Mr. Yewr, Mrs. Linds, and Mr. Sands all teach fifth grade. For reading, they all switch students in order to take care of the highest reading group, the average reading group, and the low reading group. What is taking place in this scenario?

Between-class ability grouping

Explanation:

They are separating students based on the calculations they have regarding their reading ability, in this way, they will focus more precisely on particular cases, such as reinforcement and variation of rhythms for groups with less efficient reading ability, compared to the more advanced levels.
