Step-by-step explanation:
The strategy that will best help accelerate the growth of the grade-level readers is option B: Using guided reading groups to assign students texts at their independent reading level and asking them to complete comprehension questions.
This strategy allows students to read texts that are at their appropriate reading level, ensuring that they can understand and engage with the content. By completing comprehension questions, students are actively processing and reflecting on the text, which further enhances their reading comprehension skills.
For example, students can be placed into small groups based on their reading level, and each group can be provided with books that match their individual abilities. The teacher can then guide the group discussions and ask relevant comprehension questions to promote deeper understanding of the text.
