passage over and over again until they can read it with no errors.
Samuel, a student with ADHD is causing trouble in the back of the classroom. Mrs. Marshall fears that his behavior might cause a ripple effect and other students will also begin to cause trouble
